Abstract
Bashti Bone Plug Technique (BBPT) is an implant-less method which can be used in an Anterior Cruciate Ligament (ACL) reconstructive surgery. The technique uses a core bone plug to fix the tendon graft into the bone tunnel. This study investigates the effect of the core bone density on fixation strength in BBPT method. A series of experimental test has been performed to examine the hypothesis of the study. Thirty fresh bovine digital extensor tendon used in three different groups. Sawbones blocks with densities of 160, 240 and 320 kg/m^3 used in substitute of the bone to model the effect of density on the strength of the fixation. The core bone plugs and tunnels created using a custom made...
