Entitlement to a rating in excess of 10 percent prior to June 16, 2008, for degenerative joint disease of the right knee and in excess of 30 percent as of August 1, 2009, for degenerative joint disease of the right knee, post total right knee replacement. 2. Entitlement to a total disability rating based upon individual unemployability due to service-connected disabilities (TDIU). REPRESENTATION Veteran represented by: Disabled American Veterans ATTORNEY FOR THE BOARD A.M. Ivory, Counsel INTRODUCTION The Veteran had active military service from May 1976 to May 1982. This matter comes before the Board of Veterans' Appeals (Board) on appeal from a February 2008 rating decision issued by the Department of Veterans Affairs (VA) Regional Office (RO) in Columbia, South Carolina. By way of history, the Veteran filed a claim for an increased rating for her degenerative joint disease of the right knee in June 2007 and an October 2007 rating decision denied a rating in excess of 10 percent for such disability. Thereafter, additional evidence was received and a December 2007 rating decision continued the Veteran's 10 percent disability rating for her service-connected degenerative joint disease of the right knee. Thereafter, additional evidence was again received and the RO issued a rating decision in February 2008, which the Veteran appealed. In consideration of 38 C.F.R. § 3.156(b) (2012) (when new and material evidence is received prior to the expiration of the appeal period, it will be considered as having been filed in connection with the claim which was pending at the beginning of the appeal period), the Board finds that the Veteran's claim for an increased rating for her right knee disability has been pending since receipt of her claim in June 2007. See also Bond v. Shinseki, 659 F.3d 1362, 1367 (Fed. Cir. 2011). During the pendency of the appeal, a May 2009 rating decision granted a temporary evaluation of 100 percent for the Veteran's degenerative joint disease of the right knee based on surgical treatment necessitating convalescence, effective from June 16, 2008, to July 31, 2009, pursuant to 38 C.F.R. § 4.30. The May 2009 rating decision granted the Veteran a 30 percent rating, effective August 1, 2009. As the claimant will generally be presumed to be seeking the maximum benefit allowed by law and regulation, it follows that such a claim remains in controversy where less than the maximum available benefit is awarded. AB v. Brown, 6 Vet. App. 35, 38 (1993); Hart v. Mansfield, 21 Vet. App. 505 (2007). Therefore, this issue has been characterized as shown on the first page of this decision. The Board observes that the February 2008 rating decision also denied service connection for a left knee disorder, which the Veteran timely appealed. However, in a June 2012 rating decision, the RO granted service connection for degenerative joint disease, status post total knee arthroplasty, of the left knee. As such is a full grant of the benefit sought on appeal, this issue is no longer before the Board. After a careful review of the Veteran's claims file, including her VA examinations, the Board finds that, although an appeal was not received on the issue of entitlement to TDIU, it is now before the Board because it has been reasonably raised during the adjudicatory process of the underlying claim and is a component of the instant appeal. See Rice v. Shinseki, 22 Vet. App. 447,454-455 (2009). In this regard, the Board is cognizant that, in response to a July 2012 letter that referenced her claim for service connection for posttraumatic stress disorder (PTSD) and indicated that, if she believed that she qualified for a 100 percent rating based on an inability to secure and follow a substantially gainful occupation because of her service-connected disability, she should complete and return VA Form 21-8940 (Veteran's Application for Increased Compensation Based on Individual Unemployability), the Veteran indicated in a July 2012 statement that she did not believe that such applied to her. However, as will be discussed further herein, the issue of entitlement to a TDIU has been raised in the context of her claim for an increased rating for her right knee disability. Specifically, at the Veteran's September 2009 VA examination, it was noted that she was not currently employed. Her most recent work was as a schoolteacher, but her occupation was affected because she could not move up and down stairs, could not sit or stand for long periods of time, and had difficulty getting to a sitting position. As a schoolteacher, such was an impossible combination. Additionally, the June 2012 VA examiner noted that the Veteran's knee conditions impacted her ability to work in that she had to quit work because she taught at a private school that was not handicap accessible and she could not do the job. Therefore, as the Veteran was previously notified that she may file a TDIU claim in connection with her claim for service connection for PTSD and the evidence otherwises raises the issue of entitlement to a TDIU, the Board has taken jurisdiction over it as part and parcel of her claim for an increased rating for her right knee disability and, as such, the issue is included on the title page. The Board notes that, in addition to the paper claims file, there is a paperless, electronic (Virtual VA) claims file associated with the Veteran's claims. A review of the Virtual VA claims file reveals additional VA treatment records dated from February 2000 to April 2012, which were considered by the agency of original jurisdiction (AOJ) in the April 2012 supplemental statement of the case. The issue of entitlement to a TDIU is addressed in the REMAND portion of the decision below and is REMANDED to the RO via the Appeals Management Center (AMC), in Washington, D.C. FINDINGS OF FACT 1. For the appeal period prior to June 16, 2008, the Veteran's degenerative joint disease of the right knee is manifested by painful motion with functional loss equal to flexion to no worse than 120 degrees and extension to no worse than zero degrees, without instability or subluxation, ankylosis, cartilage removal, impairment of the tibia or fibula, or genu recurvatum. 2. For the appeal period prior to June 16, 2008, the Veteran's degenerative joint disease of the right knee is manifested by dislocated semilunar cartilage with locking, pain, and effusion. 3. For the appeal period since August 1, 2009, the Veteran's degenerative joint disease of the right knee, post total right knee replacement, is not manifested by chronic residuals consisting of severe, painful motion or weakness in the affected extremity, ankylosis, limitation of extension to 30 degrees or greater, or impairment of the tibia and fibula. CONCLUSIONS OF LAW 1. For the appeal period prior to June 16, 2008, the criteria for a rating in excess of 10 percent for degenerative joint disease of the right knee have not been met. 38 U.S.C.A. §§ 1155, 5107 (West 2002); 38 C.F.R. §§ 4.1, 4.3, 4.7, 4.14, 4.40, 4.45, 4.71a, Diagnostic Codes 5010-5260 (2012). 