Osteochondral defects of the knee are a common finding at the time of arthroscopic intervention. Purpose/Hypothesis. To report our outcomes after utilizing a new technique of osteochondral allograft transplantation for focal cartilage defects. Study Design. Case series. Methods. All patients treated with osteochondral allograft transplantation with a Zimmer Chondrofix plug (Zimmer Inc., Warsaw, IN) for focal cartilage defects over a 12-month period were followed up at a minimum of 24 months. Failures were documented and radiographs were evaluated. Results. 61 knees (58 patients) underwent grafting. Three cases were lost to follow-up. In the remaining 58 cases the average age was 40 (range 18–59). At a mean follow-up of 28 months (range 24–36), there were 5 failures requiring further surgery. Mean KOOS scores in the Pain, Symptoms, ADL, Sports, and Quality of Life dimensions were 82, 79, 84, 66, and 58, respectively. Radiographs demonstrated maintenance of the subchondral bone without graft absorption or subsidence. Conclusions. Our observations suggest that osteochondral allograft transplantation leads to a satisfactory activity level and function at early follow-up while avoiding the inherent complexities associated with other cartilage restoration techniques. Longer follow-up is warranted to monitor the subchondral bone, articular surface, and patient outcome measures.
