关节镜下LARS人工韧带重建膝关节后交叉韧带临床效果观察

The clinical observation of arthroscopic reconstruction of posterior cruciate ligament with LARS artificial ligament

目的观察关节镜下LARS人工韧带重建膝关节后交叉韧带的临床效果。方法选取北部战区总医院2016—2019年收治的因膝关节后交叉韧带损伤行关节镜下LARS人工韧带重建手术的25例患者(25膝)为研究对象。术后随访10~16个月,平均12个月。观察患者的切口愈合和并发症发生情况,比较术前和术后的Tegner评分和Lysholm评分。结果患者术后切口均Ⅰ期愈合,无手术相关并发症发生。患者术后Tegner评分为(6.1±1.2)分,高于术前的(3.5±0.6)分,差异有统计学意义(P<0.05)。患者术后Lysholm评分为(91.2±3.9)分,高于术前的(65.7±9.1)分,差异有统计学意义(P<0.05)。结论关节镜下LARS人工韧带重建膝关节后交叉韧带安全有效,无供区损伤,组织兼容性优,可快速恢复关节功能及稳定性。

Objective To assess the outcomes of posterior cruciate ligament(PCL)reconstruction using LARS artificial ligament.Methods A total of 25 patients with PCL reconstruction using LARS artificial ligament were enrolled in this study from 2016 to 2019.The postoperative follow-up was 10 to 16 months.The wound healing and complications were observed, preoperative and postoperative Tegner scores and Lysholm scores were compared.Results Postoperative incisions of all patients healed in Ⅰ stage, and no operation-related complications occurred.The postoperative Tegner score was(6.1±1.2)points, which was higher than(3.5±0.6)points before surgery, and the difference was statistically significant(P<0.05).After treatment, Lysholm score was(91.2±3.9)points, which was higher than that of preoperative(65.7±9.1)points, P<0.05.Conclusion PCL reconstruction using LARS artificial ligament is safe and effective, with no donor site injury, good tissue compatibility, and rapid restoration of joint function and stability.
