Method and apparatus for forming a self-locking adjustable loop
An apparatus can include a first flexible member having first and second ends and a first body extending therebetween that defines a first passage portion. A second flexible member can include first and second ends and a second body extending therebetween that defines a second passage portion. The first end of the first flexible member can pass into and through the second passage portion in a first direction such that the first end extends outside of the second passage portion. The first end of the second flexible member can pass into and through the first passage portion in a second direction such that the first end of the second flexible member extends outside of the first passage portion to form a self-locking adjustable flexible member construct. Applying tension to the first ends can draw the passage portions and corresponding second ends toward each other.