2. For the appeal period prior to June 16, 2008, the criteria for a separate 20 percent rating, but no higher, for dislocated semilunar cartilage of the right knee have been met. 38 U.S.C.A. §§ 1155, 5107 (West 2002); 38 C.F.R. §§ 4.1, 4.3, 4.7, 4.14, 4.40, 4.45, 4.71a, Diagnostic Code 5258 (2012). 3. For the appeal period since August 1, 2009, the criteria for a rating in excess of 30 percent for degenerative joint disease of the right knee, post total right knee replacement, have not been met. 38 U.S.C.A. §§ 1155 , 5107 (West 2002); 38 C.F.R. §§ 4.1, 4.3, 4.7, 4.14, 4.40, 4.45, 4.71a, Diagnostic Code 5010-5055 (2012). REASONS AND BASES FOR FINDINGS AND CONCLUSIONS I. VA's Duties to Notify and Assist The Veterans Claims Assistance Act of 2000 (VCAA) and implementing regulations impose obligations on VA to provide claimants with notice and assistance. 38 U.S.C.A. §§ 5102, 5103, 5103A, 5107 (West 2002 & Supp. 2012); 38 C.F.R §§ 3.102, 3.156(a), 3.159, 3.326(a) (2012). Proper VCAA notice must inform the claimant of any information and evidence not of record (1) that is necessary to substantiate the claim; (2) that VA will seek to provide; and (3) that the claimant is expected to provide. 38 U.S.C.A. § 5103(a); 38 C.F.R. § 3.159(b)(1). In Dingess/Hartman v. Nicholson, 19 Vet. App. 473 (2006), the United States Court of Appeals for Veterans Claims (Court) held that the VCAA notice requirements of 38 U.S.C.A. § 5103(a) and 38 C.F.R. § 3.159(b) apply to all five elements of a service connection claim. Those five elements include: 1) Veteran status; 2) existence of a disability; 3) a connection between the Veteran's service and the disability; 4) degree of disability; and 5) effective date of the disability. In Pelegrini v. Principi, 18 Vet. App. 112 (2004), the Court held that a VCAA notice, as required by 38 U.S.C.A. § 5103(a), must be provided to a claimant before the initial unfavorable AOJ decision on the claim for VA benefits. In the instant case, the Board finds that VA has satisfied its duty to notify under the VCAA. Specifically, a July 2007 letter, sent prior to the initial unfavorable decision issued in February 2008, and a January 2009 letter advised the Veteran of the evidence and information necessary to substantiate her increased rating claim as well as her and VA's respective responsibilities in obtaining such evidence and information. Additionally, the July 2007 letter advised him of the information and evidence necessary to establish an effective date in accordance with Dingess/Hartman, supra. Relevant to the duty to assist, the Veteran's service treatment records as well as post-service VA and private treatment records have been obtained and considered. The Veteran has not identified any additional, outstanding records that have not been requested or obtained. The Veteran was also afforded VA examinations in July 2007, September 2009, and June 2012 in conjunction with her increased rating claim on appeal. While the Veteran's representative argued in the July 2013 Appellant's Brief that her knee had not been examined since her total knee replacement surgery in June 2008 and that the VA examinations of record are too old to adjudicate her increased rating, the Board finds that such is not the case. Rather, after her June 2008 surgery, VA examinations pertaining to the current nature and severity of her right knee disability were conducted in September 2009 and June 2012. Neither the Veteran nor her representative have alleged that such are inadequate for rating purposes. Moreover, the Board finds that the examinations are adequate in order to evaluate the Veteran's service-connected right knee disability as they include an interview with the Veteran, a review of the record, and a full physical examination, addressing the relevant rating criteria. Therefore, the Board finds that the examination reports of record are adequate to adjudicate the Veteran's increased rating claim and no further examination is necessary. Thus, the Board finds that VA has fully satisfied the duty to assist. In the circumstances of this case, additional efforts to assist or notify the Veteran in accordance with the VCAA would serve no useful purpose. See Soyini v. Derwinski, 1 Vet. App. 540, 546 (1991) (strict adherence to requirements of the law does not dictate an unquestioning, blind adherence in the face of overwhelming evidence in support of the result in a particular case; such adherence would result in unnecessarily imposing additional burdens on VA with no benefit flowing to the appellant); Sabonis v. Brown, 6 Vet. App. 426, 430 (1994) (remands which would only result in unnecessarily imposing additional burdens on VA with no benefit flowing to the appellant are to be avoided). VA has satisfied its duty to inform and assist the Veteran at every stage in this case, at least insofar as any errors committed were not harmful to the essential fairness of the proceeding. Therefore, he will not be prejudiced as a result of the Board proceeding to the merits of her claim. II. Analysis Disability ratings are determined by applying the criteria set forth in the VA Schedule for Rating Disabilities, found in 38 C.F.R., Part 4. The Rating Schedule is primarily a guide in the evaluation of disability resulting from all types of diseases and injuries encountered as a result of or incident to military service. The ratings are intended to compensate, as far as can practicably be determined, the average impairment of earning capacity resulting from such diseases and injuries and their residual conditions in civilian occupations. 38 U.S.C.A. § 1155; 38 C.F.R. § 4.1. Where there is a question as to which of two evaluations shall be applied, the higher evaluation will be assigned if the disability picture more nearly approximates the criteria for that rating. Otherwise the lower rating will be assigned. 38 C.F.R. § 4.7. All benefit of the doubt will be resolved in the Veteran's favor. 38 C.F.R. § 4.3. In general, all disabilities, including those arising from a single disease entity, are rated separately, and all disability ratings are then combined in accordance with 38 C.F.R. § 4.25. Pyramiding, the evaluation of the same disability, or the same manifestation of a disability, under different diagnostic codes, is to be avoided when rating a Veteran's service-connected disabilities. 