摘要目的 比较关节镜下采用髌韧带和六股异体腘绳肌腱单束重建前交叉韧带的临床效果.方法 回顾性分析2006年10月至2009年12月我科采用关节镜下异体移植物单束重建前交叉韧带(ACL)的108例患者的临床资料,其中六股异体腘绳肌腱58例(腘绳肌腱组),异体髌韧带50例(髌韧带组).术后应用Lachman和pivot-shift试验以及KT-1000评估膝关节稳定性,按照国际膝关节评分委员会(IKDC)、Lysholm膝关节评分评价膝关节功能.结果 术后患者随访时间12～38个月,平均为28.6个月.腘绳肌腱组KT-1000检查示双侧膝关节前向松弛度差异为(1.2±1.2)mm,显著小于髌韧带组(1.8±1.5)mm,差异具有统计学意义(P＜0.05).腘绳肌腱组轴移试验阴性55例(94.8%),阳性3例(5.2%),髌韧带组阴性41例(82.0%),阳性9例(18.0%),差异具有统计学意义(P＜0.05).术后腘绳肌腱组和髌韧带组IKDC评分为(90±5)分和(89±5)分,Lysholm评分为(94±5)分和(93±6)分,两组比较差异无统计学意义(P＞0.05).结论 关节镜下单束重建前交叉韧带采用六股异体腘绳肌腱较髌韧带能够明显提高膝关节稳定性.

abstractsObjective To compare the outcome of arthroscopic single-bundle anterior cruciate ligament(ACL)reconstruction with six-strand hamstring tendon and patellar tendon allograft.Methods From October 2006 to December 2009,108 patients with arthroscopic single-bundle ACL reconstruction were retrospectively reviewed,with 58 patients with six-strand hamstring tendon(Group H),and 50 patients with patellar tendon allograft(Group P).Patients were available for clinical evaluation with KT-1000 arthrometer measurements,Lachman and pivot-shift test,and knee function with the Internationa]Knee Documentation Committee(IKDC),Lysholm scores.Results All the patients were followed up at an average of 28.6 months(range 12-38 months).The average side-to-side difference was lesser for group H(1.2 ± 1.2)mm than group P(1.8 ±1.5)mm(P＜0.05).On the pivot-shift test,55(94.8%)patients were negative and 3(5.2%)were positive in group H,whereas 41(82.0%)were negative and 9(18.0%)were positive in group P,with significant difference between two groups(P＜0.05).All knee function scores were improved postoperatively,without statistically significant difference between the two groups(P＞0.05).Conclusion Arthroscopic single-bundle ACL reconstruction with six-strand hamstring tendon will achieve better knee stability than patellar tendon allograft.
