ABSTRACT:
A graft preparation table including a bone block drill guide and a suturing station. The bone block drill guide has a central tunnel and first and second parallel tunnels intersecting opposite sides of the central tunnel and parallel to the central tunnel. A bone plug is longitudinally inserted into the central column so that parallel grooves may be formed in the bone plug by drilling through the first and second parallel tunnels. The suturing station includes a tensioning track and a pair of suture blocks separated along the track. Each suture block includes a chamber for accommodating a bone plug and suture openings on opposite sides of the suture block. The distance between the suture blocks on the tensioning track may be adjusted to achieve the desired tension on the ligament replacement looped about the bone plugs. A stop pin is inserted into each suture block to hold the bone plug in its respective chamber. A needle carrying a suture is inserted through a suturing opening to attach the ligament replacement to the bone plug. The needle pierces the ligament replacement and the bone plug and exits through the suturing opening on the opposite side. Suturing is conducted with the ligament replacement under tension.
