Entitlement to service connection for a right knee disability is remanded.

Board reasoning

The Board found a remand was necessary to correct a duty-to-assist defect and to obtain outstanding private records, reasoning that the most recent medical opinion did not adequately consider in-service knee complaints and lay statements, creating a pre-decisional error that requires remand. The Board noted the need to obtain records and provide a new medical opinion addressing all diagnosed right knee disabilities and their relation to service.
