目的 探讨关节外改良缝合法联合关节镜治疗半月板周围型囊肿的疗效。方法 2010年1月-2014年12月，对18例半月板周围型囊肿患者治疗采用关节内镜下部分切除或缝合破裂半月板，关节开放外手术切除囊壁，并采用改良缝合法修复。术前术后进行膝关节最大屈伸活动度（ROM）比较及Lysholm功能评分。结果 术后切口均I期愈合，无伤口感染、神经、血管损伤等早期并发症发生。术后18例均获随访，随访时间12～24个月，平均12.5个月。随访期间囊肿均无复发，患者术前症状消失或明显减轻，关节活动度恢复正常。术前膝关节ROM（113.7±17.6）°，术后增加至（139.1±9.6）°，术前Lysholm评分为（68.3±23.2）分，术后提高至（97.3±22.1）分。经t检验分析，差异有统计学意义（P <0.01）。结论 开放手术联合关节镜治疗半月板周围型囊肿操作简便、症状缓解明显及无复发，可获得确切的临床疗效。
【Objective】 To analyze the curative effect to meniscal peripheral cyst treated by the modified suture method combined with arthroscopic. 【Methods】 18 cases of meniscus peripheral cyst were treated by partial resection or suture meniscus rupture in the joint through arthroscopy. The cyst wall was removed outside of joint, and using modified suture to repairing margin. The function scores of preoperative and the ones of after operation were compared by the range of motion (ROM) of knee and Lysholm score. 【Results】 All the incision were primary healing after surgery, no early complications of wound infection, no injury of nerve or blood vessel. After operation, 18 cases were followed up, followed up for 12～24 months, average 12.5 months. The cysts were no recurrence during follow-up, patients with preoperative symptoms disappeared or reduced significantly, the activity of joint were returned to normal. The sum of ROM of knee was (113.7 ± 17.6)° preoperatively, being increased to (139.1 ± 9.6)° postoperatively. Preoperative Lysholm score was (68.3 ± 23.2), being increased to (97.3 ± 22.1) postoperatively. The differences were significant by the analysis of t test (P < 0.01). 【Conclusions】 The course of treatment of meniscal peripheral cyst by the modified suture method combined with arthroscopic is simple and convenient. Symptoms is alleviated obviously and no recurrence. All in all we can obtain the exact clinical efficacy through this method.
