Clinical Outcomes of Patellofemoral Osteochondral Allograft Transplantation: A Prospective Analysis

Objectives: The use of osteochondral allograft transplantation (OAG) for chondral defects of the knee is increasing, particularly for defects involving the femoral condyles. The purpose of this study was to prospectively evaluate the clinical outcomes for patients undergoing patellofemoral OAG for symptomatic chondral lesions. Methods: Consecutive patients undergoing OAG for full-thickness patella and trochlear lesions between 2007 and 2014 by two senior surgeons were analyzed. Pre- and post-operative patient reported outcomes scores were collected, with a minimum 21-month follow-up. Patient demographics, preoperative clinical data including information on prior ipsilateral knee surgeries, and intraoperative details were analyzed for all patients. Complications, reoperations, and conversion to total knee or patellofemoral arthroplasty were recorded. Statistical analysis was conducted with student’s T-tests, with P
