Abstract:
[Objective]To compare the early clinical outcome of ACL reconstruction using the ligament advanced reinforcement system and the ?-ray irradiation allograft.[Method]From January 2006 to January 2008,55 cases of ACL reconstruction were studied.According to the indication of LARS ligament and allograft,suggestion from surgeon and patient's aspiration,one of them were chosen as grafts for ACL reconstruction,including 25 LARS ligaments with titanium screw fixation and 19 allografts with absorptive screw fixation.After reconstruction,both groups of patients carried on functional exercise.Each patient was evaluated with Lysholm-Tegner score and KT-2000 measurements preoperatively and postoperatively at 3 months,6 months,9 months,12 months,15 months and 18 months.[Result]Fifty-two cases were followed up,3 cases were dismissed.The Lysholm -Tegner score in cases using the LARS ligament were higher than that in cases using the allograft 3 months post-operation,6 months post-operation,9 months post-operation.Contemporary comparison of the score gap between the LARS ligament group and the allograft group showed a trend of decrease.During the follow up,the allograft group displayed significantly more laxity in KT-1000 measurements at all time points than the LARS ligament group.And the measurements gap between the two groups showed a trend of increase.[Conclusion]The knee anterior-posterior stability of the patients using the LARS ligament were better than that of patients using the allograft.The knee function of the patients using the LARS ligament recovered earlier than that of patients using allograft at nonage,but long-term effect is almost the same.
