半腱肌 股薄肌腱横杆悬挂固定法重建膝关节前交叉韧带

ACL Reconstruction with Semitendinosus and Gracilis Tendon Using Cross-pin Fixation

目的 介绍关节镜下横杆悬挂固定法（Althrex TransFixⅡ法）固定移植的半腱肌腱、股薄肌腱重建膝关节前交叉韧带的方法。方法 2003-01～2005-12，采用半腱肌、股薄肌腱横杆悬挂固定法重建膝关节前交叉韧带43例。其中，男性32例，女性11例。年龄19～67岁，平均年龄26．8岁。平均病程8．9个月。移植物股骨端行横杆悬挂法固定，胫骨端齿压钉固定。结果 43例患者中，40例获得随访，随访时间6～18个月，平均12．3个月。随访病例术前Lysholm评分为（49．8±2．7）分，随访时Lysholm评分（91．7±1．8）分．两者相比有显著性差异（P〈0．05）。结论 关节镜下半腱肌、股薄肌腱横杆悬挂固定法重建膝关节前交叉韧带，是一种微创、疗效确切的方法。

Objective To introduce the method of ACL reconstruction with semitendinosus and gracilis using Arthrex Trans Fix Ⅱ fixation. Methods From January of 2003 to December of 2005, semitendinosus and gracilis tendon and technique of Trans Fix fixation was used for reconstructing ACL in 43 cases. Of 43 cases; there were 32 male and 11 female,aged from 19 to 67 years（average 26.8 years old）;Average course of disease was 8.9 months. Trans Fix was used for the femoral tunnel fixation and dentation extrusion screw was applied for the tibial tunnel fixation. Results 40 cases were followed up, the follow - up duration ranged from 6 to 18 months（average 12.3 months）. Lysholm score was 49.8 ±2.7 and 91.7 ± 1.8, respectively before operation and at the time of follow- up. Pairedt- test showed that Lysholm score was significantly different with pre - operation（ P 〈 0.05）. Conclusion Using hamstring and TransFix for ACL recon- struction under arthroscopy is a mini - invasive technique and its curative effect is assured.
