Comparison of tumor curettage and resection for treatment of giant cell tumor of the bone around the knee joint

OBJECTIVE: To analyze the efficacies of tumor curettage and resection for treatment of giant cell tumor of the bone (GCTB) around the knee joint (KJ). METHODS: A total of 126 KJ-GCTB cases were treated at our department from August 2011 to February 2015. These cases were divided into two groups (A and B) according to treatment methods. Group A underwent tumor curettage, while group B underwent tumor resection. RESULTS: The relapse rates did not differ significantly between the groups (P>0.05), while the complication rate in group A was significantly lower than that in group B (P<0.05). In addition, the Enneking score for group A was significantly higher than that for group B (P<0.05); in addition, postoperative local recurrence, histopathological grading according to Jaffe, and radiographic imaging-based Campanacci’s staging positively correlated (P<0.05). CONCLUSION: Tumor curettage was the preferred surgical approach for patients with KJ-GCTB.
