Abstract

This disclosure relates to surgical fixation systems and methods. The surgical fixation systems can include a fixation device and an adjustable loop connected to the fixation device. A reinforcement construct may be integrated with the adjustable loop.

Claims

1. A surgical fixation system, comprising:

a button;

an adjustable loop connected to the button; and

a reinforcement construct integrated with the adjustable loop;

wherein a reinforcement scaffold of the reinforcement construct includes a woven, rip-stop pattern that is attached to the adjustable loop;

wherein a suture loop of the reinforcement construct includes a continuous, uninterrupted suture loop that is attached to the reinforcement scaffold;

wherein a needle of the reinforcement construct is attached to the continuous, uninterrupted suture loop.

2. A surgical fixation system, comprising:

a fixation device;

a loop connected to the fixation device; and

a reinforcement construct pre-assembled to the loop and including a reinforcement scaffold attached to the loop and a suture loop attached to the reinforcement scaffold.

3. The system as recited in claim 2, wherein the fixation device is a button.

4. The system as recited in claim 2, wherein the loop is an adjustable loop that includes a first adjustable eyesplice loop received through a first aperture of the fixation device and a second adjustable eyesplice loop received through a second aperture of the fixation device.

5. The system as recited in claim 4, wherein the adjustable loop includes a first free braid strand for adjusting the first adjustable eyesplice loop and a second free braid strand for adjusting the second adjustable eyesplice loop.

6. The system as recited in claim 5, wherein the first free braid strand extends from a first spliced section of the adjustable loop and the second free braid strand extends from a second spliced section of the adjustable loop.

7. The system as recited in claim 2, wherein the reinforcement construct includes a woven, rip-stop pattern.

8. The system as recited in claim 2, wherein the suture loop of the reinforcement construct includes a continuous, uninterrupted suture loop.

9. The system as recited in claim 2, wherein the reinforcement construct includes a needle.

10. The system as recited in claim 9, wherein the needle is a free floating needle that is movable relative to the suture loop.

11. The system as recited in claim 9, wherein the needle is swaged to the suture loop.

12. The system as recited in claim 9, wherein the reinforcement construct includes a needle that is attached to the suture loop at an opposite end of the suture loop from the reinforcement scaffold.

13. A method for reinforcing a graft, comprising:

positioning a reinforcement scaffold of a reinforcement construct of a surgical fixation system against a first side of the graft, wherein the reinforcement construct is pre-assembled to an adjustable loop of the surgical fixation system;

positioning the graft through an opening between suture strands of a suture loop of the reinforcement construct;

passing a needle of the reinforcement construct through the reinforcement scaffold and the graft to create a first stitched region;

repositioning the graft through the opening between the suture strands of the suture loop;

repassing the needle through the reinforcement scaffold and the graft to create a second stitched region that is distal to the first stitched region;

passing the suture loop through an opening of the adjustable loop; and

repassing the needle through the reinforcement scaffold and the graft to create a third stitched region that is between the first stitched region and the second stitched region.

14. The method as recited in claim 13, comprising:

securing the graft to a graft workstation prior to positioning the reinforcement scaffold.

15. The method as recited in claim 13, wherein positioning the reinforcement scaffold includes:

aligning a distal aspect of the reinforcement scaffold with a distal aspect of the graft.

16. The method as recited in claim 13, comprising:

passing the needle through a proximal portion of the graft before positioning the graft through the opening and creating the first and second stitched regions.

17. The method as recited in claim 13, comprising:

clamping the reinforcement scaffold to the graft prior to positioning the graft through the opening and creating the first and second stitched regions.

18. The method as recited in claim 13, comprising:

cutting off the needle from the suture loop; and

tying the suture strands of the suture loop into a knot.

19. The method as recited in claim 13, wherein the needle is inserted in a direction from the first side to a second side of the graft each time the needle is passed through the reinforcement scaffold and the graft.

20. The method as recited in claim 13, wherein the reinforcement construct is already attached to the adjustable loop when the surgical fixation system is removed from its sterile packaging.
