Abstract

An adjustable suture-button construct for ligament reconstruction. The construct is a knotless, adjustable, flexible suture loop, a first fixation device (a free or removable slotted button) and optionally a second fixation device (a fixed, non-removable button). Suture ends of the knotless suture loop provide a variable-length graft support that can be adjusted prior to, during, or after deployment of the constructs. The removable, detachable fixation device is provided with attachment feature(s) to permit assembly onto the adjustable loop. The removable, detachable fixation device is attached to the tibia end of the loop construct after the loop construct is passed through the tibial tunnel (i.e., once the loop exits the anterior tibia cortex). If a fixed, non-removable button is employed, the fixed, non-removable button is securely attached (by stitching, for example) to the graft.

First claim

What is claimed as new and desired to be protected by Letters Patent of the United States is:

1. A fixation system for ligament repair, comprising:
an adjustable suture-button construct having a flexible, adjustable, knotless, continuous loop with two adjustable eyesplices that are interconnected for knotless fixation; a first fixation device comprising an oblong button having laterally arranged end slots to attachment to and detachment from the flexible, adjustable, knotless, continuous loop; a second fixation device comprising a round button with six holes secured to the flexible, adjustable, knotless, continuous loop; and a PCL graft secured to the round button by a suture.

2. The fixation system of claim 1 , wherein the adjustable loop is formed of a high strength suture.
