Abstract
Knotless self-locking constructs and methods of tissue repairs. A flexible coupler creates a plurality of closed, knotless, continuous, adjustable, flexible loops having adjustable perimeters, the loops being located between a loop interconnection and two terminal ends. A weave region having an accordion configuration and a plurality of locking points is provided between each terminal end and each closed, knotless, continuous, adjustable, flexible loop.
Claims14
A surgical construct comprising:
- a fixation device comprising a body with a first surface and an opposing second surface and two passages extending from the first surface to the opposing second surface;
- and
- a self-locking tensionable construct pre-loaded on the fixation device, the self-locking tensionable construct comprising two flexible couplers extending through the two passages of the fixation device and forming at least two flexible, closed, adjustable, knotless loops and a loop interconnection, wherein each of the two flexible couplers has two terminal ends, wherein one of the two terminal ends of each of the two flexible couplers is passed multiple times through the flexible coupler to each form an accordion-type weave region and a plurality of locking points, and wherein the one of the two terminal ends is connected to other of the two terminal ends of each of the two flexible couplers by a suture passing device.
A surgical assembly comprising:
- a fixation device comprising a body with a first surface and an opposing second surface and two passages extending from the first surface to the opposing second surface;
- and
- a self-locking tensionable construct pre-loaded on the fixation device, the self-locking tensionable construct comprising two flexible couplers extending through the two passages of the fixation device and forming at least two flexible, closed, adjustable, knotless loops;
- wherein each of the two flexible couplers has two terminal ends, wherein one terminal end of each of the two flexible couplers is passed multiple times through respective flexible coupler to form an accordion-type weave region and a plurality of locking points, and the other terminal end of each of the two flexible couplers is attached to a needle.

A method of forming a knotless self-locking construct, comprising:
- passing a first flexible coupler and a second flexible coupler through passages of a fixation device to form at least two flexible, continuous, closed, adjustable, knotless loops, wherein each of the first and second flexible couplers has a first end and a second end;
- interconnecting the first flexible coupler with the second flexible coupler to form a loop interconnection, the loop interconnection separating the at least two flexible, continuous, closed, adjustable, knotless loops;
- passing one of the first end and the second end of each of the first and second flexible couplers through the flexible coupler multiple times to each form an accordion-type weave region and a plurality of locking points;
- and
- attaching the other of the first end and the second end of each of the first and second flexible couplers to a needle.