38 C.F.R. § 4.14. It is possible for a Veteran to have separate and distinct manifestations from the same injury which would permit rating under several diagnostic codes, however, the critical element in permitting the assignment of several ratings under various diagnostic codes is that none of the symptomatology for any one of the conditions is duplicative or overlapping with the symptomatology of the other condition. See Esteban v. Brown, 6 Vet. App. 259, 261-62 (1994). Where entitlement to compensation has already been established and an increase in the disability rating is at issue, the present level of disability is of primary importance. Francisco v. Brown, 7 Vet. App. 55, 58 (1994). However, separate ratings may also be assigned for separate periods of time based on the facts found. Hart, supra. The relevant temporal focus for adjudicating an increased rating claim is on the evidence concerning the state of the disability from the time period one year before the claim was filed until VA makes a final decision on the claim. Id. See generally 38 U.S.C.A. § 5110(b)(2) . In this regard, the Board notes that an August 1985 rating decision, which was issued in September 1985, had granted service connection for right knee condition and assigned an initial 10 percent rating, effective February 28, 1995. The Veteran did not enter a notice of disagreement with respect to the initially assigned rating. Moreover, no additional evidence referable to the Veteran's right ankle was associated with the claims file within one year of the issuance of such decision. 38 C.F.R. § 3.156(b); Bond, supra. Thereafter, VA received the Veteran's current claim for an increased rating for her right knee disability on June 29, 2007. In determining the degree of limitation of motion, the provisions of 38 C.F.R. §§ 4.10, 4.40, and 4.45 are for consideration. See DeLuca v. Brown, 8 Vet. App. 202 (1995). The basis of disability evaluation is the ability of the body as a whole, or of the psyche, or of a system or organ of the body to function under the ordinary conditions of daily life including employment. 38 C.F.R. § 4.10. Disability of the musculoskeletal system is primarily the inability, due to damage or infection in parts of the system, to perform the normal working movements of the body with normal excursion, strength, speed, coordination and endurance. Functional loss may be due to the absence or deformity of structures or other pathology, or it may be due to pain, supported by adequate pathology and evidenced by the visible behavior in undertaking the motion. Weakness is as important as limitation of motion, and a part that becomes painful on use must be regarded as seriously disabled. 38 C.F.R. § 4.40. In Mitchell v. Shinseki, 25 Vet. App. 32 (2011), the Court held that, although pain may cause a functional loss, "pain itself does not rise to the level of functional loss as contemplated by VA regulations applicable to the musculoskeletal system." Rather, pain may result in functional loss, but only if it limits the ability "to perform the normal working movements of the body with normal excursion, strength, speed, coordination, or endurance." Id., quoting 38 C.F.R. § 4.40. With respect to joints, in particular, the factors of disability reside in reductions of normal excursion of movements in different planes. Inquiry will be directed to more or less than normal movement, weakened movement, excess fatigability, incoordination, pain on movement, swelling, deformity or atrophy of disuse. 38 C.F.R. § 4.45. The intent of the Rating Schedule is to recognize actually painful, unstable or malaligned joints, due to healed injury, as entitled to at least the minimum compensable rating for the joint. 38 C.F.R. § 4.59. In Burton v. Shinseki, 25 Vet. App. 1, 5 (2011), the Court found that, when 38 C.F.R. § 4.59 is raised by the claimant or reasonably raised by the record, even in non-arthritis contexts, the Board should address its applicability. The February 2008 rating decision continued the Veteran's 10 percent disability rating for her degenerative joint disease of the knee, evaluated under 38 C.F.R. § 4.71a, Diagnostic Code 5010-5260. During the pendency of the appeal, a May 2009 rating decision granted a temporary evaluation of 100 percent under 38 C.F.R. § 4.30 based on surgical treatment necessitating convalescence, effective from June 16, 2008, to July 31, 2009. The May 2009 rating decision then granted the Veteran a 30 percent rating effective August 1, 2009, under 38 C.F.R. § 4.71a, Diagnostic Code 5010-5055. In the instant case, for the period prior to June 16, 2008, the hyphenated diagnostic code in this case indicates that the service-connected disability is considered to be traumatic arthritis (5010) associated with a residual condition of limitation of flexion (5260). See 38 C.F.R. § 4.27. For the period as of August 1, 2009, the hyphenated diagnostic code in this case indicates that the service- connected disability is considered to be traumatic arthritis (5010) associated with a residual condition of knee replacement (prosthesis) (5055). Id. Diagnostic Code 5010 provides ratings for arthritis due to trauma, substantiated by X-ray findings; it states to rate it as degenerative arthritis, Diagnostic Code 5003. Such provides that degenerative arthritis established by X-ray findings will be rated on the basis of limitation of motion under the appropriate diagnostic code(s) for the specific joint(s) involved. 38 C.F.R. § 4.71a, Diagnostic Code 5003. When, however, the limitation of motion of the specific joint(s) involved is noncompensable under the appropriate diagnostic code(s), a 10 percent rating is for application for each such major joint or group of minor joints affected by limitation of motion, to be combined, not added under Diagnostic Code 5003. Limitation of motion must be objectively confirmed by findings such as swelling, muscle spasm or satisfactory evidence of painful motion. In the absence of limitation of motion, a 10 percent rating is warranted if there is X- ray evidence of involvement of two or more major joints or two or more minor joint groups and a 20 percent rating is authorized if there is X-ray evidence of involvement of two or more major joints or two or more minor joint groups and there are occasional incapacitating exacerbations. 38 C.F.R. § 4.71a , Diagnostic Code 5003. Normal range of knee motion is 140 degrees of flexion and zero degrees of extension. 38 C.F.R. § 4.71 , Plate II. Limitation of motion of the knee is contemplated in 38 C.F.R. § 4.71a, Diagnostic Codes 5260 and 5261. Diagnostic Code 5260 provides for a zero percent rating where flexion of the leg is only limited to 60 degrees. For a 10 percent rating, flexion must be limited to 45 degrees. For a 20 percent rating is warranted where flexion is limited to 30 degrees. A 30 percent rating may be assigned where flexion is limited to 15 degrees. Diagnostic Code 5261 provides for a zero percent rating where extension of the leg is limited to five degrees. A 10 percent rating requires extension limited to 10 degrees. A 20 percent rating is warranted where extension is limited to 15 degrees. A 30 percent rating may be assigned where the evidence shows extension limited to 20 degrees. For a 40 percent rating, extension must be limited to 30 degrees. And finally, where extension is limited to 45 degrees a 50 percent rating may be assigned. 