Abstract：Objective To evaluate the methods and therapeutic effects of the anterior cruciate ligament(ACL)reconstruction with remnant preservation and no preservation under arthroscopy.Methods A total of 48 patients with ACL injury in the Wuhan General Hospital of the Chinese People's Liberation Army Command from Jun.2012 to Dec.2015 were enrolled in this study.They received the ACL reconstruction by using hamstring tendon autograft fixed with bioabsorbable interference screw.20 patients were treated with ACL reconstruction with remnant preservation,while 28 patients were treated with ACL reconstruction without remnant preservation.All the patients were followed up with a mean period of 24 months.Each patient was evaluated using the following variables:forward distance measured by KT-2000,Lysholm knee score,the threshold index of perception under passive movement.Results During the follow-up of 24 months,the forward distance by KT-2000 3,6 months after operation in the remnant preservation group was significantly better than that of the non preservation group at the same time(T=5.290,P=0.000;T=3.754,P=0.000).The Lysholm score was apparently higher in the remnant preservation group than in the non preservation group 12,24 months after surgery(T=3.187,P=0.003;T=3.781,P=0.000).The threshold index of perception under passive movement in the remnant preservation group was significantly better than that of the non preservation group 12,24 months after operation(T=4.229,P=0.000;T=3.105,P=0.003).Conclusion Remnant preservation under arthroscopy in ACL reconstruction can provide better recovery of the knee joint movement function after the surgery than non preservation.
