关节镜下单根LARS人工韧带重建后交叉韧带及内侧副韧带短期临床疗效观察

目的观察后交叉韧带(posterior cruciate ligament,PCL)、内侧副韧带(medial collateral ligament,MCL)同时损伤后,应用LARS人工韧带关节镜下重建PCL,并同时利用残余LARS人工韧带重建MCL的短期临床疗效。方法对8例关节损伤的患者在关节镜下行LARS人工韧带重建PCL,同时利用残余人工韧带重建MCL,术后随访6个月,比较术前、术后膝关节Lysholm评分和稳定性。结果 8例患者术前物理检查均表现为膝关节不稳,术后所有患膝不稳定表现消失。术后无膝关节感染、韧带自发断裂和韧带松动并发症,屈膝活动度110°～120°,术后1、3、6个月膝关节Lysholm评分均较术前增高,差异具有统计学意义(P<0.05)。结论应用LARS人工韧带关节镜下重建PCL,同时利用残余人工韧带修复MCL,术后膝关节可获得即时稳定,利于膝关节早期活动,减少相关并发症的发生,短期临床疗效满意。

Simultaneous reconstruction of posterior cruciate and medial collateral ligaments using LARS artificial ligament by arthroscopy

Objective The purpose of this study was to observe the clinical effects of simultaneous reconstruction of the posterior cruciate ligament(PCL) and medial collateral ligament(MCL) using LARS artificial ligament by arthroscopy in the treatment of combined injuries of both PCL and MCL.Methods We simultaneously reconstructed PCL and MCL with LARS artificial ligament under the arthroscope for 8 patients with combined injuries of both PCL and MCL in the knee.We followed up the patients for 6 months and compared the Lysholm scores and stability of the knee joints before and after the operation.Results Unstability of the knee joints was found in all the patients before surgery,but disappeared postoperatively.There were no postoperative complications such as knee joint infection,ligament rupture,and ligament loosening.The knee flexion was between 110° and 120°,and the Lysholm scores were significantly increased at 1,3 and 6 months as compared with those before surgery(P<0.05).Conclusion Simultaneous reconstruction of PCL and MCL using LARS artificial ligament can achieve immediate stability and early movement of the knee joints with satisfactory short-term clinical results but no relevant complications.
