REPRESENTATION Appellant represented by: Mark R. Lippman, Attorney WITNESS AT HEARING ON APPEAL Appellant ATTORNEY FOR THE BOARD Robert A. Leaf, Counsel INTRODUCTION The veteran had active military service from January 1955 to April 1977. This long-standing claim comes before the Board of Veterans' Appeals (Board) on appeal from the St. Petersburg, Florida, Department of Veterans Affairs (VA) Regional Office (RO). The long procedural history of the case can be summarized as follows: ? February 1989 - the RO denied the veteran's claim for a left hip disorder. This decision becomes final one year later. ? October 1991 - RO denies the veteran's claim for a left hip disorder based on new and material evidence. The veteran appeals this decision to the Board. ? December 1995 - the Board remands the new and material claim for further development. ? September 1998 - the Board finds that that no new and material evidence has been submitted and denies the claim to reopen. ? Veteran appeals to the United States Court of Appeals for Veterans Claims (Veterans Claims Court). ? March 1999 - the Veterans Claims Court vacates the Board's September 1998 decision and remands the claim due to a change in the new and material evidence law. See Hodge v. West, 155 F.3d 1356 (Fed. Cir. 1998). ? September 1999 - the Board reopens the claim based on new and material evidence and remands the claim to the RO for further development, including a VA examination and medical opinion on aggravation. ? May 2000 - the Board denied the veteran's claim for entitlement to service connection on the merits. ? Veteran appeals to the Veterans Claims Court. ? January 2001 - the Veterans Claims Court vacated the Board's May 2000 decision. ? February 2002 - the Board seeks further development under the provisions of 38 C.F.R. § 19.9 for pre-service medical records and a VA examination. ? October 2002 - the Board again denies the veteran's claim. ? Veteran appeals to the Veterans Claims Court. ? July 2003 - the Veterans Claims Court vacates the Board's October 2002 decision for readjudication in light of the Veterans Claims Assistance Act (VCAA). ? January 2004 - the Board remands the claim to the RO due to a change in the law no longer allowing the Board to issue VCAA letters under the provisions of 38 C.F.R. § 19.9. See Disabled American Veterans v. Secretary of Veterans Affairs, 234 F.3d 682 (Fed. Cir. 2003). ? February 2004 - VCAA letter issued to the veteran. ? February 2004 - the veteran indicates that he has no more evidence to submit. ? September 2004 - the Board issued a decision again denying the claim. ? Veteran appeals to the Veterans Claims Court. ? March 2005 - the Court issued an order vacating the Board's decision and remanding the case to the Board for further development and readjudication in compliance with instructions in a joint motion for remand (JMR). FINDINGS OF FACT 1. No left hip abnormality was noted when the veteran was examined for service in 1955; service medical evidence shows no more than three complaints related to the veteran's left leg/hip throughout his 22 year career; no left hip disorder was noted when he was examined prior to his retirement from service in April 1977. 2. Post-service, the veteran first sought treatment for left hip pain in 1985, 8 years after his retirement from service, and was diagnosed with DJD. He underwent a hip replacement in 1988. 3. While the veteran's own statements indicate that he was treated for a left hip disorder as a child and medical- judgment evidence suggests that the veteran suffered from likely Legg-Perthes disease as a child, there is no clear and unmistakable evidence demonstrating that the veteran had a chronic left hip disorder before he entered military service in January 1955. 4. The weight of the medical evidence establishes that the DJD of the veteran's left hip was first manifested more than one year after service and is not due to any injury suffered or disease contracted during military service. CONCLUSIONS OF LAW 1. A chronic left hip disorder did not clearly and unmistakably pre-existed service; the presumption of soundness is not rebutted and the veteran's claim is one for service connection based on incurrence in service. 38 U.S.C.A. §§ 1110, 1111, 1153, 5103A, 5103(a) (West 2002); 38 C.F.R. §§ 3.303, 3.304 (2005); Wagner v. Principi, 370 F.3d 1089, 1096 (2004). 2. A chronic left hip disability was not incurred in military service and DJD of the left hip may not be presumed to have been incurred in service. 38 U.S.C.A. §§ 1101, 1110, 1111, 1112, 1113, 1131, 1154, 5103A, 5103(a) (West 2002); 38 C.F.R. §§ 3.303, 3.304, 3.306, 3.307, 3.309 (2005). REASONS AND BASES FOR FINDINGS AND CONCLUSION Procedural Due Process, Preliminary Duties to Notify and Assist. The Board notes that on November 9, 2000, the Veterans Claims Assistance Act of 2000 (VCAA) (codified at 38 U.S.C.A. § 5100 et seq.) became law. Regulations implementing the VCAA have been published. 