Extra-articular wide tumor resection and limb reconstruction in malignant bone tumors invading the knee joint.
We demonstrate our procedure of extra-articular wide tumor resection and its clinical outcome. The knee joint including the femorotibial, patellofemoral and the proximal tibiofibular joints was totally resected without any view of articular cartilage and synovium. The resected limb was reconstructed with endoprosthesis of the knee joint. The average score of the limb function evaluated by ISOLS criteria was 69.3% in all patients. The limb function of these patients was almost the same as that of the patients who received the intra-articular procedure. The procedure of extra-articular resection was theoretically necessary and clinically practical.
