关节镜下LARS韧带重建后交叉韧带的早期临床疗效分析

目的 回顾性分析关节镜下LARS韧带重建后交叉韧带的早期临床疗效。方法 自2016年8月~2017年10月筛选50例确诊为后交叉韧带损伤患者。其中应用LARS韧带重建后交叉韧带患者22例设为实验组，应用自体半腱肌、股薄肌重建后交叉韧带的患者28例设为对照组。记录患者术后并发症发生率，采用Lysholm、IKDC、Tegner膝关节运动评分标准对术后膝关节的稳定性与活动性随访评分。结果 所有患者均获得随访，随访时间3~6个月。对照组术后并发症的发生率高于实验组（21.43% vs 9.09%），实验组在避免膝关节僵硬及下肢深静脉血栓方面优于对照组（4.55% vs 17.86%），差异具有统计学意义（P＜0.05）；两组患者术前Lysholm评分、IKDC评分以及Tegner评分比较，差异无统计学意义（P＞0.05），在术后随访过程中，实验组Lysholm评分、IKDC评分以及Tegner评分优于对照组，差异有统计学意义（P＜0.05）。结论 关节镜下LARS韧带重建后交叉韧带创伤小，降低术后并发症，有效的恢复膝关节的稳定性和功能性，具有较好的近期临床疗效。

Analysis of the Early Clinical Effect of Arthroscopic Reconstruction of the Posterior Cruciate Ligament with LARS Ligament

Objective To retrospectively analyze the early clinical effects of arthroscopic reconstruction of the posterior cruciate ligament by LARS ligaments.Methods From August 2016 to October 2017, 50 cases of patients with posterior cruciate ligament injury were screened.Among them, 22 patients with post-cruciate ligament reconstruction with LARS ligament were set as the experimental group, and 28 patients with post-cruciate ligament reconstruction with autologous semitendinosus and gracilis muscle were set as the control group.The incidence of postoperative complications was recorded, and the stability and activity of postoperative knee joint were evaluated by Lysholm, IKDC and Tegner.Results All patients were followed up for 3-6 months.The incidence of postoperative complications in the control group was higher than that in the experimental group(21.43% vs 9.09%), The experimental group was superior to the control group in avoiding knee stiffness and deep venous thrombosis of lower limbs (4.55% vs 17.86%) and the difference was statistically significant (P<0.05).There was no statistically significant difference (P>0.05) between the two groups in terms of Lysholm score, IKDC score and Tegner score before surgery. During the postoperative follow-up, the Lysholm score,IKDC score and Tegner score of the experimental group were superior to the control group, and the difference was statistically significant(P<0.05).Conclusion The post-arthroscopic reconstruction of the cruciate ligament with LARS ligaments is less traumatic, can reduce the postoperative complications, effectively restore the stability and function of the knee joint, and has a good short-term clinical effect
