关节镜下自体腘绳肌腱及横穿钉固定治疗前交叉韧带断裂

目的探讨关节镜下应用自体腘绳肌腱及横穿钉固定重建前交叉韧带（ACL）的临床疗效。方法对21例ACL断裂患者,采用自体4股腘绳肌腱、2枚可吸收股骨横穿钉（Rigidfix）联合可吸收界面螺钉关节镜下重建ACL。对患者进行Lysholm评分。结果 20例获得随访,时间12~36（15±2.3）个月。Lysholm评分：术前为43~65（51.2±1.75）分,术后提高到75~98（89.7±1.7）分。优13例,良5例,一般2例。结论关节镜下应用自体腘绳肌腱及横穿钉固定重建ACL具有疗效确切、创伤小、患者康复快等优点。

Using autologous hamstring tendons and rigidfix for anterior cruciate ligament rupture by arthroscopy

Objective To analyze the features and clinical effect of use autologous hamstring tendons and rigidfix to reconstruct the disrupted anterior cruciate ligament by arthroscopy.Methods 21 patients with anterior cruciate ligament ruptures were repaired by using four-strand autologous hamstring tendons,double adsorbable Rigidfix absorbable interferences screws by arthroscopy.Lysholm score was used for the patients.Results 20 cases were followed up for 12~36（15±2.3） months.According to Lysholm score,13 cases were excellent,5 good,and 2 fair.The Lysholm score improved from 43~65（51.2±1.75） points to after operation 75 ~ 98（89.7±1.7） points.Conclusions Surgical repair of anterior cruciate ligament by arthroscopy by using autologous hamstring tendons and rigidfix has the features of effectiveness,minimally invasion,and quick recovery.
