Tissue fixation device

A method for securing a graft to a bone comprising:

• forming a tunnel in the bone;
• positioning at least a portion of the graft in the tunnel;
• engaging a proximal end of an anchor with a distal end of an elongated tubular anchor sleeve;
• sliding a driver through the anchor sleeve and engaging a cruciate-shaped shaft of the driver to a cruciate-shaped bore defined in the anchor;
• applying torque to the anchor using the driver to drive the anchor into the tunnel while the proximal end of the anchor is engaged to the distal end of the anchor sleeve;
• securing the graft in the tunnel with the anchor;
• removing the driver;
• inserting biological material in the bore of the anchor by passing the biological material through the anchor sleeve;
• and
• removing the anchor sleeve after inserting the biological material into the anchor.