38 C.F.R. §§ 3.102, 3.156(a), 3.159, 3.326(a). The veteran was notified of the VCAA as it applies to his present appeal by correspondence dated in February 2004. The Board finds that any defect with respect to the timing of the VCAA notice requirement was harmless error. While the notice provided to the veteran in February 2004 was not given prior to the first AOJ adjudication of the claim, the notice complied with the requirements of 38 U.S.C. § 5103(a) and 38 C.F.R. § 3.159(b). The issue on appeal was re-adjudicated and a supplemental statement of the case was provided to the veteran in June 2004. The veteran has been provided every opportunity to submit evidence and argument in support of his claim, and to respond to VA notices. The February 2004 VCAA notice letter provided to the veteran generally informed him of the evidence not of record that was necessary to substantiate his claim and identified which parties were expected to provide such evidence. The veteran was notified of the need to give to VA any evidence pertaining to his claim. In addition, 38 C.F.R. § 3.159(b)(1) was cited in the June 2004 supplemental statement of the case. Moreover, he was informed by letters dated in March 2002 and June 2002 that the claim was undergoing additional development and of his due process rights. In light of the actual notice provided, the Board finds that any content deficiency in the February 2004 notice letter was non-prejudicial error. All the VCAA requires is that the duty to notify be satisfied, and that claimants are given the opportunity to submit information and evidence in support of their claims. Once this has been accomplished, all due process concerns have been satisfied. See Bernard v. Brown, 4 Vet. App. 384 (1993); Sutton v. Brown, 9 Vet. App. 553 (1996); see also 38 C.F.R. § 20.1102 (harmless error). Here, because each of the content requirements of a VCAA notice has been fully satisfied, any error in not providing a single notice to the veteran covering all content requirements is harmless error. The revised VCAA duty to assist requires that VA make reasonable efforts to assist the claimant in obtaining evidence necessary to substantiate a claim. See 38 C.F.R. § 3.159. In this case, the veteran's service medical records and all identified and authorized post-service medical records relevant to the issue on appeal have been requested or obtained. In addition, he submitted two private medical opinions in support his claim, which have been carefully considered by the Board. In claims for disability compensation the VCAA duty to assist requires VA provide medical examinations or obtain medical opinions when necessary for an adequate decision. The Board notes that specific VA medical opinions pertinent to the issue on appeal were obtained in July 1996, October 1999, and May 2002. The available medical evidence is sufficient for adequate determinations. Therefore, the Board finds the duty to assist and duty to notify provisions of the VCAA have been fulfilled. Legal Criteria. Under the relevant regulations, service connection may be granted for a disability resulting from disease or injury incurred in or aggravated by active service. 38 U.S.C.A. §§ 1110, 1131 (West 2002). If a chronic disease is shown in service, subsequent manifestations of the same chronic disease at any later date, however remote, may be service connected, unless clearly attributable to intercurrent causes. 38 C.F.R. § 3.303(b) (2005). However, continuity of symptoms is required where the condition in service is not, in fact, chronic or where diagnosis of chronicity may be legitimately questioned. 38 C.F.R. § 3.303(b) (2005). Next, service connection may also be granted for any disease diagnosed after discharge, when all the evidence, including that pertinent to service, establishes that the disease was incurred in service. 38 U.S.C.A. § 1113(b) (West 2002); 38 C.F.R. § 3.303(d) (2005). In addition, where a veteran served ninety days or more during a period of war or during peacetime after December 31, 1946, and arthritis becomes manifest to a degree of 10 percent within one year of the date of termination of service, such disease shall be presumed to have been incurred in service, even though there is no evidence of such disease during the period of service. 38 U.S.C.A. §§ 1101, 1112, 1113 (West 2002); 38 C.F.R. §§ 3.307, 3.309 (2005) Every veteran shall be taken to have been in sound condition when examined, accepted, and enrolled for service, except as to defects, infirmities, or disorders noted at the time of the examination, acceptance, and enrollment, or where clear and unmistakable evidence demonstrates that the injury or disease existed before acceptance and enrollment and was not aggravated by such service. 