Clinical Outcomes of Unipolar Versus Bipolar Patellofemoral Fresh Osteochondral Allograft Transplantation
Listen to this summary
The authors aimed to compare the clinical outcomes, including graft failure rates, reoperation rates, and patient-reported outcomes (PROs), between unipolar and bipolar patellofemoral osteochondral allograft (OCA) transplantation after a minimum follow-up of two years. Their findings indicated that while bipolar lesions were associated with a higher risk of graft failure, both unipolar and bipolar transplantations resulted in similar improvements in PROs and comparable reoperation rates, suggesting that both techniques are effective for patients in this cohort.
