We experienced 2 patients with osteochondral defects of the medial femoral condyle who underwent autogenous osteochondral graft. In the first case, surgery was performed for osteonecrosis with two large osteochondral pegs transfer. The second case was treated using the mosaicplasty technique for osteochondritis dissecans. Grafts were taken from the non-weightbearing edges of the femoral condyles at the level of the patellofemoral joint. The secondary examination after surgery revealed that the lesions treated by autogenous grafts were covered with cartilage-like tissue. The duration of follow-up was 4 years in the first case and 1.5 in the second respectively. No clinical symptoms were seen. These results suggest that autogenous osteochondral bone graft seems to be a useful method in the treatment of osteochondral bone defect of the knee, although additional follow-up is required.
