Follow-up

Patients were followed-up at 3-month intervals within 3 years of surgery, and at 6- or 12-month intervals 3 years later, for local control, metastatic spread, function of the limb, graft union and side effects. Meanwhile, the patients keep in touch with us via email or telephone. Functional outcome was evaluated by the Musculoskeletal Tumor Society (MSTS) system at the final follow-up, which is based on six parameters, including walking ability, pain, emotional acceptance, functional activities, the use of external support and gait (8). All patients with Ewing sarcomas and osteosarcomas received postoperative chemotherapy.
