Partial Epiphyseal Preservation and Intercalary Allograft Reconstruction in High-Grade Metaphyseal Osteosarcoma of the Knee

Abstract

Preservation of the epiphysis in high-grade metaphyseal osteosarcoma at the knee is an alternative in carefully selected patients. Crucial factors needed to obtain local tumor control and achieve an acceptable functional result are a positive response to chemotherapy, accurate preoperative assessment of tumor extension to the epiphysis, and appropriate fixation techniques for intercalary allografts.
