Two cases of giant cell tumor (GCT) in the distal femur are reported in this study. The first case was 44-year-old female complaining of right knee pain, en bloc resection was performed. The second case was 49-year-old male with pathological fracture caused in the traffic accident in the left distal femur. In this case, the tumor was extending to the articular cartilage, so en bloc resection of the tumor including articular cartilage of the medial edge was performed and curettage of residual tumor mass was added beneath the articular cartilage. In both cases, iliac cancellous bone grafting with A-W glassceramic granule was performed into the bony defect, and covered with an iliac bone block combined with reconstruction of the medial collateral ligament.
No complication nor severe functional loss of the knee joint were seen after the operation in both cases. On roentgenographic evaluiation, no local reccurrence have been detected for more than two years. GCT is known as a locally aggressive neoplasm, so careful attention for reccurrence should be paied after the operation.