38 U.S.C.A. § 1111; 38 C.F.R. § 3.304(b). To rebut the presumption of soundness, VA must find clear and unmistakable evidence of both a preexisting condition and a lack of in-service aggravation to overcome the statutory presumption of soundness for wartime service. VAOPGCPREC 3- 2003 (July 16, 2003); see also Wagner v. Principi, 370 F.3d 1089, 1096 (Fed.Cir.2004); Joyce v. Nicholson, 19 Vet. App. 36, 40 (2005); Cotant v. Principi, 17 Vet. App. 116, 123-30 (2003). The word "unmistakable" means that an item cannot be misinterpreted and misunderstood, i.e., it is undebatable. See WEBSTER'S NEW WORLD DICTIONARY 1461 3rd Coll. ed.1988); cf. Crippen v. Brown, 9 Vet. App. 412, 418 (1996) (stating that "clear and unmistakable error" means an error that is undebatable); Russell v. Principi, 3 Vet. App. 310 (1992) (en banc) ("The words 'clear and unmistakable error' are self- defining. They are errors that are undebatable, so that it can be said that reasonable minds could only conclude that the original decision was fatally flawed."). Vanerson v. West,12 Vet. App. 254, 258-259 (1999). Rebuttal of the presumption must involve an impartial and thorough review of all the evidence of record. The provisions of 38 C.F.R. § 3.304(b) direct VA adjudicators to consider all of the relevant evidence of record when determining whether clear and unmistakable evidence exists to rebut the presumption of soundness. See Crowe v. Brown, 7 Vet. App. 238, 245-46 (1994) ("In determining whether there is clear and unmistakable evidence that the injury or disease existed prior to service, the Court considers the history recorded at the time of examination together with 'all other material evidence.'") (quoting 38 C.F.R. § 3.304(b)(1)); Parker v. Derwinski, 1 Vet. App. 522, 524-25 (1991) (holding that the Board must analyze the medical opinions it was relying on to rebut the presumption of soundness "in the context of all the evidence of record," including the appellant's sworn testimony that the service medical doctor had misinterpreted his statement). The Court in Vanerson stated the following: Additionally, the standard of proof for rebutting the presumption of soundness is not merely evidence that is cogent and compelling, i.e., a sufficient showing, but evidence that is clear and unmistakable, i.e., undebatable . . . . [and] the question is not whether the Secretary has sustained a burden of producing evidence, but whether the evidence as a whole, clearly and unmistakably demonstrates that the injury or disease existed prior to service. That determination is dispositive as to the question of preservice inception; further adjudication under a preponderance of the evidence would be redundant. Vanerson, 12 Vet. App. at 261, as quoted in Cotant v. Principi, 17 Vet. App. 116, 132 (2003). The Board must determine whether the evidence supports the claim or is in relative equipoise, with the veteran prevailing in either case, or whether the preponderance of the evidence is against the claim, in which case, service connection must be denied. Gilbert v. Derwinski, 1 Vet. App. 49 (1990). Analysis. The veteran maintains that service connection is warranted for degenerative joint disease, which ultimately led to a hip replacement. He contends that he injured his left hip while in service when he fell and sustained an injury to his right ribs. He vigorously disagrees with several medical opinions finding a likelihood of Legg-Perthes disease prior to service and that degenerative arthritis of his left hip was due to the natural progression of the disease. Presumption of Soundness No pre-service medical records are available. In the February 2002 Board development, the veteran was asked to provide any information concerning medical treatment he received prior to military service. He related that one physician, who had performed a single home visit, had died in the 1950s or 1960s. He could not recall the name of another physician who had treated him in 1952-53 and the physician had apparently moved to Florida 30 years previously. The veteran's January 1955 entrance examination did not mention a pre-existing left hip disorder and his lower extremities were normal. For that reason, he is entitled to the presumption of soundness. While there is medical-judgment evidence and the veteran's own statements which indicate that he suffered from a pre- service left hip disorder, diagnosed as likely Legg-Perthes disease, the evidence regarding this matter is not clear and unmistakable. In a May 1985 report, the veteran related a long history of hip pain, which he stated began at childhood; however, he reported that his left hip had not bothered him during 22 years of active duty service. A leg length discrepancy was noted and an X-ray revealed avascular necrosis and collapse of a rather severe stage IV injury with involvement concomitantly of the acetabulum with post- traumatic arthrosis. In an April 1988 private medical record, the treating physician noted that the veteran related complaints of hip pain "to an old injury as a child when he fell off a bike." In May 1988, he underwent a left hip replacement. The preoperative diagnosis was severe degenerative arthritis of the left hip with acetabular and femoral head cystic changes. The examiner felt the condition was secondary to an old childhood injury, which was "probably Legg-Perthes disease, left hip." A July 1996 VA examination report reflect that after examining the veteran and reviewing the claims file, the VA examiner concluded that "it appears [the veteran] had Perthes disease of the left hip as a child." In an October 1999 VA examination report