Abstract

A method for coupling tissue with a flexible member including a tail and a self-locking construct coupled to the tail. The self-locking construct includes a first loop and an adjustable second loop coupled thereto. The method includes implanting an anchor in bone. The anchor is slidably mounted to the tail. The tail is positioned relative to the tissue. An end of the tail is inserted through the first loop. The tail is passed through the first loop. The second loop is pulled into the anchor. The self-locking construct is positioned relative to the tissue. The self-locking construct is tightened against the tissue by pulling on an end of the self-locking construct.

Claims

1. A method for coupling tissue with a flexible member including a tail and a self-locking construct coupled to the tail, the self-locking construct including a first loop and an adjustable second loop coupled thereto, the method comprising:

implanting an anchor in bone, the anchor slidably mounted to the tail;

positioning the tail relative to the tissue;

inserting an end of the tail through the first loop;

passing the tail through the first loop, pulling the adjustable second loop into the anchor, and positioning the self-locking construct relative to the tissue; and

tightening the self-locking construct against the tissue by pulling on an end of the self-locking construct,

wherein positioning the tail includes positioning the tail such that the tail passes through a first tissue portion and a second tissue portion to arrange the self-locking construct across the first tissue portion and the second tissue portion, and couple the first tissue portion to the second tissue portion.

2. The method of claim 1, further comprising positioning the tail relative to the tissue one of before or after implanting the anchor in bone.

3. The method of claim 1, wherein positioning the tail includes positioning the tail such that the tissue is between a first portion of the tail and a second portion of the tail, and wherein positioning the self-locking construct includes wrapping the self-locking construct around the tissue.

4. The method of claim 1, further comprising tightening the first loop to the adjustable second loop by sliding a first body of the self-locking construct along the self-locking construct to decrease the size of, and adjust, the first loop, and tensioning the adjustable second loop by pulling on the end of the self-locking construct to move the anchor from an expanded position to a collapsed position by flexing the anchor to secure the anchor within the bone.

5. The method of claim 1, wherein the tissue is labrum tissue and the method further includes:

passing a shuttling strand under the tissue with a passer;

pulling the shuttling strand from under the tissue with a grasper;

pulling the shuttling strand through a portal and coupling the shuttling strand to the tail;

pulling the tail under the tissue with the shuttling strand and arranging the tail such that the tissue is generally between a first portion and a second portion of the tail;

forming a bone hole in the glenoid with a drill, the bone hole formed near the tail;

implanting the anchor in the bone hole using an insertion tool;

passing the tail through the first loop outside of the body;

pulling the tail out of the joint space and entirely through the first loop; and

pulling the end of the self-locking construct to tighten the self-locking construct onto the labrum tissue.

6. A method for coupling tissue with a flexible member including a tail and a self-locking construct coupled to the tail, the self-locking construct including a first loop and a second adjustable loop coupled thereto, the method comprising:

implanting an anchor in bone, the anchor slidably mounted to the tail;

passing the tail through the tissue;

inserting an end of the tail through the first loop;

passing the tail through the first loop, pulling the second adjustable loop into the anchor, and positioning the self-locking construct through the tissue; and

tightening the self-locking construct against the tissue by pulling on an end of the self-locking construct.

7. The method of claim 6, further comprising implanting the anchor one of before or after passing the tail through the tissue.

8. The method of claim 6, further comprising passing the anchor through the tissue prior to implanting the anchor in the bone.

9. The method of claim 6, further comprising passing the tail through the tissue from an inner surface to an outer surface of the tissue.

10. The method of claim 6, further comprising passing the tail through the tissue twice, such that the self-locking construct extends through the tissue in a first direction and returns through the tissue in a second direction.

11. The method of claim 6, wherein the anchor is a first flexible anchor, the method further comprising implanting a second flexible anchor in the bone, the second flexible anchor slidably mounted to the tail.

12. The method of claim 11, further comprising implanting the first flexible anchor in the bone medial to the second flexible anchor.

13. The method of claim 11, further comprising implanting a third flexible anchor in the bone, the third flexible anchor slidably mounted to the tail.

14. The method of claim 6, further comprising passing the tail through rotator cuff tissue.

15. The method of claim 6, further comprising tensioning the tissue in the lateral direction by pulling on the end of the self-locking construct.

16. A method for coupling tissue with a flexible member including a tail and a self-locking construct coupled to the tail, the self-locking construct including a first loop and a second adjustable loop coupled thereto, the method comprising:

passing the tail through a first tissue and a second tissue;

inserting an end of the tail through the first loop;

passing the tail through the first loop, pulling the second adjustable loop into and across both the first tissue and the second tissue; and

tightening the self-locking construct against both the first tissue and the second tissue by pulling on an end of the self-locking construct to couple the first tissue to the second tissue.

17. The method of claim 16, wherein the first tissue and the second tissue are separated rotator cuff tissue.

18. The method of claim 16, wherein the first loop is adjustable, and further comprising closing the first loop onto the second adjustable loop of the self-locking construct to secure the first loop to the second adjustable loop and retain the first tissue in contact with the second tissue.

19. The method of claim 18, further comprising passing the entire tail through the first loop and pulling the end of the suture construct to decrease the size of the second adjustable loop.
