Abstract

Case: Autologous chondrocyte implantation (ACI) is an established technique for the treatment of osteochondral lesions of the knee. For larger lesions with a substantialamount of bone loss, ACI using a bilayer collagenmembrane with bone-grafting has been demonstrated to offer good to excellent results in the tibiofemoral joint, but little has been reported on its use in the patellofemoral joint. We report on the 2-year follow-up of this technique of ACI with bone-grafting used for the treatment of a large osteochondral defect in the lateral aspect of the trochlea of the knee in an 18-year-old, active female patient. Conclusion: This case illustrates that ACI with bone-grafting using such a "sandwich" technique can be an effective treatment option for osteochondral lesions of the trochlea in the knee.
