Abstract: 【Abstract】〓Objective〓To investigate the method and the clinical effect of arthroscopic therapy on localized pigmented villondular synovitis of knee. Methods〓The clinical material and therapy were reviewed retrospectively in 10 cases with localized pigmented villondular synovitis of knee confirmed by the MRI images, biopsy, surgery and pathology from September 2008 to May 2014. Follow-up of 9 months to 68 months, the functional recovery such as the postoperative knee pain, swelling and range of motion were evaluated according to the Lysholm knee functional score. Results〓All of 10 patients have no complications occurred in the postoperative follow-up period, and 2 patients relapse. The Lysholm knee functional score was 91.80±5.28 points, and obviously higher than which before surgery(47.50±16.28, P<0.01). Conclusion〓Arthroscopic therapy is an effective treatment with less invasion, fast recovery, and better function on localized pigmented villondular synovitis.

摘要： 【摘要】 目的 探讨关节镜下治疗局限型膝关节色素沉着绒毛结节性滑膜炎(PVNS)的方法及疗效。方法 回顾性分析2008年9月~2014年5月在我院术前行MRI检查、术后经病理证实的10例色素着绒毛结节性滑膜炎患者的临床资料及治疗方法,并对患者进行跟踪随访9~68个月,采用Lysholm膝关节功能评分了解患者术后患膝疼痛、肿胀及活动度等功能恢复情况。结果 10例患者在术后随访期均无并发症发生,复发2例,Lysholm 膝关节功能评分为91.80±5.28分,明显高于术前(P<0.01)。结论〓关节镜下对局限型色素沉着绒毛结节性滑膜炎的患者实施滑膜切除术,手术创伤小,术后膝关节功能恢复好,是一种安全有效的治疗膝关节局限型色素沉着绒毛结节性滑膜炎的方法。
