关节镜下RapidLoc与FasTFix缝合器修复内侧半月板后角损伤40例

背景：目前关节镜下修复治疗内侧半月板后角损伤应用较多的主要有RapidLoc与FasTFix半月板缝合系统。 目的：比较RapidLoc与FasTFix半月板缝合器修复内侧半月板后角损伤效果。 设计、时间及地点：对比观察，于2007-01/2008-04在南方医科大学附属深圳医院运动医学科完成。 对象：选择内侧半月板后角损伤患者40例，年龄19~36岁，男29例，女21例，随机分2组，每组20例。 方法：在膝关节镜下分别采用RapidLoc与FastFix半月板缝合器修复损伤的内侧半月板后角，修复后采用个体化康复计划。 主要观察指标：① RapidLoc组与FastFix组修复效果，判断标准包括：关节疼痛交锁、肿胀、关节间隙压痛、McMurray试验。②两组临床愈合率。③并发症。 结果：各组病例全部得到随访，平均随访最短6个月，最长14个月。根据临床标准3例失败（RapidLoc2例，FastFix1例）。临床愈合率RapidLoc为90%；FasTFix为95%；两组差异无显著性意义（P < 0.05）。两组病例均未出现修复中血管、神经、肌腱损伤，修复后FastFix组1例感染。 结论：RapidLoc与FasTFix系统虽然固定方式与初始张力不同，但只要修复过程中仔细、修复后康复个性化，半月板修复后均可获得较高的临床愈合率。

RapidLoc and FastFix arthroscopic repair systems for posterior horn injury of the medial meniscus

BACKGROUND: Arthroscopic repair of posterior horn injury of the medial meniscus is performed by RapidLoc system and FasTFix system. OBJECTIVE: To evaluate clinical effect of arthroscopic repair of posterior horn injury of the medial meniscus by RapidLoc system and FasTFix system. DESIGN, TIME AND SETTING: Comparative observation was performed at Department of Sports Medicine, Shenzhen Hospital, Southern Medical University between January 2007 and April 2008. PARTICIPANTS: Forty patients with posterior horn injury of the medial meniscus, aged 19-36 years, 29 males and 21 females, were randomly divided into two groups (n=20). METHODS: All patients were respectively treated with RapidLoc system and FasTFix system. The rehabilitation plans were scheduled postoperatively and personally. MAIN OUTCOME MEASURES: Criteria for clinical healing included absence of locking, swelling, or joint line tenderness, and a negative McMurray test; The clinical healing rates between two groups was compared. The complications were evaluated. RESULTS: All patients were followed up for 6 to 14 months. According to the criteria for clinical healing, three cases failed including 2 undergoing RapidLoc system and 1 undergoing FasTFix system. The healing rate by RapidLoc system was 90% and by FasTFix system 95% respectively (P < 0.05). Vessel, nerve and tendon injuries took place in two groups, and one developed infection following FasTFix system treatment. CONCLUSION: Although fixation type and initial tension are different, appropriate application and postoperative rehabilitation procedure will achieve a good healing rate by both systems.