38 C.F.R. § 4.71a, Diagnostic Code 5257 provides for assignment of a 10 percent rating when there is slight recurrent subluxation or lateral instability, a 20 percent rating when there is moderate recurrent subluxation or lateral instability, and a 30 percent evaluation for severe recurrent subluxation or lateral instability. VA's General Counsel has stated that when a knee disorder is rated under 38 C.F.R. § 4.71a, Diagnostic Code 5257 and an appellant also has limitation of knee motion which at least meets the criteria for a noncompensable evaluation under 38 C.F.R. § 4.71a, Diagnostic Code 5260 or 5261, separate evaluations may be assigned for arthritis with limitation of motion and for instability. However, General Counsel stated that if an appellant does not meet the criteria for a noncompensable rating under either Diagnostic Code 5260 or Diagnostic Code 5261, there is no additional disability for which a separate rating for arthritis may be assigned. VAOPGCPREC 23-97 (July 1, 1997), published at 62 Fed. Reg. 63,604 (1997). If a rating is assigned under the provisions for other knee impairment (38 C.F.R. § 4.71a, Code 5257) a separate 10 percent rating may be assigned where some limitation of motion, albeit noncompensable, has been demonstrated. See VAOPGCPREC 9-98, 63 Fed. Reg. 56,704 (1998). VA's General Counsel has also stated that separate ratings under Diagnostic Code 5260 (limitation of flexion of the leg) and Diagnostic Code 5261 (limitation of extension of the leg) may be assigned for disability of the same joint. VAOPGCPREC 9-04 (September 17, 2004), published at 69 Fed. Reg. 59,990 2004). The rating schedule also provides that dislocation of semilunar cartilage, with frequent episodes of "locking," pain, and effusion into the joint, warrants a 20 percent evaluation. 38 C.F.R. § 4.71a , Diagnostic Code 5258. Diagnostic Code 5259 provides for the assignment of a maximum 10 percent rating based on symptomatic removal of the semilunar cartilage. Under Diagnostic Code 5055, for one year following implantation of a knee prosthesis for service-connected knee disability, a 100 percent rating is assigned. Thereafter, a 60 percent rating is assigned when there are chronic residuals consisting of severe painful motion or weakness in the affected extremity; or, a minimum 30 percent rating is assigned. When there are intermediate degrees of residual weakness, pain, or limitation of motion, these intermediate residuals are to be rated by analogy under 38 C.F.R. § 4.71a, Diagnostic Codes 5256, 5261, or 5262. See 38 C.F.R. § 4.71a, Diagnostic Code 5055. Private treatment records dated in June 2007 reflect complaints of pain, stiffness, and swelling. Upon physical examination, there was no skin abnormalities, swelling, or effusion. The alignment revealed mild valgus. There was tenderness over the lateral joint line on palpation. Range of motion was normal and all ligaments were stable. Strength was 5/5 and sensation, vascular, and gait were all normal. X-rays demonstrated severe osteoarthritis of the lateral compartment of the right knee. The Veteran was afforded a VA examination in July 2007 at which time she complained of pain all day every day, stiffness, locking, instability, and swelling. She denied flare ups. The Veteran indicated that she had a surgery for a meniscus tear and two arthroscopic surgeries to further debride cartilage. She also had many injections in the right knee with minimal improvement, multiple rounds of physical therapy, and currently took Mobic and Vicodin for pain. The Veteran reported that she was employed as a teacher but she could not use the stairs and she had to have a special parking spot. She also has missed work secondary to severe knee pain and for medical appointments. It was noted that she used a cane at times to aid in ambulation. On examination, the Veteran's range of right knee motion was full extension to 0 degrees and flexion was to 120 degrees. She had pain throughout the entire range of motion, but she was able to repetitively range the right knee without changing her range of motion or in her level of pain. The examiner found that the Veteran's range of motion measured was not additionally limited following repetitive use on examination. She had significant crepitus in the knee and it was diffusely tender to palpation with a slight effusion in the knee. She had exquisite tenderness to palpation over her anserine bursa. There was no significant warmth or erythema of the knee. Since the Veteran had significant pain in her knee with minimal manipulation, the McMurray's test was not performed; however, her Lachman's test, anterior drawer test, and posterior drawer test were normal. Her knee was stable to varus and valgus stressing. Plain films revealed moderate to severe degenerative joint disease of the right knee. Private treatment records dated in October 2007, January 2008, and June 2008 reflect that, upon examination, there was no skin abnormalities, swelling, or effusion. The alignment revealed mild valgus. There was tenderness over the lateral joint line on palpation. Range of motion was normal and all ligaments were stable. On June 16, 2008, the Veteran underwent surgery for a total knee replacement of the right knee. In July 2008, it was noted that she was attending physical therapy and progressing well. Upon examination, there was mild swelling of the right knee and range of motion was from zero to 104 degrees. Strength was 4+/5. Sensation and vascular examinations were normal. X-rays revealed an intact total knee prosthesis with good alignment and no evidence of loosening or failure. In August 2008 and September 2008, it was again noted that the Veteran was attending physical therapy and progressing well. Upon examination, there was mild swelling. Alignment was normal. Range of motion was zero to 120 degrees. All ligaments were stable. Strength was 5-/5. Sensation and vascular examinations were normal. In November 2008, it was noted that the Veteran had no knee pain with walking or range of motion. Upon examination in November 2008 and January 2009, there was no swelling or effusion. Alignment was normal. Range of motion was zero to 120 degrees. All ligaments were stable. Strength was 5- /5. Sensation and vascular examinations were normal. A March 2009 record reflects that the Veteran was status-post right total knee arthroplasty was doing well until that morning when she sustained a varus type injury to her right knee. She complained of pain. Upon examination, alignment was normal. There was tenderness to palpation about the lateral cruciate ligament. Range of motion was from zero to 120 degrees. All ligaments were stable. Strength was 5-/5. Sensation and vascular examinations were normal. In an August 2009 letter, the Veteran's private physician stated that she had five