Autograft tunnel

Type of graft, possible graft motion, and hxation methods have been shown to directly affect time-course and quality of graft-tunnel healing. Those known to have a slower healing process are the soft-tissue autograft and... 

Shino et al. [33] introduced the triple-bundle ACL reconstraction technique in which the three bundles of the ACL are individually reconstructed with hamstring tendon autografts. This technique may have much greater potential to closely mimic not only the morphology but also the biomechanical behavior of the native ACL [34-36]. Clinically, immediate postoperative stability was better in the triplebundle procedure than in the double-bundle reconstruction [37]. In addition, Suzuki et al. [38] reported that laxity match pretension at 15° knee flexion became smaller in the triple-bundle reconstruction than in double-bundle reconstruction. The enlarged contact area between the graft and the tunnel wall in the three tibial tunnels might have contributed to this improved biomechanical performance.
