关节镜下前交叉韧带袖套状保残重建的临床效果

目的:观察袖套状保留残端的关节镜下前交叉韧带重建的临床效果。方法:收集2012年1月至2014年12月于骨科就诊的42例前交叉韧带损伤患者,其中男17例,女25例,平均年龄28.4岁,平均受伤时间5.5周(2~12周)。采用关节镜下重建前交叉韧带,同时保留胫骨侧韧带残端,通过滑膜袖套恢复残端张力。治疗前及治疗后2、6、12个月采用Lachman试验、前抽屉试验对稳定性进行评价,术后12个月采用Lysholm评分和Tegner运动分级评价膝关节功能。治疗前和治疗后12个月行膝关节MRI检查。结果:术后2、6、12个月Lachman试验、前抽屉试验均为阴性。术前Lysholm评分37.8±7.1,Tegner评分2.1±0.4;术后12个月的Lysholm评分96.8±6.1,Tegner评分6.2±0.9,均高于术前。术后12个月复查MRI显示前交叉韧带显影良好。结论:关节镜下前交叉韧带袖套状保残重建可以获得良好的临床效果。

Clinical outcome of arthroscopic anterior cruciate ligament remnant-preserving reconstruction

Objective: To evaluate the clinical outcome of arthroscopic anterior cruciate ligament (ACL) reconstruction with remnant cuff preservation.Methods: There were 42 cases of ACL tear were performed reconstruction in our department from January 2012 to December 2014.The patients were 28.4 years old on average, 17 males and 25 females.ACL reconstruction was performed under arthroscopy with remnant cuff preservation.The stability of knee was assessed by Lachman test and anterior drawer test.The function of knee was assessed through Lysholm score and Tegner activity rating.MRI of the knee was checked 12 months postoperatively.Results: The stability tests of all patients were negative postoperatively.Lysholm score of all patients 12 months after operation was 96.8±6.1, which was significantly better than 37.8±7.1 of preoperatively.Tegner activity rating of all patients 12 months after operation was 6.2±0.9, which was significantly better than 2.1±0.4 of preoperatively.It showed the grafts were very well in MRI 12 months after operation.Conclusion: Arthroscopic anterior cruciate ligament remnant-preserving reconstruction could restore the stability of knee.
