关节镜下腘绳肌单束重建前交叉韧带损伤的临床疗效

Clinical efficacy of single bundle reconstruction with hamstring tendons under arthroscopy on anterior cruciate ligament injury

目的:探讨关节镜下腘绳肌单束重建前交叉韧带(ACL)损伤的临床疗效。方法:回顾2013年6月至2016年6月因单纯ACL损伤行关节镜下重建患者27例,均采用关节镜下自体腘绳肌腱(半腱肌、股薄肌)单束重建,随访1年,观察术前、术后0.5年、1年膝关节活动度、Lachman试验、前抽屉试验及Lysholm评分。结果:术后1年、术后0.5年患者膝关节活动度和Lysholm评分均较术前提高(P<0.05),且术后1年优于术后0.5年(P<0.05);术后1年、术后0.5年患者Lachman试验和前抽屉试验阳性率均较术前降低(P<0.05),但术后1年与术后0.5年比较,差异无统计学意义(P>0.05)。结论:关节镜下腘绳肌单束重建治疗ACL损伤手术创伤小,术后恢复快,临床疗效好。

Objective:To explore the clinical efficacy of single bundle reconstruction with hamstring tendons under arthroscopy on anterior cruciate ligament(ACL)injury.Methods:From June 2013 to June 2016,27 patients with simple ACL injury were treated with single bundle reconstruction with their own hamstring tendons under arthroscopy(semitendinosus,gracilis)and were followed up for 1 year,with scores of knee joint activity,Lachman tests,anterior drawer tests and Lysholm before operation,half a year and 1 year after operation observed.Results:The scores of knee joint activity and Lysholm 1 year and half a year after operation were significantly higher than those before operation(P<0.05),and the scores of 1 year after operation were higher than those of half a year after operation(P<0.05).The positive rates of Lachman tests and anterior drawer tests 1 year and half a year after operation were significantly lower than those before operation(P<0.05),but there was no significant difference between 1 year and half a year after operation(P>0.05).Conclusion:Single bundle reconstruction with hamstring tendons under arthroscopy on ACL injury has less trauma and quick recovery after operation,which is clinically effective.
