PRESERVATION OF THE KNEE JOINT IN PROXIMAL TIBIAL & DISTAL FEMUR BONE TUMORS



Abstract

Many patients with proximal tibial, distal femur aggressive benign or malignant bone tumors had been treated with wide resection and reconstruction of the knee joint with a tumor prosthesis or an allograft. Reconstruction of the extensor apparatus, infection, non-union, fracture, high cost and mechanical failure is still a problem. If the patient’s own knee can be preserved while allowing a safe tumor excision, better functional results can be obtained for a long time.

We describe a series of 9 patients with juxta-articular giant cell tumor around the knee treated by extended intra-lesional curettage and chemical cauterization . Articular surface was preserved and subchondral bone was reconstructed with autogenous bone graft. Full function of the limb was preserved in all except one patient with a mean follow up of 3 years.