the same VA examiner stated that the medical records indicated an old injury to the left hip as a child with subsequent development of "probable Perthes disease." In a May 2002 VA examination report, another examiner noted that the lack of X-ray evidence confirming a diagnosis of Legg-Perthes in childhood spoke again the diagnosis of Legg- Perthes disease but stressed that the post-service X-ray evidence and clinical examination suggested that the veteran's left hip condition was, in fact, secondary to Legg- Perthes disease. Two reports of a private physician, submitted in support of the veteran's claim, appear to concede that the veteran experienced a pre-service hip injury. Of note, in a September 2001 report, the private physician stressed that the veteran's "Perthes' disease was aggravated and made worse" by military service. More recently, the same private physician remarked that the issue was properly characterized as whether military service aggravated the veteran's Legg- Perthes disease. This assertion, by definition, appears to concede the premise that the veteran had Legg-Perthes disease prior to military service. In several statements received in December 1999 and February 2000, the veteran took issue with an earlier reported medical history. He maintained that he had not injured his hip during childhood when he fell off a bike, but that he had injured the hip when he fell in 1964 during service. He also emphasized that probable arthritis was diagnosed during service. He contended that because the doctors made use of the words "probably" and "possibly," their reports were full of conjecture and speculation. To that end, the Board has considered the equivocal nature of the diagnoses of Legg Perthes disease (the use of terms such as "likely," "probable," etc.). While medical opinions, both VA and private, independently suggest that the veteran had Legg-Perthes disease as a child, the pre-service existence of this condition can not be ruled in or ruled out medically because no pre-service medical records are available. While the Veterans Claims Court has held that post-service medical judgment alone may be used to rebut the presumption of soundness as long as the evidence is clear and unmistakable, the evidence in this case as to the pre-service existence of Legg-Perthes disease is not clear and unmistakable. See Jordan v. Principi, 16 Vet. App. 335 (2002), withdrawn, 2002 WL 31445159 (Vet. App. Nov. 1, 2002); but see Jordan v. Principi, 17 Vet. App. 261, 280 (2003) (medical judgment may play a conclusive role in making presumption of soundness determination). In this case, the Board concludes that the medical evidence as to the pre- service existence of a chronic left hip disorder is somewhat equivocal in nature. Accordingly, the Board concludes that the presumption of soundness is not rebutted. Applying the presumption of sound condition results in a finding that the veteran entered service in sound condition and not in a determination that he is entitled to an award of service connection for a left hip disorder. Since the presumption of soundness is not rebutted by clear and unmistakable evidence, the veteran's claim is one for service connection based on incurrence in service. Wagner, 370 F.3d at 1096. Incurrence of Chronic Left Hip Disability During Service The veteran sought treatment for left leg/hip complaints on three occasions during his 22 years of military service. Specifically, in March 1958, he reported weakness in the extensor muscles of the left thigh after bowling. The impression was questionable hypochondriasis. In September 1958, he reported that his left leg felt weak and caused slight pain and cramps in the lower leg. The examiner stated that the muscle cramps had been occasional in the left calf for three to four days and that it was normal. Thereafter, service examinations dated in October 1958 and January 1959 showed normal clinical evaluations of the veteran's lower extremities. In July 1964, the veteran reported left knee and left hip pain. The clinical impression was "probable arthritis or rheumatoid involvement of knee and hip" but there is no indication of additional follow-up or treatment. Significantly, service examinations dated in January 1965, September 1965, June 1969, June 1974, April 1975, and August 1976, reflect a normal clinical evaluation of the veteran's lower extremities. Moreover, the service separation examination dated in March 1977 also showed a normal clinical evaluations of the veteran's lower extremities. While he reported complaints which could be related to his left hip in March 1958 (left thigh weakness), September 1958 (cramping and weakness in the lower left leg), and July 1964 (left knee and left hip pain), the Board places greater probative value on the absence of a chronic left hip disorder as evidenced by a normal clinical evaluation of the veteran's lower extremities in service examinations dated in October 1958, January 1959, January 1965, September 1965, June 1969, June 1974, April 1975, and August 1976. The Board also assigns greater probative value to the service separation