Case in brief
Two patients with osteosarcoma around the knee underwent joint-sparing limb-salvage surgery using patient-specific 3D-printed anatomical models for intraoperative verification of osteotomy levels. A 16-year-old girl had proximal tibial osteosarcoma and received a wide resection with a frozen autograft. A 24-year-old man with proximal fibular osteosarcoma, initially considered for amputation, underwent successful joint-sparing resection after chemotherapy. Both achieved negative margins and no recurrence at follow-up.
Diagnostic / clinical pearl
Patient-specific 3D-printed models can enhance surgical planning and intraoperative verification in osteosarcoma surgeries, potentially improving outcomes in joint-sparing procedures.
