Abstract: There is disclosed a customizable system and methods of use for manufacturing and testing a variety of pre-sutured allograft tendon constructs sutured according to a variety of stitching patterns and featuring a variety of tissue lengths and types. One embodiment includes a triple-channel base having first, second, and third longitudinal channels extending between first and second ends of the base, as well as a plurality of tendon-manipulation accessories. Each of the tendon-manipulation accessories includes a locking-base assembly for selectively securing the accessory to the base such that the multiple tendon-manipulation accessories may be secured to the triple-channel base in a variety of custom arrangements suitable for preparing the variety of pre-sutured constructs and/or for pre-tensioning or testing the variety of the pre-sutured constructs. Other embodiments are also disclosed.

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.