examination dated in March 1977 showing a normal clinical evaluation of the veteran's lower extremities, particularly in light of multiple other disorders noted on the separation examination. Therefore, the Board finds no medical evidence of a chronic left hip disorder while he was on active duty. A finding that the veteran did not manifest a chronic left hip disorder during military service is also supported by the post-service medical evidence showing that he continued to be symptom-free for several years after service separation. Specifically, the Board has reviewed the post-service medical records associated with the claims file and finds no reference to left hip complaints until 1985, some 7 years after service separation. At that time, he related a long history of hip pain beginning in childhood. In April 1988, some 11 years after service separation, the veteran sought treatment for increasing pain in his left hip. The private physician reported that the veteran "relates this to an old injury as a child when he fell off a bike." In May 1988, he underwent a left hip replacement. The pre-operative diagnosis was severe degenerative arthritis of the left hip with acetabular and femoral head cystic changes. The private physician stated that he felt that the current diagnosis was secondary to an old childhood injury, which was probably Legg-Perthes disease, left hip. The Board finds the multi- year gap between service separation and treatment for left hip pain highly suggestive that the left hip disorder identified several years after service was not incurred during service. A July 1996 VA examination report reflects that the VA examiner attributed the degenerative disease of the veteran's left hip to the a left hip condition that the veteran had as a child, which the examiner stated appeared to be Perthes disease of the left hip, that slowly but progressively worsened over the years until the veteran eventually required a total hip replacement in 1988. The examiner did not suggest that DJD of the left hip was first manifested during service or was due to any injury suffered or disease contracted during military service. Similarly, an October 1999 VA examination report reflects that the VA examiner stated that the medical records indicated an old injury to the veteran's left hip as a child with subsequent development of probable Perthes disease which progressively worsen over the years until eventually severe degenerative disease had developed. The examiner stated that he believed that the increase in severity was compatible with the natural progression of the old Legg Perthes disease. He stated that the degeneration of the hip was slowly progressive and relentless over the years. The VA examiner reported that to say that the increase in severity was "beyond the natural progression" would require, to some degree, conjecture and speculation. The Board finds that there is nothing in this analysis that would support a finding that the veteran has a chronic left hip disorder that began during service or is due to any injury suffered or disease contracted during the veteran's military service. In a statement dated in September 2001, C. Bash, M.D., a Neuro-Radiologist, offered his opinion that the veteran's in- service complaints related to his legs/hips were evidence that the veteran's left hip DJD "was likely caused by his service experiences." Dr. Bash stated the following: In review of this patient's record it is clear that he visited had several visits (sic) to medical personnel for left leg complaints during service in 1958, 1958, 1964, 1977 and was observed with a limp by a real estate salesman in 1973. The record also documents that this patient was a welder and therefore was likely on his feet for extended periods of time while he was welding pieces of metal. * * * * It is my opinion that the patient's Perthes' disease was aggravated and made worse by his service physical requirements and his advanced DJD was likely caused by his service experiences because a large proportion of patients with this disease have mild symptoms and do not require a hip replacement. In a May 2002 VA examination report, the veteran related that he jumped from a bunk in 1958 but did not recall any injury. In 1962, reportedly he ejected in a seat but did not recall any injury. In 1964, he noted he fell on an aircraft and sustained fractured ribs but could not recall whether he complained of hip pain. He retired from the military in 1977, worked as a sheet metal worker for 17 years and retired in 1995. The examiner noted that the veteran first complained of hip pain in 1985 and was diagnosed with arthritis and underwent a left hip arthroplasty in 1988 and a revision in 2000. With respect to the veteran's Legg-Perthes disease, the examiner noted that it was a disease of the head of the femur occurring more in males than females and generally having its onset between the ages of three and eight. It resulted in loss of circulation to the bone of the head of the femur and subsequent deformity of the femur head. It could occur with significant symptoms or hardly any symptoms