Domino osteochondral autograft transplantation for osteonecrosis of the knee and femoral head: A case based review.

A domino osteochondral autograft transplantation enables the treatment of larger lesions compared to typical osteochondral autograft transplantation. Herein, we describe a case of steroid-induced knee osteonecrosis combined with osteonecrosis of the femoral head in which the knee was treated with domino osteochondral autograft transplantation. 4 Conclusion We reported a case in which we performed a domino osteochondral autograft transplantation using the resected femoral head as the donor for steroid-induced osteonecrosis of the knee that developed simultaneously with osteonecrosis of the hip. Since the necrotic lesion plus bone defect was larger in her left knee than in her right knee, we planned to operate on her left knee and right hip simultaneously so that we could use the resected femoral head as a donor site for the left knee surgery.
