关节镜下自体移植半腱肌和股薄肌重建前交叉韧带

目的:介绍关节镜下半腱肌股薄肌重建前交叉韧带(ACL)的手术方法和效果。方法:2007年9月～2011年5月我科共诊治34例ACL损伤患者,取自体半腱肌与股薄肌腱,在关节镜下使用带鞘可吸收挤压钉(Itrafix系统)固定胫骨端,使用2枚横向钉固定股骨端,重建ACL。观察固定后的稳定性和术后疗效。随访后用Lysholm评分标准评价手术前后关节功能。结果:本组34例,随访6～44个月。关节功能良好,Lysholm评分,术前53.08±4.2,术后92.05±3.7,术后评分明显提高,差异有统计学意义(P<0.01)。结论:关节镜下重建前交叉韧带,疗效好,操作简单,并发症少,宜临床推广。

Outcomes of arthroscopic reconstruction of anterior cruciate ligament with autografts from tendons of the semitendinosus-gracilis muscles

Objective:To assess the clinical effects of reconstructing anterior cruciate ligament(ACL) with the tendon autografts from the semitendinosus-gracilis muscles under arthroscope.Methods: Between Sept.2007 and May 2011,34 patients with ACL injury underwent treatment in our department by ligament reconstruction with autogenous semitendinosus-gracilis muscles.Arthroscopic fixation was performed in tibia epiphysis with sheathed absorbable crushing screw and in femur epiphysis with two transverse screws.All patients were observed for postoperative stability of the knees and treatment effects and followed up for functional recovery of the joint with Lysholm Knee Scoring Scale.Results: Follow-up ranging from 6 to 44 months showed that the total 34 patients obtained better recovery of joint function.Lysholm score before and after the surgery was 53.08±4.2 vs.92.05±3.7,which was statistically different(P<0.01).Conclusion: Arthroscopic reconstruction of ACL with autogenous semitendinosus-gracilis muscles can lead to better curative effect,with easy performance and fewer complications and thus,is worthy of wider clinical application.
