Abstract

A method for reconstructing a joint according to an exemplary aspect of the present disclosure includes, among other things, fixating at least one suture inside a joint space, retrieving the at least one suture from inside the joint space, passing the at least one suture through a graft at a location external to the joint space, shuttling the graft into the joint space, and fixating the graft using the at least one suture.

First claim

What is claimed is:

1. A method for reconstructing a joint, comprising:
inserting a first suture anchor and a second suture anchor into a first bone of the joint;
inserting a third suture anchor and a fourth suture anchor into a second bone of the joint;
measuring a first distance between the first suture anchor and the second suture anchor;
measuring a second distance between the first suture anchor and the third suture anchor;
subsequent to the measuring, sizing a graft to a size indicated by at least the first distance and the second distance;
retrieving a first suture from the first suture anchor, a second suture from the second suture anchor, a third suture from the third suture anchor, and a fourth suture from the fourth suture anchor;
passing the first suture, the second suture, the third suture, and the fourth suture through the sized graft;
shuttling the sized graft to the joint;
fixating the sized graft to the first bone using the first suture and the second suture; and
fixating the sized graft to the second bone using the third suture and the fourth suture.

2. The method as recited in claim 1 , wherein the first bone is a glenoid of a scapula and the second bone is a humerus.

3. The method as recited in claim 1 , comprising:
measuring a third distance between the third suture anchor and the fourth suture anchor; and
wherein the graft is sized based on the first distance, the second distance, and the third distance.

4. The method as recited in claim 1 , comprising:
punching a hole through the graft with a punch prior to passing the first suture through the graft.

5. The method as recited in claim 1 , wherein sizing the graft includes enlarging the graft around its periphery prior to cutting the graft to the enlarged size.

6. The method as recited in claim 1 , comprising:
marking the graft with a marking pin to indicate the location where each of the first suture, the second suture, the third suture, and the fourth suture are to pass through the graft.

7. The method as recited in claim 6 , comprising:
creating a hole at each mark on the graft to assist in passing the first suture, the second suture, the third suture, and the fourth suture through the graft.

8. The method as recited in claim 7 , wherein creating the hole at each mark includes punching a hole through each of the marks with a punch.

9. The method as recited in claim 6 , wherein retrieving the sutures includes:
grasping the first suture from the joint;
pulling the first suture away from the joint;
passing the first suture through the graft;
repeating the grasping, pulling and passing steps with each of the second suture, the third suture, and the fourth suture; and
shuttling the graft to the joint using the first suture, the second suture, the third suture, and the fourth suture.

10. The method as recited in claim 1 , wherein fixating the graft to the first bone includes tying a knot in the first suture.

11. The method as recited in claim 1 , wherein reconstructing the joint includes reconstructing a superior capsule of a shoulder joint that includes a massive irreparable rotator cuff tear.

12. The method as recited in claim 1 , wherein shuttling the sized graft to the joint includes using a double pulley system to shuttle the sized graft.

13. The method as recited in claim 1 , wherein the graft includes an acellular dermal extracellular matrix.

14. The method as recited in claim 1 , comprising:
exposing a bleeding bone bed at each of the first bone and the second bone prior to inserting the first suture anchor, the second suture anchor, the third suture anchor, and the fourth suture anchor.

15. The method as recited in claim 1 , comprising:
performing a partial closure of a rotator cuff over top of the graft after fixating the graft to the first bone and the second bone,
wherein performing the partial closure includes creating side-to-side margin convergence sutures over the top of the graft, wherein the graft is at least partially visible after creating the side-to-side margin convergence sutures.

16. The method as recited in claim 1 , comprising utilizing a kit for performing the method for reconstructing the joint.

17. The method as recited in claim 16 , wherein the kit includes:
at least six suture anchors each pre-loaded with a suture tape;
the graft; and
disposable drills, drill guides, punches, and taps for inserting the suture anchors.

18. The method as recited in claim 17 , wherein the kit further includes:
an instructional insert with instructive diagrams and a description of a methodology for performing the method for reconstructing the joint.

19. A method for reconstructing a joint, comprising:
inserting a first suture anchor and a second suture anchor into a first bone of the joint;
inserting a third suture anchor and a fourth suture anchor into a second bone of the joint;
measuring a first distance between the first suture anchor and the second suture anchor;
measuring a second distance between the first suture anchor and the third suture anchor;
subsequent to the measuring, sizing a graft to a size indicated by at least the first distance and the second distance;
retrieving a first suture from the first suture anchor, a second suture from the second suture anchor, a third suture from the third suture anchor, and a fourth suture from the fourth suture anchor;
passing the first suture, the second suture, the third suture, and the fourth suture through the sized graft;
shuttling the sized graft to the joint;
fixating the sized graft to the first bone using the first suture and the second suture; and
fixating the sized graft to the second bone using the third suture and the fourth suture,
wherein sizing the graft includes enlarging the graft around its periphery prior to cutting the graft to the enlarged size,
wherein the graft is enlarged by at least 5 millimeters about the periphery.
