Citation Nr: 21071581 Decision Date: 11/30/21 Archive Date: 11/30/21 DOCKET NO. 17-44 326 DATE: November 30, 2021 REMANDED Entitlement to service connection for a left knee disorder is remanded. REASONS FOR REMAND The Veteran had certified active service from January 1997 to January 2001. He had additional duty with the Air Force Reserve. Entitlement to service connection for a left knee disorder. In its March 2019 Remand instructions, the Board of Veterans' Appeals (Board) directed that the Agency of Original Jurisdiction was to "ensure that all service treatment records and service hospital records from all periods of verified active duty service have been associated with the claims file". Additional personnel records pertaining to the Veteran's active service with the Marine Corps were subsequently incorporated into the record. The service treatment documentation previously of record indicates that the Veteran joined the Air Force Reserve in June 2004. The Veteran's complete periods of active duty, active duty for training, and inactive duty for training with the Air Force Reserve have not been verified and the service treatment records associated with that duty have not been requested for incorporation into the record. The Department of Veterans Affairs (VA) should obtain all relevant VA and private treatment records which could potentially be helpful in resolving the Veteran's claim. Murphy v. Derwinski, 1 Vet. App. 78 (1990); Bell v. Derwinski, 2 Vet. App. 611 (1992). The matters are REMANDED for the following action: Contact the National Personnel Records Center (NPRC) or the appropriate service entity and request verification of the Veteran's complete periods of active duty, active duty for training, and inactive duty for training with the Air Force Reserve and forward all available service treatment and personnel records associated with such duty for incorporation into the record.
