Abstract

An adjustable construct for fixation of a tendon or ligament graft in a tunnel. The construct comprises a flexible, adjustable loop connected to tissue (for example, graft, ligament or tendon). The adjustable loop may be integrated with an additional tissue supporting device (for example, a wedge or a plug). The tissue is secured within a bone socket/tunnel by adjusting the length of the flexible adjustable loop.

First claim

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

1. An ACL construct for fixation within femoral and tibial tunnels, comprising:
a graft positioned at least partially between first and second fixation devices;
a flexible, adjustable loop of flexible material attached to the first fixation device, wherein the flexible, adjustable loop has an adjustable length to allow positioning of the graft within a femoral tunnel and a tibial tunnel,
wherein the flexible, adjustable loop has two splices,
wherein the flexible, adjustable loop is formed by a first adjustable eyesplice loop and a second adjustable eyesplice loop that are interconnected at an interconnection where the first adjustable eyesplice loop passes through and interlocks with the second adjustable eyesplice loop, the interconnection and the two splices being located on the opposite ends of the flexible, adjustable loop, and
wherein the graft is passed through the flexible, adjustable loop.

2. The ACL construct of claim 1 , wherein the graft is further looped over the flexible, adjustable loop to form a double bundle construct.

3. The ACL construct of claim 1 , wherein the first fixation device is a button and the second fixation device is an interference device.

4. The ACL construct of claim 3 , wherein the button is adapted for engagement on the femur and is adapted to secure the graft within the femoral tunnel, and wherein the interference device is adapted to secure the graft within the tibial tunnel.

5. The ACL construct of claim 1 , wherein the graft is selected from the group consisting of tendon, ligament, synthetic material, and bone.
