全关节置换术治疗色素沉着绒毛结节性滑膜炎的效果

目的探讨全关节置换术治疗色素沉着绒毛结节性滑膜炎的可行性及临床效果。方法1994年1月～2004年12月，对经病理检查证实的8例色素沉着绒毛结节性滑膜炎病人实施了全关节置换术（髋关节3例，膝关节5例），术前均行X线检查。6例弥漫型病例行滑膜全切术＋全关节置换术；2例局限型病例行滑膜部分切除术＋全关节置换术。术后均进行了系统的康复训练。结果术后随访1．5～12．0年，8例病人假体位置良好并获得了满意的关节活动度。所有病例均无复发。结论全关节置换术治疗反复复发导致关节骨软骨破坏或者并发骨性关节炎的色素沉着绒毛结节性滑膜炎病例，可获得良好的临床效果。

TREATMENT OF PIGMENTED VILLONODULAR SYNOVITIS WITH TOTAL JOINT REPLACEMENT

Objective To explore the feasibility of treating pigmented villonodular synovitis with total joint replacement. Methods Eight cases with pigmented villonodular synovitis confirmed by pathology were treated with total hip(3 cases) and total knee replacement(5 cases) during 1999 and 2004.Preoperative radiography was done for all the cases.Six patients with diffused lesion underwent total synovectomy and total joint replacement;two patients with localized disease underwent partial synovectomy and total joint replacement,and followed by systematic rehabilitation training. Results Postoperative follow-up for 1.5 to 12.0 years showed that all the prostheses were well fixed and functioning satisfactorily.No recurrence was reported. Conclusion Good clinical results could be achieved by total joint replacement in patients with pigmented villonodular synovitis complicated with bone and cartilage destruction in the joint or patients with recurrent arthritis.
