目的   探讨关节镜下手术联合体外放疗治疗膝关节色素沉着绒毛结节性滑膜炎(PWNS)的疗效。   方法   2005年1月至2010年1月收治26例膝关节色素沉着绒毛结节性滑膜炎患者关节镜下手术切除后6~8周,依据术中病灶范围及切除情况射野行体外放疗,采用直线加速器6MV-X射线,每次照射组织量200cGY,每周5次,总量为组织量2600-3000cGY。通过改良后的Ogilvie-Harris评分来评价手术疗效。   结果   随访20个月~36个月,所有患者局部病变无复发,术后终末随防Harris评分较术前明显提高(P<0.05)。   结论   PVNS是一组复发率较高的具有侵袭性行为的良性滑膜病变,给予积极关节镜下手术切除,术后联合辅助体外放射治疗可以减少和预防术后局部复发。
