[目的]探讨保留残余的束支以及断端纤维进行前交叉韧带重建的方法及意义.[方法]关节镜下证实前交义韧带损伤47例,其中部分束支断裂15例,完全断裂26例,韧带松弛6例.对前交叉韧带部分损伤的束支或韧带松弛者予以保留,对完全断裂的残端不做清理,采用自体四股腘绳肌腱单束重建前交叉韧带,股骨端采用Rigid-Fix固定,胫骨端采用IntraFix固定.[结果]术后均得到随访,时间12～24个月,平均19个月,术后膝关节稳定性增强.Lysholm膝关节功能评分,术前平均68.6分,术后平均94.9分,较术前提高26.3分.Lachman试验阴性43例,弱阳性3例,阳性1例.按lnsail膝关节疗效评定标准,优38例,良9例.[结论]保留残余韧带重建ACL,有助于移植肌腱再血管化和本体感觉的建立,有利于维持膝关节的稳定性.“,”[Objective]To investigate the technique and significance of arthroscopic anterior cruciate ligament(ACL)recon-struction with the remaining bundle and ruptured fiber.[Method]In 47 cases of ACL rupture verified with arthroscopy,there were 15 cases of partial disruption,26 cases of complete disruption,and 6 cases of ligament flabby.ACLs were reconstructed with single bundle of autogenous quadrupled hamstring tendons under arthroscopy without remove of the remaining bundle or remnants of ACL.The femur tunnel Was fixed by the Rigid Fix system,and the Intrafix system was used to fix the tibia tunnel.[Result]All of 47 cases were followed up for an average of 19 months(ranged from 12 to 24 months).The stabilization was strengthened after operation.Lysholm knee function score increased by 26.3 scores,from average 68.6 scores of preoperation to average 94.9 scors after operation.Lachman test was negative in 43 cages.weakly positive in 3 cases and positive in 1 case.According to Insall knee therapeutic effect evaluation criterion,38 cases achieved excellent results and 9 case8 achieved good results.[Conclusion]Ar-throscopie reconstruction of ACL with the remaining bundle preserving technique could facilitate revasculization and reinnervation of the reconstructed ligament and maintain stability of knee joint.
