title: Reconstruction of skeletal deficits at the knee. A comprehensive osteochondral transplant program.
abstract: From 1971 to 1982, 110 osteochondral transplants with follow-up evaluation were performed for treatment of skeletal deficits caused by degenerative, traumatic, and neoplastic diseases largely involving the knee joint. Seventy-eight small-fragment fresh allografts were transplanted for repair of old tibial plateau osteochondral fractures, osteonecrosis, and unicompartmental osteoarthritis. Thirty-two large-fragment grafts were performed following en bloc excision of bone tumors. Of these, 22 were allografts, three were vascularized fibular autografts, and seven were a combination of allografts and vascularized fibular autografts. In this large-fragment group, three grafts have been removed for tumor recurrence, two for infection, and one for a stress fracture. The results of these transplants have proved particularly rewarding in the old plateau fractures, for traumatic loss of bone and cartilage (osteonecrosis), and after en bloc excision of giant cell tumors.
