Abstract:
[Objective]To explore the biomechanical effects of preserving the remnants in anterior cruciate ligament(ACL) reconstruction under sealing the bone tunnel.[Method]Twelve skeletally matured New Zealand white rabbits underwent ACL reconstruction with preserving the remnants and sealing the bone tunnels on one knee randomly,the opposite knee was served as the paired control―ACL reconstruction with removing the remnants and sealing the bone tunnels.Rabbits were sacrificed at 12 weeks.The maximum loading of the femur-graft-tibia complexes were determined in 858 Mini BionixⅡtestor,and the rupture site was observed.[Result]The mean maximum load at 12 weeks was (23.46?7.4)N in the preserving remnants group,(18.63?4.26)N in the removing remnants group,the maximum load in the expermental group was 126% of the control.There was significant difference between two groups (t=3.058,P