surgeries over the past several years, including a total knee replacement to the right knee last year. At the Veteran's September 2009 VA examination, she reported pain and swelling but no locking or instability. It was noted that she was not currently employed. Her most recent work was as a schoolteacher, but her occupation was affected because she could not move up and down stairs, could not sit or stand for long periods of time, and had difficulty getting to a sitting position. As a schoolteacher, such was an impossible combination. It was further observed that the Veteran's activities of daily living were affected in that she cannot go up and down steps and had to use a ramp at all times. She also had problems walking for more than 50 yards. The Veteran did not have flare-ups; rather, she had problems all of the time. She also used a can to help steady herself when she is walking. Upon examination, the Veteran's range of right knee motion was from 0 degrees to 100 degrees with pain throughout the range of motion and on palpation in any manner. There was no change in range of motion after repeated motion. The Lachman's test, McMurray test, drawer test, varus test, and valgus tests were abnormal bilaterally. The examiner noted that it was very difficult to perform a complete evaluation in such respect because of the pain on palpation of the knee. There was swelling and pain of both knees and sufficient palpation to adequately perform the test was impossible without causing undue pain. No crepitation was detected. The Veteran was diagnosed with degenerative joint disease, total knee replacement, and decreased range of motion of the right knee. November 2010 and May 2011 private treatment records reflect that the Veteran was status post bilateral total knee arthroplasty and was doing well. Upon examination of the right knee, the alignment was normal and there was no tenderness to palpation. Range of motion was zero to 115 degrees. All ligaments were stable and strength, sensation, and vascular examinations were normal. At the Veteran's June 2012 VA examination, she reported that, since her total knee replacement four years prior, she had intermittent issues with her knee but overall her knee worked well. She had 50 percent pain relief after her total knee replacement but she had some pain when she walked longer distances. She reported no flare-ups that impacted the function of her knee. The Veteran's range of motion for flexion was to 100 degrees and extension was 0 degrees with no objective evidence of painful motion. There was no change in range of motion after repetitive use. The only functional loss was less movement than normal and pain on movement. Muscle strength testing was 5/5 on knee flexion and extension. Lachman test, posterior drawer test, and medial-lateral instability testing revealed normal stability in the right knee. There was no evidence or history of recurrent patellar subluxation/dislocation. It was observed that the Veteran had previously had a meniscal tear and underwent a meniscectomy of both knees. She had no residual signs and/or symptoms due to the meniscectomy. The Veteran's total knee replacement residuals were described as intermediate degrees of residual weakness, pain, or limitation of motion. She occasionally used a wheelchair and a cane. There was no degenerative or traumatic arthritis documented on diagnostic testing. The examiner noted that the Veteran's knee conditions impacted her ability to work in that she had to quit work because she taught at a private school that was not handicap accessible and she could not do the job. Prior to June 16, 2008 Prior to the Veteran's right knee replacement surgery on June 16, 2008, she was assigned a 10 percent disability rating under Diagnostic Code 5010-5260. After a careful review of the evidence of record, the Board finds that prior to June 16, 2008, the Veteran's right knee disability does not warrant a rating in excess of 10 percent based upon painful, limited motion. However, the Board finds that her right knee disability does warrant a separate 20 percent disability rating under Diagnostic Code 5258 based on dislocation of semilunar cartilage, with frequent episodes of "locking," pain, and effusion into the joint. While Diagnostic Code 5003 provides a maximum 20 percent evaluation with X-ray evidence of involvement of 2 or more major or minor joints and occasional incapacitating episodes, the Veteran's service-connected disability clearly affects only one major joint: the right knee. Thus, an increased rating is not warranted under Diagnostic Code 5003 at anytime during the claims period. In order for the Veteran to warrant a higher rating based on limitation of motion there needs to be evidence of range of motion of flexion limited to 30 degrees (Diagnostic Code 5260) or extension limited to 10 degrees (Diagnostic Code 5261). However, at the Veteran's July 2007 VA examination her range of motion for flexion was to 120 degrees and her range of motion for extension was to 0 degrees, with pain. Her range of motion was not further limited following repetitive use. Thus, the Veteran's range of motion was normal for extension and range of motion for flexion does not meet the criteria for a compensable rating, even in contemplation of her complaints of pain throughout range of motion testing and upon repetitive motion testing; therefore, she does not warrant a higher rating under Diagnostic Codes 5260 or 5261. See DeLuca, Mitchell, supra. In this regard, a higher rating is not warranted unless it actually results in additional functional loss. See Mitchell, 25 Vet. App. at 38-43; DeLuca, 8 Vet. App. at 204- 7. Moreover, the evidence of record fails to demonstrate that the Veteran has extension of the right knee limited to a compensable degree and, therefore, separate ratings for limited flexion and extension are not warranted. See VAOPGCPREC 9-04. With regard to giving proper consideration to the effects of pain in assigning a disability rating, as well as the provisions of 38 C.F.R. § 4.45 and the holdings in DeLuca and Mitchell, supra, the reports from the examination and treatment records document consideration of these principles, and there is no indication that increased compensation would be warranted under these principles as such factors do not result in functional loss that more nearly approximates flexion or extension limited to a compensable degree. In reaching this conclusion, the Board has considered the Veteran's subjective complaints of pain, stiffness, locking, swelling, and instability, and objective evidence of tenderness, effusion, and crepitus; however, such do not result in additional functional loss. The Board has also considered whether the Veteran is entitled to a separate rating under Diagnostic Code 5257; however, the Board finds no objective evidence of subluxation or instability in the right knee. In this