We performed a 2-staged arthroscopic-assisted surgical procedure to treat a patient with a large osteochondral lesion of the knee joint. The osteochondral lesion was too comminuted to reattach; in addition, the underlying bony defect was too deep. In the first stage, autogenous cortical bone was used for grafting the bony defect along with screw fixation. The second stage consisted of screw removal and transplantation of autogenous osteochondral graft overlying the chondral defect. The osteochondral grafts were taken from the non-weight bearing areas of the same knee.