at all. The etiology was unknown. The diagnosis was made by X-ray as well as ruling out other conditions which may present with similar findings such as hypothyroidism and epiphyseal dysplasia. Thirty to forty percent of the children with this condition had a persistent deformity of the head of the femur into adulthood, presenting with the signs and symptoms of arthritis, which could require corrective surgery. The examiner noted that if the veteran had had a bicycle fall as a child, it could have contributed to the deformity of an already diseased femoral head. He noted that the lack of X- ray evidence as a child spoke against the diagnosis of Legg- Perthes disease but the findings on X-ray and clinical examinations prior to hip surgery suggesting that his condition was secondary to Legg-Perthes disease spoke in favor of the condition. He was unable to determined the date on which the Legg-Perthes disease had its onset. The examiner reflected that the record did not indicate that Legg-Perthes disease, if it existed, progressed at an abnormally high rate during the veteran's military service. He noted only three references to complaints related to the veteran's left hip in July 1964, September 1958, and March 1958, during the veteran's 22 years of active duty. He opined that this spoke against any abnormally high rate of progress of the disease during the veteran's military duty. The examiner reflected that since Legg-Perthes disease, by definition, had its onset in early childhood, there was no probability of its having its onset during military service. He noted that one may speculate that the osteoarthritis for which the veteran required surgery in 1988 may have had its onset in service but that this was not supported by the record. He concluded that the medical opinions were expressed after questioning the veteran and examining him and the record and were as unequivocal as medical probability would allow. In a July 2002 follow-up letter, Dr. Bash stated his opinion that the May 2002 VA medical opinion that the veteran's osteoarthritis did not have its onset in service was "illogical and clearly wrong." Dr. Bash stated that "three documented visits for hip problems during service, that by definition is onset, therefore the record does support the concept that [the veteran's] hip was made worse or worsened during service-time." In his statement of July 2002, Dr. Bash stated the following: In summary it is not speculation that this patients (sic) osteoarthritis development and or was made worse by his military service and that this arthritis lead (sic) directly to his need for hip replacement for the following reasons: 1. the patient had several visits to medical personnel for hip problems during service. 2. the patient had a physically demanding job in service, which required several hours a day of work on his feet as a welder. 3. the literature supports as (sic) association between stress (standing -repetitive trauma) across the hip articulation and the development of joint degeneration (osteoarthritis). . . . It is as likely as not (50-50 chance) that this patient's Perth's (sic) disease was made worse during his service time due to the physical demands of his service experience. The Board finds that Dr. Bash's assessment is not consistent with the service medical records. Dr. Bash stressed that the veteran "had three documented visits for hip problems during service, that by definition is onset, therefore the record does support the concept that [the veteran's] hip was made worse or worsened during service- time." The Board does not agree. First, the service medical records do not support the proposition that the veteran sought treatment for hip complaints on three occasions. In March 1958, he reported left thigh weakness but no diagnosis was made related to the hip. In September 1958, he reported cramping and weakness in the lower left leg. Although it could be construed as referred pain, the military examiner made no mention of a hip problem. Finally, in July 1964, the veteran, for the first time, reported left knee and left hip pain but no specific diagnosis was made. Therefore, the in-service medical evidence does not necessarily reveal that the veteran sought treatment for hip pain on three occasions. Next, even if his in-service symptoms could be construed to be related to a left hip disorder, the Board places more probative value on the subsequent periodic service examinations reflecting a normal clinical evaluation of the veteran's lower extremities. This suggests that any in- service symptoms were acute and transitory. Therefore, the Board finds that three isolated complaints vaguely related to the veteran's left hip over a period of 22 years, without more, cannot establish the presence of a chronic left hip disorder. As such, the Board finds that the service medical records do not support a finding that a chronic left hip disorder was manifested during the veteran's military service. Moreover, Dr. Bash does not address the multi-year period between service separation and post-service hip complaints, during which time the veteran was