HHS Harris Hip Score, MSTS Musculoskeletal Tumor Society, NED alive with no evidence of disease, NED rl no evidence of disease after treatment of a recurrence, NED m alive after treatment of metastases, DFD died from their disease, Patient 1 underwent the amputation for the local recurrence 26 months after surgery; The lung metastasis was found 20 months after surgery in Patient 6; In both HHS and MSTS scores, a highly statistically significance (P < 0.001) was observed between preoperative and postoperative assessments
