Apparatus and method for reconstructing a ligament

A method of revising a graft ligament in a bone tunnel comprising:

• unpinning a graft ligament support block from within a bone tunnel in a host bone by engaging an internal tapped hole in a transverse fixation pin with a removal tool and withdrawing the transverse fixation pin from a transverse fixation pin hole in the graft ligament support block and from a transverse tunnel in the host bone, the graft ligament support block including a body defining a longitudinal axis, the body having a trailing end that tapers radially inward along the longitudinal axis for facilitating retraction of the graft ligament support block from the bone tunnel and sculpted away portions extending along the longitudinal axis for receiving the graft ligament;
• retracting the graft ligament support block from the bone tunnel to create a vacated bone tunnel by pulling back on the graft ligament attached to the graft ligament support block;
• advancing a graft ligament support block within the vacated bone tunnel using an installation tool secured within a pair of recesses formed on a proximal-most end of the graft ligament support block;
• and
• pinning the graft ligament support block within the bone tunnel by advancing the transverse fixation pin along the transverse tunnel in the host bone and into a transverse fixation pin hole in the graft ligament support block.