essentially asymptomatic. Therefore, the Board places significantly less probative value on Dr. Bash's medical opinion as it is not consistent with the service medical records or with the post-service medical evidence showing no pertinent complaints or findings for several years after he was released from military service. After carefully weighing all three recent medical opinions, the Board is compelled to place more probative weight on the VA examination because it is consistent with the medical evidence of record. Specifically, the Board does not dispute the evidence that the veteran experienced signs and symptoms associated with his left leg/knee in service as this is reasonably supported by the service medical records showing complaints in March 1958, September 1958, and July 1964. However, as noted above, these complaints are not shown to be indicative of a chronic left hip disorder but rather are shown to have been acute and temporary as demonstrated by subsequent examinations. While the Board acknowledges Dr. Bash's opinion that a left hip disorder would have been aggravated by prolonged standing, his stressful job, and the like, a chronic left hip disorder is not shown to have been manifested during his period of military duty. To this end, the Board places greater probative weight on the service medical records, which clearly show that the clinical examinations of the veteran's lower extremities, including his separation examination, were normal throughout his 22- year military career. The Board has also considered the veteran's own statements that his left hip disorder was manifested during military service. His assertions are not deemed to be persuasive in light of the other objective evidence of record showing no chronic left hip impairment during service and no indications of pertinent symptoms for many years after military discharge. In the absence of competent, credible evidence of in-service left hip impairment, and no post-service treatment for several years after service separation, service connection for a chronic left hip disorder must be denied. Further, the veteran has alleged that Legg Perthes disease may have healed and that the fall he sustained in service could have re-injured his left hip. He has alleged various bases as to why service connection for degenerative joint disease, to include left hip replacement, is warranted. He refutes the medical findings made by the VA examiner that Legg Perthes disease pre-existed service and was not aggravated in service. However, it has not been shown that he possesses the requisite knowledge of medical principles that would permit him to render an opinion regarding matters involving medical diagnoses or medical etiology. See Espiritu v. Derwinski, 4 Vet. App. 492, 494 (1992). Moreover, the October 1999 VA examiner specifically addressed the issue of whether the veteran's hip was injured at the time of a 1964 fall (when he sustained a contusion to his right ribs). The examiner stated that there was no evidence to suggest that the veteran's left hip was injured at that time. He reflected that it was possible for the left hip to have been injured, but that the veteran had not recalled a hip injury. The VA examiner noted that the veteran asserted that the hip was only "possibly injured" in the fall. The VA examiner stated that to determine that the hip was injured would be resorting to conjecture and speculation. The Board places high probative value on the medical opinion as it directly addresses, but contradicts, the veteran's assertion. To the extent the veteran claims entitlement to benefits for a left hip disorder on a presumptive basis, the Board finds that the veteran's claim must fail. First, the Board is persuaded by the absence of complaints of, treatment for, or diagnosis of a chronic left hip disorder in service or until many years after his retirement from service. As noted, the service medical records are negative for degenerative joint disease of the left hip as evidenced by normal clinical examinations, although the records note "possible" arthritis, including rheumatoid arthritis, which has never again been suggested. Further, there are no complaints related to a left hip disorder for many years after service separation. As such, the Board finds no evidence of continuity of symptomatology as shown by the multi-year gap between service separation and treatment for a left hip disorder in 1988. Accordingly, the veteran's claim for a left hip disorder on a direct or presumptive basis must be denied. The service medical records reflect that the veteran was symptom-free at the time he entered into active duty, had only three complaints remotely related to his left leg/hip over a 22-year military career, and sought no further treatment until several years after service separation. Accordingly, the Board concludes that service connection is not established for a chronic left hip disability, including DJD and left hip replacement. ORDER Service connection for DJD of the left hip, to include left hip replacement, is denied. ____________________________________________ Gary L.
