Novel limb-sparing technique for proximal tibial osteosarcoma: Patella Chevron Osteotomy with pedicle cryotherapy and bone-on-polyethylene reconstruction: A case report

This case report presents a novel surgical approach for proximal tibial osteosarcoma in a pediatric patient. The technique-combining patella chevron osteotomy, pedicle cryotherapy, and bone-on-polyethylene reconstruction-demonstrated excellent oncologic control, functional preservation, and growth potential. It may offer improved long-term outcomes and reduce revision surgery rates, particularly in resource-limited settings.
