Abstract
We had experienced three cases of limb-salvage operation on the knee joint. The first case was a 9-year-old female. She had a osteosarcoma of her right femur. Following 5 times of CDDP 100mg/m2, she underwent local wide excision and replacement of her femoral distal region with the ceramic implant. 31 months postoperatively she was free from disease, but her right leg was shortened by 5cm, and medio-lateral instability was moderate. The evaluation by Enneking (1982) was poor. The second case was a 12-year-old female. She had an aneurysmal bone cyst of her right femur. She underwent curettage of the femoral lesion. The lesion was again curetted and filled with the bone-cement. But the recurrence was shown on the X-ray. She was treated by excision and replacement of her knee joint with the ceramic implants. 23 months after the last operation, she had a good function of her right knee joint. The evaluation by Enneking was fair. The third case was a 74-year-old male. He had a osteosarcoma of his right tibia. Following two times of ADR 50mg/body (ia), He underwent the local wide excision, replacement of his right tibial proximal region and reconstraction of the medial and lateral collateral ligaments and patellar ligament. 17 months postoperatively, evaluation by Enneking was fair. However, he died of disseminated intravascular coagulation after the operation for a metastasis of the 7th thoracic vertebral body.
