Abstract
There is disclosed an apparatus and method of manufacture relating to a pre-sutured, high-strength allograft tendon construct. One embodiment of the allograft tendon construct includes first and second tendon lengths that are positioned longitudinally in parallel to one another. A whip stitched pattern secures the first and second tendon lengths at a free end, forming a stitched end portion that abuts an unstitched middle portion. The whip stitched pattern includes a plurality of sutures that originate adjacent to the free end and progress or advance inward toward the unstitched middle portion. A multiple knot bundle is applied immediately prior to a final suture, such that the final suture loops about the multiple knot bundle and locks the multiple knot bundle in place beneath the final suture. Other embodiments are also disclosed.
