Chondral defects of the knee.
The surgical treatment of a young adult with a localized defect in the articular cartilage of the knee most commonly employs arthroscopic shaving and/or subchondral drilling.  Fresh osteochondral allografting is an alternative that is being performed with increasing frequency.  As of June 1993, fresh osteochondral allografts have been used in 90 knees in our institution. Thirty-eight of these knees have been evaluated two or more years postoperatively, and a successful result was obtained in 76%.  If the lesion was confined to the medial condyle, the success rate was 86%, but when both reciprocal surfaces were replaced (bipolar) the success rate was 56%.