regard, the Board acknowledges that, at her July 2007 VA examination, the Veteran reported that she experiences some instability; however, as a layperson, she is not competent to diagnose internal instability or subluxation. In this regard, while she is competent to report that her knee feels unstable, there is no indication that she possesses the requisite knowledge to administer or interpret specialized testing that would reveal instability or subluxation. See Woehlaert v. Nicholson, 21 Vet. App. 456 (2007) (although the claimant is competent in certain situations to provide a diagnosis of a simple condition such as a broken leg or varicose veins, the claimant is not competent to provide evidence as to more complex medical questions). In this regard, the VA examiner, a medical professional, found that there Lachman's test, anterior drawer test, and posterior drawer test were normal and her knee was stable to varus and valgus stressing. Based on the foregoing, the objective medical evidence shows that the Veteran's right knee is stable without instability or subluxation. Accordingly, a separate rating for instability or subluxation of the right knee under Diagnostic Code 5257 is not warranted in this case. Although an increased or separate rating is not warranted under Diagnostic Codes 5003, 5257, 5260, or 5261 the Board finds that the Veteran's right knee disability most nearly approximates the criteria contemplated by Diagnostic Code 5258 and a separate rating of 20 percent is warranted. Under Diagnostic Code 5258, a maximum 20 percent evaluation is possible for dislocated semilunar cartilage, with frequent episodes of "locking," pain, and effusion. 38 C.F.R. § 4.71a, Diagnostic Code 5258. At the July 2007 VA examination, the McMurray test could not be administered and it was specifically noted that she had "locking", pain, and slight effusion. It was also reported that she had surgery for a meniscus tear and cartilage debridement. Thus, the Board finds that the Veteran meets the criteria for a separate 20 percent disability rating under Diagnostic Code 5258. The Board notes that Diagnostic Code 5258 does not on its face contemplate limitation of motion. In addition, while VA's General Counsel has held that Diagnostic Code 5259 (pertaining to removal of the semilunar cartilage) may contemplate limitation of motion, it has never addressed whether Diagnostic Code 5258 for dislocation of the cartilage similarly encompasses limited motion of the knee. In any event, the Board finds that in this case, the Veteran's service-connected right knee disability based on arthritis and painful, limited motion is not contemplated by Diagnostic Code 5258. Therefore the award of a separate evaluation is not deemed to be pyramiding. See 38 C.F.R. § 4.14; Esteban, supra. Additionally, as the evidence of record fails to demonstrate ankylosis, impairment of the tibia or fibula, or genu recurvatum, the Veteran is not entitled to a higher or separate rating under Diagnostic Codes 5256, 5262, or 5263, respectively. In sum, the Board finds that prior to June 16, 2008, the Veteran does not warrant an increased rating in excess of 10 percent based on painful, limited motion with arthritis since her range of motion. However, the Board finds that, prior to June 16, 2008, a separate 20 percent rating is warranted based on dislocated semilunar cartilage, with frequent episodes of "locking," pain, and effusion. Since August 1, 2009 In a May 2009 rating decision, the RO awarded the Veteran a temporary 100 percent disability rating based on convalesce for a right knee replacement as of June 16, 2008, and granted a 30 percent rating, effective August 1, 2009. The Veteran has been rated as 30 percent disabled under 38 C.F.R. § 4.71a, Diagnostic Code 5010-5055. Under Diagnostic Code 5055, for one year following implantation of a knee prosthesis for service-connected knee disability, a 100 percent rating is assigned. In this regard, the Veteran was granted a 100 percent disability rating effective from June 16, 2008 to July 31, 2009. Thereafter, she was assigned a 30 percent rating, which is the minimum rating after a total knee replacement. In order for the Veteran to warrant a rating in excess of 30 percent, her right knee disability must be manifested by chronic residuals consisting of severe painful motion or weakness in the affected extremity, or result in intermediate degrees of residual weakness, pain, or limitation of motion rated by analogy to Diagnostic Codes 5256, 5261, or 5262. However, the evidence of record does not approximate any of the criteria necessary for a rating in excess of 30 percent. Initially, the Board finds that the Veteran's right knee status post total knee replacement does not result in severe painful motion or weakness. In this regard, private treatment records dated within the year after her surgery, reflect symptoms to include, mild swelling; range of motion from zero to 104, which increased to 120 degrees; strength 4+ to 5-/5; with normal alignment, stable ligaments, and normal sensation and vascular examinations. Moreover, in November 2008, the Veteran had no knee pain with walking or range of motion. Furthermore, while she reported pain and swelling at the September 2009 VA examination, her range of motion was from zero to 100 degrees with pain and was not further limited after repeated motion. Additionally, while Lachman's test, McMurray test, drawer test, varus test, and valgus tests were abnormal bilaterally, the examiner noted that it was very difficult to perform a complete evaluation in such respect because of the pain on palpation of the knee. In this regard, he noted that there was swelling and pain of both knees and sufficient palpation to adequately perform the test was impossible without causing undue pain. However, on examination in November 2010 and May 2011, alignment was normal and there was no tenderness to palpation. Range of motion was zero to 115 degrees. All ligaments were stable and strength, sensation, and vascular examinations were normal. Moreover, on VA examination in June 2012, the examiner specifically determined that the Veteran's post right knee replacement was manifested by intermediate degrees of residual weakness, pain, or limitation of motion. In addition, she reported that since her surgery she had 50 percent pain relief and only had intermittent issues. She also reported no flare-ups. Her range of motion was from 0 to 100 degrees with no pain and the only functional loss was less movement than normal and pain on movement. Therefore, the Board finds that the Veteran's right knee symptomatology does not result in chronic residuals consisting of severe, painful motion or weakness in the affected extremity at any time since August 1, 2009. With regard to giving proper consideration to the effects of pain in assigning a disability rating, as well as the provisions of 38 C.F.R. § 4.45 and the holdings in DeLuca and Mitchell, supra, the reports from the examination and treatment records document consideration of these principles, and there is no indication that increased compensation would be warranted under these principles as such factors do not result in functional loss. In reaching this conclusion, the Board has considered that though the Veteran reported no pain there was objective evidence of pain on motion; however, there is no evidence of additional functional loss. As indicated previously, when there are intermediate degrees of residual weakness, pain or limitation of motion, the knee is to be rated by analogy to Diagnostic Codes 5256, 5261 or 5262. 