关节镜下四股腘绳肌腱悬吊固定重建前交叉韧带的中期疗效观察

Middle-term outcomes of arthroscopic anterior cruciate ligament reconstruction with four-stand hamstring tendon autograft by suspending fixation

背景:以腘绳肌腱重建前交叉韧带股骨侧的固定方法有多种,如内置纽扣、界面螺钉等,每种重建方式都有各自的优点和缺点。目的:回顾性总结关节镜下微孔纽扣钢板悬吊固定4股自体腘绳肌肌腱移植重建前交叉韧带的中期临床效果。方法:对2005-05/2007-06内蒙古医学院第二附属医院运动医学外科收治的,关节镜下采用微孔纽扣钢板悬吊固定4股自体腘绳肌肌腱移植重建前交叉韧带的42例患者进行术后至少2.5年的随访。采用Lyshlom功能评分、IKDC2000评分来评价其临床效果。结果与结论:42例患者术后获得3.1(2.5～4)年随访。术前Lysholm膝关节评分法评分为(44.34±7.12)分,末次随访时为(86.60±6.48)分;术前IKDC2000评分为(48.46±17.53)分,末次随访时IKDC2000评分为(92.42±5.87)分。手术前后两种评分比较差异均有显著性意义(P<0.01)。说明关节镜下以微孔纽扣钢板悬吊固定4股自体腘绳肌腱移植重建前交叉韧带,可以取得比较满意的中期临床疗效。

BACKGROUND：There are a variety of methods for internal fixation of femur based on hamstring tendon anterior cruciate ligament （ACL） reconstruction,such as internal button and interface screw. Each reconstruction has advantages and disadvantages. OBJECTIVE：To retrospectively evaluate the medium clinical results of arthroscopic ACL reconstruction with four-strand hamstring tendon autograft by suspension fixation. METHODS：The 42 cases undergoing arthroscopic ACL reconstruction with four-strand hamstring tendon autograft by suspension fixation in Department of Arthroscope and Sports Medicine,Second Affiliated Hospital of Inner Mongolia Medical College from May 2005 to June 2007 were followed up for at least 2.5 years. Evaluations were performed using Lyshlom score scale and IKDC2000 score scale. RESULTS AND CONCLUSION：The patients were followed up for 3.1 （2.5-4） years. Preoperative Lyshlom score was （44.34±7.12） scores,and （86.60±6.48） scores at the final follow up; preoperative IKDC2000 score was （48.46＋17.53） scores,and （92.42±5.87） scores at the final follow up. All score scales were significantly improved than preoperative scores （P 0.01）. Results showed that arthroscopic ACL reconstruction with four-strand hamstring tendon autograft by suspension fixation can obtain favorable middle clinical results.
