关节镜下横杆悬挂法重建前交叉韧带

Arthroscopic anterior cruciate ligament reconstruction using the Transfix technique

背景:固定移植腱的方法多种多样,每种系统各有其优势,对于用何种方法固定移植的肌腱,目前国际上仍没有一个统一的标准。目的:观察关节镜下横杆悬挂固定法固定自体腘绳肌腱重建膝关节前交叉韧带的临床疗效。方法:选择2008-09/2010-01于安徽医科大学第一附属医院骨二科行膝关节前交叉韧带重建的患者20例。所有患者均应用股骨端横杆悬挂固定和胫骨端界面螺钉组成前交叉韧带固定系统行自体腘绳肌腱前交叉韧带单束重建。重建后随访6～16个月(平均10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,无严重并发症发生,重建后膝关节活动度均正常。所有患者术前Lysholm膝关节评分为(60.20±11.54)分,重建后6个月为(92.95±3.55)分,较术前明显提高(P<0.05)。截至重建后6个月,IKDC评分18例正常,其余2例接近正常。说明关节镜下应用自体腘绳肌腱横杆悬挂固定法重建前交叉韧带是一种疗效确切的固定方法。

BACKGROUND：The fixed tendon graft have many ways,each system has its own advantages as well as shortcomings.For fixed by what method the tendon graft,the current is still not a unified international standard.OBJECTIVE：To retrospectively evaluate clinical results of arthroscopic anterior cruciate ligament（ACL） reconstruction with hamstring autograft and the Transfix technique.METHODS：A total of 20 patients that had been treated with arthroscopic single bundle ACL reconstruction by use of hamstring tendon autografts with ACL fixation system composed of femoral fixation via Transfix and tibia fixation via interference screw in Second Department of Orthopedics,First Affiliated Hospital of Anhui Medical University from September 2008 to January 2010.Twenty cases were followed up for 6-16 months（average 10 months） to assess the patient＇s range of motion,stability,and other indicators.RESULTS AND CONCLUSIONS：During follow-up,no patients had serious complications,and all patients gained normal knee activity.The mean Lysholm score was（60.20±11.54） preoperatively and（92.95±3.546） postoperatively（P〈0.05）.Six months after the operation,on the basis of the final International Knee Documentation Committee grade,18 knees were normal,2 were nearly normal.This study concludes that the reconstruction of ACL under arthroscopy with hamstring tendons and the Transfix technique is an effective method.