38 C.F.R. § 4.71a. Diagnostic Code 5256 applies when there is evidence of ankylosis of the knee; however, the evidence of record clearly reflects that the Veteran does not suffer from ankylosis of the knee as she has been able to maintain significant motion of the knee throughout the appeal period. In addition, since her total knee replacement, her range of motion for extension has been normal (0 degrees) and thus, a higher rating is not warranted under Diagnostic Code 5261. Regarding Diagnostic Code 5262, such pertains to impairment of the tibia and fibula; however, such an impairment has not been alleged or shown in the instant case. Therefore, Diagnostic Codes 5256, 5261, and 5262 are not for application in this case. Other Considerations For the entire appeal period, the Board has carefully reviewed and considered the Veteran's statements regarding the severity of her right knee disability. The Board acknowledges that the Veteran, in advancing this appeal, believes that the disability on appeal has been more severe than the assigned disability rating reflects. Moreover, the Veteran is competent to report observable symptoms. Layno v. Brown, 6 Vet. App. 465 (1994). In this case, however, the competent medical evidence offering detailed specific specialized determinations pertinent to the rating criteria are the most probative evidence with regard to evaluating the pertinent symptoms for the disability on appeal; the medical evidence also largely contemplates the Veteran's descriptions of symptoms. The lay testimony has been considered together with the probative medical evidence clinically evaluating the severity of the pertinent disability symptoms. The Board further observes that the Veteran has scarring of the right knee as a result of her numerous surgeries. She has already been service-connected for such scarring for the entire appeal period, evaluated as noncompensably disabling, effective June 16, 2008. In this regard, the Board notes that such scarring is asymptomatic and not of a size to warrant a compensable rating. The Board has considered whether staged ratings under Hart, supra, in addition to those already assigned, are appropriate for the Veteran's service-connected right knee disability; however, the Board finds that her symptomatology has been stable throughout the appeal period. Therefore, assigning additional staged ratings for such disability is not warranted. Additionally, the Board has contemplated whether the case should be referred for extra-schedular consideration. An extra-schedular disability rating is warranted if the case presents such an exceptional or unusual disability picture with such related factors as marked interference with employment or frequent periods of hospitalization that application of the regular schedular standards would be impracticable. 38 C.F.R. § 3.321(b)(1). In Thun v. Peake, 22 Vet. App. 111, 115-16 (2008), the Court explained how the provisions of 38 C.F.R. § 3.321 are applied. Specifically, the Court stated that the determination of whether a claimant is entitled to an extra- schedular rating under § 3.321 is a three-step inquiry. First, it must be determined whether the evidence presents such an exceptional disability picture that the available schedular evaluations for that service-connected disability are inadequate. In this regard, the Court indicated that there must be a comparison between the level of severity and symptomatology of the claimant's service-connected disability with the established criteria found in the rating schedule for that disability. Under the approach prescribed by VA, if the criteria reasonably describe the claimant's disability level and symptomatology, then the claimant's disability picture is contemplated by the rating schedule, the assigned schedular evaluation is, therefore, adequate, and no referral is required. Second, if the schedular evaluation does not contemplate the claimant's level of disability and symptomatology and is found inadequate, the RO or Board must determine whether the claimant's exceptional disability picture exhibits other related factors such as "marked interference with employment" and "frequent periods of hospitalization." Third, when an analysis of the first two steps reveals that the rating schedule is inadequate to evaluate a claimant's disability picture and that picture has attendant thereto related factors such as marked interference with employment or frequent periods of hospitalization, then the case must be referred to the Under Secretary for Benefits or the Director of the Compensation and Pension Service to determine whether, to accord justice, the Veteran's disability picture requires the assignment of an extra- schedular rating. Id. The Board has carefully compared the level of severity and symptomatology of the Veteran's service-connected right knee disability with the established criteria found in the rating schedule. The Board finds that the Veteran's symptomatology is fully addressed by the rating criteria under which such disability is rated. In this regard, the Veteran's disability ratings contemplate her functional limitations caused by her right knee disability, to include painful, limited motion with arthritis and dislocated semilunar cartilage prior to June 16, 2008, and all residuals of her total knee replacement as of August 1, 2009. There are no additional symptoms of her right knee disability that are not addressed by the rating schedule. Therefore, the Board finds that the rating criteria reasonably describe the Veteran's disability level and symptomatology of her service-connected disability. As such, the Board finds that the rating schedule is adequate to evaluate the Veteran's disability picture. Therefore, the Board need not proceed to consider the second factor, viz., whether there are attendant thereto related factors such as marked interference with employment or frequent periods of hospitalization. Consequently, the Board concludes that referral of this case for consideration of an extra- schedular rating is not warranted. Id; Bagwell v. Brown, 9 Vet. App. 337, 338-39 (1996); Floyd v. Brown, 9 Vet. App. 88, 96 (1996). As indicated in the Introduction, in Rice, supra, the Court held that a claim for a TDIU is part of an increased rating claim when such claim is expressly raised by the Veteran or reasonably raised by the record. However, as the Veteran's TDIU claim is being remanded for additional development, no further discussion of such is necessary at this time. In sum, the Board finds that a separate rating of 20 percent for dislocated semilunar cartilage of the right knee is warranted for the appeal period prior to June 16, 2008. The Board, however, finds that the preponderance of the evidence is against the Veteran's claim for a rating in excess of 10 percent for degenerative joint disease of the right knee prior to June 16, 2008, and in excess of 30 percent for degenerative joint disease of the right knee, post total right knee replacement, as of August 1, 2009. In denying such ratings, the Board finds the benefit of the doubt doctrine is not applicable. 