Surgical Treatment Of Campanacci Grade Ⅲ Giant Cell Tumor Of Bone Around Knee Joint

Objective:To compare the differences of postoperative functional evaluation,local recurrence and postoperative complications between curettage and inactivation with internal fixation and bone tumor resection with reconstruction in the treatment of giant cell tumor of bone(GCTB)around the knee joint.Method : Retrospectively analyzed the clinical data of 42 patients with Campanacci Grade III GCTB around the knee joint treated in our hospital from June 2011 to may 2020.And compared the operation time,postoperative hospital stay,postoperative assisted walking time,MSTS scores,the AKS scores and tumor recurrence.Then analyze the effect of the two different surgical methods on tumor outcome and recovery of lower limb functions.Result:All patients were followed up for an average of 46.7(7-110)months.The postoperative hospitalization days and postoperative walking time of the curettage and inactivation internal fixation group were lower than those of the tumor resection and reconstruction group,and had statistical significance(P < 0.05);The MSTS score and AKS function score of the curettage inactivated internal fixation group were higher than those of the tumor segment resection and reconstruction group,the difference was statistically significant(P < 0.05);the tumor recurrence rate in the tumor resection and reconstruction group was significantly lower than that in the curettage and internal fixation group,and had statistical significance(P < 0.05).Conclusion:Curettage and inactivation with internal fixation and bone tumor resection with reconstruction are effective methods for the treatment of Campanacci grade III GCTB around the knee joint.The former can preserve the knee joint function,postoperative hospital stay and early ambulation;the latter can significantly reduce the postoperative recurrence rate.
