Abstract
Methods for tissue repairs with surgical constructs having cinch loops and stoppers that do not require tying of knots are disclosed. A surgical construct includes a loop with a racking hitch terminating in a single tail. Mechanical pressure is applied to the single tail to deform an area of the surgical construct and form a bulge that acts as a stopper. A ferrule with internal features can be attached to a cerclage construct adjacent a racking hitch to act as a stopper and prevent the cerclage construct from loosening.
Claims19
A method of tissue repair comprising:
- passing a flexible construct through or around tissue to be repaired;
- passing a tail of the flexible construct through a loop of the flexible construct to form a cinch;
- and
- forming a locking mechanism adjacent the cinch to prevent passage of the tail back through the loop,
- wherein forming the locking mechanism includes applying a mechanical compression force on the flexible construct so that a core forms a bulge that protrudes outward of a braid of the flexible construct and thereby creates an obstruction for preventing loosening of the flexible construct through the loop.
A method of tissue repair comprising:
- passing a flexible construct through or around tissue to be repaired;
- forming a racking hitch in the flexible construct;
- passing a tail of the flexible construct through the racking hitch;
- tensioning the tail to cinch the flexible construct around the tissue;
- and
- applying a mechanical pressure at a region of the flexible construct adjacent to the racking hitch to form a bulge that functions as a stopper for preventing the tail from sliding back through the racking hitch,
- wherein applying the mechanical pressure includes applying a compression force to the flexible construct to provide a crimped area that causes a core to protrude through and beyond an outer surface of a braid of the flexible construct and thereby form the bulge.
