The Board granted service connection for right and left knee patellofemoral dysfunction, finding that the Veteran's current bilateral knee disability is etiologically related to his active service.

The Veteran's appeals for increased ratings were dismissed due to the Veteran withdrawing their appeal prior to a decision being made.

The Veteran's claim for TDIU due to a single disability was denied as the evidence did not show that he had a single service-connected disability that rendered him unable to work. The issue of an effective date prior to July 15, 2009, for TDIU is dismissed as moot.