38 U.S.C.A. § 5107; 38 C.F.R. §§ 4.3, 4.7. ORDER For the appeal period prior to June 16, 2008, a rating in excess of 10 percent for degenerative joint disease of the right knee is denied. For the appeal period prior to June 16, 2008, a separate 20 percent rating, but no higher, for dislocated semilunar cartilage of the right knee is granted, subject to the laws and regulations controlling disbursement of VA monetary benefits. For the appeal period since August 1, 2009, a rating in excess of 30 percent for degenerative joint disease of the right knee, post total right knee replacement, is denied. REMAND As indicated in the Introduction, when evidence of unemployability is submitted during the course of an appeal from an assigned disability rating, a claim for a TDIU will be considered part and parcel of the claim for benefits for the underlying disability. See Rice, supra. Here, such issue has been raised in the context of her claim for an increased rating for her right knee disability. Specifically, at the Veteran's September 2009 VA examination, it was noted that she was not currently employed. Her most recent work was as a schoolteacher, but her occupation was affected because she could not move up and down stairs, could not sit or stand for long periods of time, and had difficulty getting to a sitting position. As a schoolteacher, such was an impossible combination. Additionally, the June 2012 VA examiner noted that the Veteran's knee conditions impacted her ability to work in that she had to quit work because she taught at a private school that was not handicap accessible and she could not do the job. However, the Board finds that further development is necessary for a fair adjudication of the Veteran's TDIU claim. In this regard, upon remand, the AOJ should conduct all appropriate development, to include providing the Veteran with VCAA-compliant notice as to a TDIU, obtaining outstanding treatment records, and obtaining an opinion regarding the effect the Veteran's service-connected disabilities, to include her right knee disability, has on her employability. See Friscia v. Brown, 7 Vet. App. 294, 297 (1994). Accordingly, the case is REMANDED for the following action: 1. The Veteran should be provided with proper VCAA notice regarding the evidence and information necessary to substantiate her TDIU claim. She should also be requested to complete and return VA Form 21-8940 (Veteran's Application for Increased Compensation Based on Unemployability). 2. The Veteran should be given an opportunity to identify any healthcare provider who treats her for her service- connected disabilities. After securing any necessary authorization from her, obtain all identified treatment records. All reasonable attempts should be made to obtain such records. If any records cannot be obtained after reasonable efforts have been made, issue a formal determination that such records do not exist or that further efforts to obtain such records would be futile, which should be documented in the claims file. The Veteran must be notified of the attempts made and why further attempts would be futile, and allowed the opportunity to provide such records, as provided in 38 U.S.C.A. § 5103A(b)(2) and 38 C.F.R. § 3.159(e) . 3. After completing the above, the claims file should be forwarded to an appropriate medical profession to offer an opinion as to whether the Veteran's service-connected disabilities render her unemployable. The claims file and a copy of this Remand must be made available to the examiner, and the examiner shall indicate in the report that the claims file was reviewed. The need for an additional examination of the Veteran is left to the discretion of the examiner selected to write the opinion. Following a review of the record, the examiner should render an opinion as to whether the Veteran is unable to secure or follow a substantially gainful occupation as a result of her service-connected disabilities, either singularly or jointly, taking into consideration her level of education, special training, and previous work experience, but not his age or any impairment caused by nonservice- connected disabilities. In this regard, the Veteran is service-connected for PTSD; degenerative joint disease, status post total knee arthroplasty, of the right knee; degenerative joint disease, status post total knee arthroplasty, of the left knee; and residual scarring of the knees. The examiner should specifically consider the findings noted at the September 2009 and June 2012 VA examinations regarding the impact her knee conditions have on her ability to work as a schoolteacher. All opinions offered should be accompanied by a rationale. 4. After completing the above, and any other development as may be indicated by any response received as a consequence of the actions taken in the preceding paragraphs, the Veteran's claim should be readjudicated based on the entirety of the evidence. If the claim remains denied, the Veteran and her representative should be issued a supplemental statement of the case. An appropriate period of time should be allowed for response. Thereafter, the case should be returned to the Board for further appellate consideration, if otherwise in order. The Board intimates no opinion as to the outcome of this case. The Veteran need take no action until so informed. The purpose of this REMAND is to ensure compliance with due process considerations. The Veteran has the right to submit additional evidence and argument on the matter the Board has remanded. Kutscherousky v. West, 12 Vet. App. 369 (1999). This claim must be afforded expeditious treatment. The law requires that all claims that are remanded by the Board or by the United States Court of Appeals for Veterans Claims for additional development or other appropriate action must be handled in an expeditious manner. See 38 U.S.C.A. §§ 5109B, 7112 (West Supp. 2012). ______________________________________________ A. JAEGER Veterans Law Judge, Board of Veterans' Appeals Department of Veterans Affairs
