Abstract

Systems and methods for preparing a ligament graft construct for a ligament reconstruction or repair procedure are provided. In general, the described techniques utilize a reinforcement material having at least one suture tail extending therefrom. The reinforcement material is a ribbon or a ribbon-like flattened portion attached to or integrally formed with the at least one suture tail. To prepare a tissue repair construct, the reinforcement material is positioned on a first surface of a graft to extend from an end thereof and the at least one suture tail, coupled to a needle, is repeatedly passed through the reinforcement material and the surface of the graft to a second surface of the graft, and around a side portion of the graft to thereby create multiple suture loops. The tissue repair construct can be formed on each end of the graft.

Dependent claims

A tissue repair construct, comprising:

a graft material having first and second ends;
a reinforcement material positioned on a first surface of the graft material adjacent to the first end of the graft material, the reinforcement material having a first end adjacent to the first end of the graft material and a second end remote from the first end of the graft material;
and
a suture integrally formed with the reinforcement material and having first and second suture tails extending from a same end of the reinforcement material and secured to the graft material, the first and second suture tails forming multiple loops along a length of the reinforcement material and the graft material, each loop including a segment of the first and second suture tails extending through the reinforcement material and through the first surface of the graft material at a first position to a second surface of the graft material, around a side portion of the graft material and through the reinforcement material and the first surface of the graft material at a position longitudinally spaced from the first position and exiting the second surface of the graft material,
wherein at least one of the first and second suture tails freely extends from the first end of the graft material, and wherein the reinforcement material is only formed from a portion of the suture.
