Comparison of the Suspensory and Double Cross-pin Graft Fixation after ACL Reconstruction Using Hamstring Autograft / 中国运动医学杂志

ABSTRACT

Objective To compare the clinical results of Endobutton and Rigidfix graft fixation at the femoral tunnel after ACL reconstruction with hamstring autografts.Methods 48 patients accepting ACL reconstruction with hamstring autografts were retrospective studied.According to different fixation adopted at the femoral tunnel,they were divided into group A(24 patients,with Rigidfix cross pin)and group B(24 patients,with Endobutton).All cases were fixed with Intrafix interference screw and Spiked Washer screw at the tibial tunnel.The average follow-up time was 27 months.KT-1000 arthrometric measurement and the IKDC,Lysholm,Tegner scores were used for evaluation.The diameter of bone tunnel was also measured by MRI.Results Tunnel widening were found in both groups,but the increase of both the femoral and tibial tunnels in group B were significantly greater than group(P
