Abstract
A graft ligament is looped through a graft hole in a graft ligament support block, and the graft ligament support block is mounted to an installation tool. Then the installation tool is used to advance the graft ligament support block into a bone tunnel, with the two free ends of the looped graft ligament extending back out the bone tunnel. Next, a transverse tunnel is formed in the host bone, with the transverse tunnel being aligned with a transverse fixation pin hole in the graft ligament support block. Then the graft ligament support block is secured in place by pinning the graft ligament support block within the tunnel, i.e., by advancing a transverse fixation pin along the transverse tunnel and into the transverse fixation pin hole in the graft ligament support block. Then the installation tool is detached from the graft ligament support block and withdrawn from the surgical site.
