Abstract

Methods of attaching a soft tissue to an adjacent bone at a defect site are provided. An adjustable loop region of a flexible construct contained in a bore defined by a fastener is passed through a tissue. The adjustable loop is passed through the tissue. The fastener is passed back through the adjustable loop to fold the adjustable loop upon itself. The fastener is attached to the bone. An adjusting arm on the flexible construct is engaged to reduce the size of the adjustable loop and secure the soft tissue to the bone.

Claims

1. A method of attaching soft tissue to a bone at a defect site, the method comprising:

obtaining a fastener that has a longitudinal axis extending between a proximal end and a distal end of the fastener with an adjustable loop of a flexible construct being offset from a longitudinal interior bore of a fastener, wherein the adjustable loop being offset from the longitudinal interior bore includes the flexible construct;

(i) entering the fastener through a first opening in the proximal end of the fastener which leads to the longitudinal interior bore;

(ii) extending along the longitudinal interior bore;

(iii) extending along a transverse passage in the fastener that connects the longitudinal interior bore to a longitudinal exterior channel that extends along an outer surface of the fastener;

(iv) exiting the fastener through a second opening in a side wall of the fastener; and

(v) extending along the longitudinal exterior channel;

passing the adjustable loop through the soft tissue after releasing the adjustable loop from a driver carrying the fastener;

passing the fastener back through the adjustable loop to fold the adjustable loop upon itself;

fixing the fastener to an area adjacent the defect such that the adjustable loop and a proximal end of the fastener abuts the defect; and

engaging an adjusting arm on the flexible construct to reduce the size of the adjustable loop and to retain the fastener proximal end in abutment with the soft tissue.

2. The method of claim 1, wherein the entirety of the adjustable loop is positionable outside the fastener.

3. The method of claim 1, wherein the defect is an articular cartilage defect.

4. The method of claim 1, wherein the defect is a labral tear.

5. The method of claim 1, further comprising securing the adjustable loop to a proximal end of the fastener with a restriction element.

6. The method of claim 1, further comprising interlacing a plurality of adjustable loops from a plurality of fasteners to form a suture bridge.

7. The method of claim 1, further comprising forming the adjustable loop by passing a first end of a hollow suture through a first opening in the hollow suture, advancing the first end through a passage formed in the hollow suture, and pulling the first end out of a second opening in the hollow suture.

8. The method of claim 7, wherein the passage between the first opening and the second opening is a passage portion and wherein offsetting the adjustable loop from the longitudinal interior bore comprises disposing the passage portion in the longitudinal interior bore, in the transverse passage, and in the longitudinal exterior channel.

9. The method of claim 1, wherein the entirety of the adjustable loop is positioned outside the fastener when passing the adjustable loop through the soft tissue.

10. The method of claim 9, further comprising inserting the fastener into a bore formed in the bone using a driver on which the fastener is mounted, wherein the fastener mounted on the driver includes:

the adjusting arm extending through the driver inside a hollow shaft of the driver, and the adjustable loop extending outside the driver along an exterior surface of the hollow shaft.

11. A method of attaching soft tissue to a bone at a defect site comprising:

forming a hole in the bone;

positioning a driver carrying a fastener and a flexible construct having an adjustable loop adjacent to the hole in the bone;

releasing the adjustable loop that is offset from a bore defined by the fastener from the driver, wherein said releasing the adjustable loop includes releasing the adjustable loop from being removeably secured to the driver, and wherein the adjustable loop being removeably secured to the driver includes the adjustable loop contacting the driver;

passing the adjustable loop through the soft tissue after said releasing;

passing the fastener back through the adjustable loop to fold the adjustable loop upon itself;

inserting the fastener in the hole in the bone; and

pulling an adjusting arm of the flexible construct to reduce the size of the adjustable loop and secure the soft tissue to the bone.

12. The method of claim 11, wherein the fastener is inserted in the hole in the bone with the driver, wherein the adjustable loop being offset includes the flexible construct extending:

into the fastener through an opening in a proximal end of the fastener, along a longitudinal interior bore in the fastener, through a transverse passage in the fastener that connects the longitudinal interior bore in the fastener to a longitudinal exterior channel in the fastener, and along the longitudinal exterior channel, and wherein releasing the adjustable loop includes releasing the adjustable loop from an adjustable loop mount located on an exterior of the driver.

13. The method of claim 11, wherein releasing the adjustable loop that is offset from the bore defined by the fastener further includes releasing the adjustable loop that is offset from the bore defined by the fastener in an exterior channel in the fastener that is connected to the interior bore by a transverse passage.

14. The method of claim 11, further comprising forming the adjustable loop by passing a first end of a hollow suture through a first opening in the hollow suture, advancing the first end through a passage formed in the hollow suture, and pulling the first end out of a second opening in the hollow suture.

15. The method of claim 11, further comprising securing the adjustable loop to a proximal end of the fastener with a restriction element.

16. The method of claim 15, further comprising regulating movement of the adjusting arm through the bore of the fastener via the restriction element.

17. The method of claim 11, further comprising interlacing a plurality of adjustable loops from a plurality of fasteners to form a suture bridge.

18. The method of claim 11, wherein the defect is an articular cartilage defect.

19. The method of claim 11, wherein the defect is a labral tear.

20. A method of attaching soft tissue to a bone at a defect site comprising:

positioning a driver carrying a fastener and a flexible construct having an adjustable loop adjacent to the defect site;

releasing the adjustable loop that is offset from a bore defined by the fastener from the driver;

passing the adjustable loop through the soft tissue after said releasing;

passing the fastener back through the adjustable loop to fold the adjustable loop upon itself;

fixing the fastener to the bone at the defect site; and

engaging an adjusting arm on the flexible construct to reduce a size of the adjustable loop to secure the soft tissue to the bone after fixing the fastener to the bone.

21. The method of claim 20, wherein the driver carrying the fastener includes:

the adjusting arm extending through the driver inside a hollow shaft of the driver, and the adjustable loop extending outside the driver along an exterior surface of the hollow shaft.

22. The method of claim 21, wherein the adjustable loop extending outside the driver includes the adjustable loop engaging an adjustable loop mount located on an exterior of the driver.

23. The method of claim 22, wherein the adjustable loop being offset includes the flexible construct extending:

into the fastener through an opening in a proximal end of the fastener, along a longitudinal interior bore in the fastener, through a transverse passage in the fastener that connects the longitudinal interior bore in the fastener to a longitudinal exterior channel in the fastener, and along the longitudinal exterior channel.
