Midterm Outcomes of Patellofemoral Osteochondral Allograft Transplantation: A Comparison of Patellar, Trochlear, and Bipolar Grafts

Patients undergoing patellofemoral OCA transplantation exhibited high survival rates at 5 and 10 years, along with improved patient-reported outcomes when performed without concomitant tibial tubercle osteotomy. Trochlear grafts had greater survivorship than isolated patellar or bipolar grafts, and outcomes were comparable to those of OCA transplantation performed in the femoral condyles.
