Objective To evaluate the shortterm efficacy of osteoarticular allografts in the limb salvage of the proximal tibia. Methods From 1998 to 2003, 15 patients (7 males, 8 females; aged 14-56 yr, average 33) with bone tumor of the proximal tibia underwent osteoarticular allografts, among whom 7 had progressive giant cell tumor without any previous chemotherapy; 8 had malignant tumor with previous chemotherapy, including 6 patients with osteosarocoma, 1 with spindle cell sarcoma, and 1 with malignant fibrous histiocytoma. According to the Enneking system, the patients were classified into ⅠB (7 patients), ⅡA (2 patients), and ⅡB (6 patients). All the patientsunderwent the marginal resection with an allograft (average length 12 cm, range6-16 cm) implanted. Results The follow-up for an average of 21 months (range,3-58 months) revealed that among the 8 patients with malignant tumor of the proximal tibia undergoing chemotherapy, 5 had union of the bone, 3 had no union of the bone; among the 3 patients, 2 had a complication of infection and 1 had a local recurrence. All the 3 patients underwent amputation at the lower part of the femur. According to the Mankin score, 2 patients had a perfect result, 2 good, 1 fair, and 3 poor, with a 50% effectiveness rate. Among the 7 patients with progressive giant cell tumor at the upper part of the tibia, none had infection or local recurrence, but 2 hadnonunion of the bone and 2 had joint instability, aided by the kneeaidingsystem. According to the Mankin score, 3 patients had a perfect result, 2 good,and 2 fair, with a 71% effectiveness rate. Conclusion The osteoarticular allograft of the proximal tibia has many advantages in spite of a relatively highrate of complications, and it is the limb salvage of choicefor the progressivebenign or malignant bone tumors of the proximal tibia.
