Extensor Mechanism Allograft in Osteosarcoma of the Patella: A Case Report.

Abstract

CASE\nA 24-year-old female diagnosed with fibroblastic osteosarcoma of the patella underwent a total patellectomy and surgical reconstruction with a large bone-tendon allograft of the extensor mechanism and adjuvant chemotherapy. At 5 years postoperative, the patient has adequate disease control and excellent joint function.\n\n\nCONCLUSIONS\nReconstruction with an extensor mechanism allograft is an appropriate alternative for patients with malignant patella tumors without tumor contamination of the joint, allowing for satisfactory knee function and disease control.
