A patient with postoperative recurrence of bone giant cell tumor in right distal femur was treated with wide resection of tumor and replacement of alcohol-deactived autograft-prothesis composite (Case 2). (a) The preoperative X-ray image showed the osteolytic lesion encroaching articular surface and thinner cortical bone in medial condyle of right femur, (b) The preoperative CT image showed the lesion exceeding half of femoral diameter, (c-d) At 9-month after operation, the motion of right knee joint was 0°- 90°, (e) At 25-month after operation, the X-ray image showed bone healing and satisfactory space of prothesis without lossening and breakage, and the ISOLS graft score is 35.
