Abstract

Knotless, all inside self-locking constructs and methods of tissue repairs are disclosed herein. A flexible strand can be passed through a friction-based locking mechanism to create a plurality of closed, knotless, continuous, adjustable, flexible loops having adjustable perimeters, the loops being located between a loop interconnection and two terminal ends.

Claims (21)

1 . A surgical construct, comprising:

a flexible strand having a first end and a second end;

a loop interconnection between the first end and the second end; and

a locking mechanism between the loop interconnection and the first end and the second end,

wherein the first end is passed through the locking mechanism multiple times to form a first closed, adjustable, continuous, flexible loop with an adjustable length and a first weave region having an accordion-type configuration.

2 . The surgical construct of claim 1 , wherein the locking mechanism is a friction-based mechanism.

3 . The surgical construct of claim 1 , wherein the locking mechanism is a Chinese finger trap, a flexible coupler, or a suture ring.

4 . The surgical construct of claim 1 , wherein the second end is passed through the locking mechanism multiple times to form a second closed, adjustable, continuous, flexible loop with an adjustable length and a second weave region having an accordion-type configuration.

5 . The surgical construct of claim 4 , wherein the second end is passed through the first closed, adjustable, continuous, flexible loop to form the loop interconnection, and subsequently through the locking mechanism.

6 . The surgical construct of claim 5 , wherein each of the first and second closed, adjustable, continuous, flexible loops is located between one of the first and second ends and the loop interconnection.

7 . The surgical construct of claim 5 , wherein each of the first and second weave regions is located between one of the first and second ends and one of the first and second closed, adjustable, continuous, flexible loops.

8 . The surgical construct of claim 1 , wherein the flexible strand is attached to one or more fixation devices.

9 . The surgical construct of claim 1 , wherein the flexible strand is a combination of flat and round suture.

10 . The surgical construct of claim 1 , wherein the construct is self-locking and tensionable.

11 . The surgical construct of claim 1 , wherein the flexible strand is unitary with the locking mechanism.

12 . The surgical construct of claim 1 , wherein the locking mechanism is provided as a separate structure from the flexible strand.

13 . A self-locking tensionable construct for tissue repair comprising:

a flexible strand extending through a friction-based locking mechanism and forming two flexible, continuous, closed, adjustable, knotless loops each having an adjustable length; a loop interconnection; and two terminal ends, wherein each terminal end is passed at least once through the friction-based locking mechanism to each form a plurality of locking points.

14 . The self-locking tensionable construct of claim 13 , wherein each terminal end is configured to be pulled to lock the surgical construct.

15 . The self-locking tensionable construct of claim 13 , wherein each terminal end is configured to be pulled to decrease a length of each of the two flexible, continuous, closed, adjustable, knotless loops.

16 . The self-locking tensionable construct of claim 13 , wherein the tissue repair is rotator cuff repair, AC joint repair, syndesmosis repair, Achilles tendon repair, patellar tendon repair, ACL/PCL reconstruction, hip and shoulder reconstruction, AC joint reconstruction, syndesmosis reconstruction, quad/patellar tendon rupture repair, or hallux-valgus repair.
