Limb Salvage Surgery
A 10-year-old boy presents with a 3-month history of progressive knee pain and swelling without trauma. MRI reveals a 12cm tumor centered in the distal femoral metaphysis with soft tissue extension. Biopsy confirms high-grade osteosarcoma. Staging shows no metastatic disease. The tumor involves the distal femoral epiphysis and approaches but does not invade the popliteal vessels. The treating team discusses limb salvage options with the family, including endoprosthetic replacement, allograft reconstruction, and rotationplasty.
