摘　　要：目的:比较关节镜下后交叉韧带(posterior cruciate ligament,PCL)保残重建术中应用先进韧带加强系统(ligament advanced reinforcement system,LARS)韧带与自体腘绳肌腱加高强线的临床效果。方法:选择2019年8月至2021年12月行关节镜下PCL保残重建术治疗的96例单纯PCL损伤,其中男78例,女18例;年龄20~56(32.50±8.68)岁;左侧40例,右侧56例。根据术中移植物不同分为两组。LARS韧带保残重建组(LARS韧带组)52例,其中男42例,女10例;年龄(31.84±8.62)岁;身体质量指数(body mass index,BMI)为(24.73±2.29)kg·m^(-2);采用7 mm LARS韧带保残重建PCL。自体腘绳肌腱加高强线组(自体肌腱组)44例,其中男36例,女8例;年龄(33.06±8.99)岁;BMI为(23.52±2.16)kg·m^(-2);采用4股腘绳肌腱加3根爱惜邦缝线加强技术保残重建PCL。术后3、6、12个月通过KT-1000测量膝关节的松弛度客观评价膝关节的稳定性,采用Lysholm、Tegner、国际膝关节文献委员会(International Knee Documentation Committee,IKDC)评分进行主观评分评价膝关节的功能。收集两组患者术前及术后3、6、12个月时随访的数据,比较两组患者术后康复情况及韧带松弛度的差异性。结果:96例患者获得随访,时间为12个月。膝关节KT-1000测量值自体肌腱组及LARS韧带组术前[(10.73±1.46)分vs(10.55±1.53)分]、术后6个月[(3.02±0.75)分vs(2.35±0.60)分]、12个月[(3.77±1.76)分vs(2.44±0.60)分],术后6、12个月组间比较差异有统计学意义(P<0.05);术后3个月,两组比较,差异无统计学意义(P>0.05)。自体肌腱组、LARS韧带组术前及术后12个月Lysholm总分[(40.6±16.8)、(91.25±6.35)分vs(51.92±18.52)、(92.35±5.30)分],Tegner评分[(1.8±0.7)、(5.8±0.6)分vs(1.7±0.8)、(5.7±0.7)分],IKDC总分[(54.50±6.33)、(83.90±3.93)分vs(54.40±4.24)、(83.62±3.64)分],术后12个月与术前比较,差异均有统计学意义(P<0.05)。自体肌腱组与LARS韧带组术后3、6个月,Lysholm总分[(65.86±11.54)、(74.60±6Objective To compare the clinical efficacy of ligament advanced reinforcement system(LARS)and autogenous hamstring tendon plus high-strength suture in arthroscopic reconstruction of posterior cruciate ligament(PCL).Methods A total of 96 patients with simple PCL injury treated with arthroscopic posterior cruciate ligament reconstructive surgery admitted to our hospital between August 2019 and December 2021 were selected for complete follow-up.There were 78 males and 18 females,40 cases of left leg and 56 cases of right leg,the aged from 20 to 56 years old with an average of(32.50±8.68)years old.The transplants were divided into two groups:LARS group(52 cases)and autogenous hamstring tendon plus high-strength suture group(44 cases).In the LARS group,there were 42 males and 10 females;with an average age of(31.84±8.62)years old;body mass index(BMI)was(24.73±2.29)kg﹒m^(-2);7 mm LARS was used to reconstruct PCL.In the autologous tendon group,there were 36 males and 8 females,with an average age of(33.06±8.99)years old,BMI was(23.52±2.16)kg·m^(-2),and the PCL was reconstructed with four strands of hamstring tendons and three pieces of Ethibond suture.All patients underwent functional rehabilitation guided exercise and were followed up regularly after surgery to objectively evaluate the stability of the knee joint by KT-1000 measurement of knee relaxation,and subjective evaluation of knee function by Lysholm score,Tegner score,and International Knee Documentation Council (IKDC) score. Data from preoperative,3,6,and 12 month follow-up were collected and analyzed by SPSS software to compare postoperative recovery and ligament relaxation between the two groups of patients. Results Ninety-six patients were followed up for 12 months. KT-1000 measurement of knee joint in autogenous tendon group and LARS group before operation [(10.73±1.46) points vs (10.55±1.53) points],6 months after operation[(3.02±0.75) points vs (2.35±0.60) points],12 months after operation[(3.77±1.76) points vs (2.44±0.60) points].
