LARS人工韧带与自体半腱肌腱联合部分腓骨长肌腱重建后交叉韧带的疗效比较

Efficacy comparison of LARS artificial ligament and autologous semitendinosus combined with partial Peroneus longus tendon reconstructing posterior cruciate ligament

目的比较先进韧带加强系统(LARS)与自体半腱肌腱联合部分腓骨长肌腱重建后交叉韧带(PCL)的临床疗效。方法回顾性分析2014年9月~2016年1月中国医科大学附属盛京医院采用LARS人工韧带(LARS组,30例)及自体半腱肌腱联合部分腓骨长肌腱(自体肌腱组,28例)行单纯PCL重建术58例的临床资料。术前、术后采用KT-1000检查、国际膝关节评分委员(IKDC)评分、Lysholm评分和Tegner评分进行膝关节功能评价。结果 58例均获得随访,术后两组KT-1000检查、IKDC评分、Lysholm评分及Tegner评分较术前均有显著提高,差异有高度统计学意义(P<0.01);除术后LARS组KT-1000优于自体肌腱组(P<0.01),其它各项评分两组之间差异无统计学意义(P>0.05)。结论 LARS人工韧带及自体半腱肌腱联合部分腓骨长肌腱重建后交叉韧带均可取得满意临床疗效,LARS人工韧带可提供更佳的膝关节稳定性。

Objective To compare the effect of ligament advanced reinforcement system （LARS） and autologous semi- tendinosus combined with partial peroneal longus tendon reconstructing posterior cruciate ligament （PCL）. Methods From September 2014 to January 2016, in Shengjsing Hospital of China Medical University, the clinical data of 58 pa- tients who underwent PCL reconstruction surgery with LARS artificial ligament （LARS group, 30 cases） and semitendi- nosus tendon autograft （allograft group, 28 cases） were selected retrospectively analyzed. KT-1000 measurement, Inter- national Knee Documentation Committee （IKDC） scores system, Lysholm knee scores scale and Tegner scores scale be- fore and after surgery were uesd for knee joint function assessment. Results All 58 cases were followed up. Afetr surgery, KT-IO00 results, IKDC scores, Lysholm knee scores and Tegner scores of two groups improved than before syrgery, the differences were statistically significant （P 〈 0.01）; except KT-1000 results of LARS group was better than that of allo- graft group （P 〈 0.01）, there was no statistical difference of the others between two groups （P 〉 0.05）. Conclusion LARS artificial ligament and autologous semitendinosus combined with partial peroneal longus tendon can produce sat- isfactory clinical outcomes in the PCL reconstruction, and LARS artificial ligament can provide a better knee stability.
