GRAFT FIXATION

摘要

A system for graft fixation including ACL graft reconstruction and fixation is presented. The system may comprise a loop fixation device (10) for retaining a tissue graft. The loop fixation device may comprise a graft retention portion (16) and a cortical fixation portion (12, 14) to allow the loop fixation device to rest on the cortical portion of a bone. A tissue graft may pass through a bone tunnel and engage the loop fixation device preventing withdraw of the tissue graft back through the bone tunnel. The system may also include graft fixation within a bone tunnel using a sleeve (210), or tube construct, with a fixation member, or screw (300), to engage a tissue graft within the sleeve.
