关节镜下人工韧带重建前交叉韧带临床研究

Clincal report on arthroscopic reconstruction of anterior cruciate ligament using ligament advanced reinforcement system

目的总结关节镜下先进韧带加强系统（LARS，ligament adv anced reinforcement system）人工韧带在膝关节前交叉韧带（ACL，anterior cruciate ligament）重建中的早期疗效及注意事项。方法2006年1月一2010年8月，对15例膝关节ACL损伤患者行关节镜下LARS人工韧带重建术。结果术后患者均随访9～24个月，平均15个月，术后膝关节不稳症状消失，屈伸活动度为0°-135°；术后14例前抽屉试验、Lanchman试验和轴移试验均为阴性，1例出现可疑Lanchman试验和前抽屉试验阳性；Lysholm膝关节均分为（86．40±2．14）分，与术前比较差异有显著性（P〈0．05）。结论LARS人工韧带重建ACL早期效果满意；术中应尽量保留较多的韧带残端和使用准确的等长重建方法。

Objective To explore the operative techniques and preliminary clinical effect of arthroscopic reconstruction of anterior cruciate ligament （ACL） using ligament advanced reinforcement system （LARS）. Methods From Jan. 2006 to Aug. 2010,15 patients with ACL rupture were treated with LARS under arthroscopic observation. All were males, aged 23.0-53.0 years old. All patients had un- stable feeling in their knees. The anterior drawer test, Lanchan test and pivot shift test were positive. The average Lyshlom scores was （43.30 ± 1.32） .Results All the patients were regular followed up for 9 to 36 months （15 months at average）. All the patients feel their knees with no more unstability. The pivot shift test showed 15 case（-）; the anterior drawer test and Lanchan test showed 14 case（-）, 1 case（± ）. Lysholm scores was （86.40 ± 2.14）（P 〈 0.05） with significant differences with that before operation. Conclusion ACL arthroscopic reconstruction with the use of LARS artificial ligaments leads to rapid recovery and satisfactory clinical efficacy.
