The purpose of this study was to assess the outcomes of posterior cruciate ligament (PCL) reconstruction using the Ligament Augmentation and Reconstruction System (LARS) (JK Orthomedic Ltd, Dollard-des-Ormeaux, Quebec, Canada) artificial ligament. Compared with older artificial ligaments, the LARS, which has been used in Europe for 15 years, is more resistant to wear and tear, has satisfactory torsional fatigue resistance, and has good biocompatibility. The current is study included 38 double-bundle PCL reconstructions using the LARS artificial ligament in 38 patients. Mean patient age was 32.6 years, and mean time from injury to surgery was 6 months. Mean follow-up was 37 months (range, 30-68 months). The study endpoint was 2-year follow-up. Mean Tegner score improved from 3.4 ± 0.6 preoperatively to 6.0 ± 1.4 postoperatively (P<.001), and mean Lysholm score improved from 70.0 ± 11.0 pre-operatively to 91.7 ± 5.5 postoperatively (P<.001). Knee laxity decreased significantly postoperatively (P<.001), and no differences existed at 1- and 2-year follow-up. After surgery using the Y-type LARS artificial ligament, knee function and stability improved. Using the LARS artificial ligament for double-bundle reconstruction of the PCL avoids donor-site morbidity and disease transmission. The complication rate is low, and the results appear to be stable with time and comparable with those obtained with other grafts. Double-bundle PCL reconstruction with the LARS artificial ligament may be an alternative treatment option.
本研究的目的是评估使用韧带增强重建系统（LARS，JK Orthomedic有限公司，加拿大魁北克多拉尔德-德索莫，Dollard-des-Ormeaux）人工韧带进行后交叉韧带（PCL）重建的效果。与旧的人工韧带相比，已在欧洲使用15年的LARS人工韧带更耐磨损，具有令人满意的抗扭转疲劳性能，并且具有良好的生物相容性。本研究纳入了38例使用LARS人工韧带进行双束PCL重建的患者。患者平均年龄为32.6岁，受伤至手术的平均时间为6个月。平均随访时间为37个月（范围为30 - 68个月）。研究终点为2年随访。Tegner评分平均从术前的3.4±0.6提高到术后的6.0±1.4（P<0.001），Lysholm评分平均从术前的70.0±11.0提高到术后的91.7±5.5（P<0.001）。术后膝关节松弛度显著降低（P<0.001），在1年和2年随访时无差异。使用Y型LARS人工韧带手术后，膝关节功能和稳定性得到改善。使用LARS人工韧带进行PCL双束重建可避免供区并发症和疾病传播。并发症发生率低，结果似乎随时间稳定，且与其他移植物获得的结果相当。使用LARS人工韧带进行双束PCL重建可能是一种替代治疗选择。
