Abstract: The upper-middle tibia is the multiple growth section of benign and malignant neoplasm, which is easy to result in bone defect after tumorectomy and it is a serious problem in orthopaedics. We reported a case about a huge benign or potential malignant tumor( giant cell tumor of bone) in upper-middle tibia and contrasted the advantage between the jade prosthesis and the allograft. Initially, the tumor had been curetted and then the upper-middle tibia had been given iliac bone graft, but the tumor recurred one year later. Then orthopedists gave the tumor excision and jade prosthesis replacement by the fixation of intramedullary screw. However, twenty one years later, the intramedullary screw fatigue fractured, orthopedists advised the patient be unloaded the jade prosthesis and be given the operative knee prosthesis surface replacement before allogeneic tibial condyle replacement. While 6 months later, the allogeneic bone in vivo had immunologic rejection and the knee was swelling, pain and no function. Finally, orthopedists gave the knee arthrodesis. Hence, we discovered that jade prosthesis had more advantages than allograft in proximal tibia of neoplastic bone defect and jade prosthesis was secure, durable, long period length, low immunological rejection and should be popularized in clinic.
