自体腘绳肌双束与单束重建膝关节前交叉韧带

背景：前交叉韧带重建的方式是决定修复效果的关键因素。自体腘绳肌双束与单束重建膝关节前交叉韧带是临床上常用的修复方法。目的：比较自体腘绳肌双束与单束重建膝关节前交叉韧带的临床疗效。方法：回顾分析了2005-05/2009-06于中南大学湘雅二医院住院的56例急性前交叉韧带Ⅲ度损伤的患者,其中36例行单束自体腘绳肌重建术,20例行双束自体腘绳肌重建术,所有患者前交叉韧带的重建均由同一医师完成,术后随访16～42个月,评估患者的关节活动度、稳定性等指标。结果与结论：随访期间,所有患者的关节活动度均恢复正常,无伸膝受限。两种重建术后患者的Lysholm-Tegner和IKDC膝关节综合功能评定结果、KT-1000检测结果差异均无显著性意义（P〉0.05）,术后1年,取出界面螺钉时行关节镜检查,所有患者均未见明显的重建韧带松弛,说明双束与单束自体腘绳肌重建急性前交叉韧带损伤疗效相近。

Arthroscopic double-bundle versus single-bundle hamstring tendons for the reconstruction of the anterior cruciate ligament

BACKGROUND：Anterior cruciate ligament（ACL） reconstruction is the key factor to determine repairing effect.Arthroscopic double-bundle hamstring tendons and single-bundle reconstruction of the ACL is a common repairing method in clinic.OBJECTIVE：To compare the clinical outcomes of arthroscopic double-bundle hamstring tendons and single-bundle for the reconstruction of the ACL.METHODS：A total of 55 cases with acute grade Ⅲ ACL from The Second Xiangya Hospital of Central South University between May 2005 and June 2009 were retrospectively analyzed,including 36 cases treated with single-bundle hamstring tendons reconstruction,20 cases treated with double-bundle hamstring tendons and reconstruction.All patients received the same procedure performed by the same surgeon.All patients were followed up for 16-42 months,and the range of motion,stability,and other indicators were assessed.RESULTS AND CONCLUSION：During follow-up,the range of motion of all patients was recovered without extension of knee joint.There was no significant difference in Lysholm-Tegner,IKDC knee comprehensive functional evaluation results,and KT-1000 detection（P 0.05）.Patients underwent arthroscopy when removing the interference screw at one year after operation,and who had no significant reconstruction of ligament laxity.The clinical outcomes of ACL reconstruction with single-bundle and double-bundle hamstring tendons are similar.
