Megaprosthetic replacement of knee in a young boy of 14 years

Now a days, Total Knee Replacement (TKR) is a common for elderly patients but is an uncommon procedure in young individuals. Recently, limb conservation surgery for malignant bone tumours like osteosarcoma around the knee has become a common indication for TKR in young. We report, here a histologically confirmed osteosarcoma in right proximal tibia of a 14-year-old boy who was managed successfully by limb salvage surgery using Global Modular Replacement System (GMRS, Stryker).
