Abstract
Systems and methods for bone to bone, or soft tissue to bone, repairs without knot tying. The repair systems include self-cinching constructs which are tensionable and which include a flexible strand with a knotless, adjustable loop with at least one splice and a shuttle/pull device attached to the flexible strand. A final splice is formed by pulling on the shuttle/pull device subsequent to the knotless, adjustable loop being assembled with or secured to tissue (for example, a soft tissue graft or BTB graft), to allow desired tensioning of the graft to be fixated relative to the bone.
Claims15
A method of tissue repair/reconstruction, comprising:
- attaching a tensionable construct to a bone-tendon-bone (BTB) graft to establish an integrated construct, wherein the tensionable construct includes a fixation device and an adjustable, self-locking, knotless, flexible loop connected to the fixation device,
- wherein a region where two flexible loop portions of the adjustable, self-locking, knotless, flexible loop interlink is located within a hole of a bone block of the BTB graft;
- passing the fixation device through a bone tunnel to position the adjustable, self-locking, knotless, flexible loop within the bone tunnel;
- and
- adjusting a length of the adjustable, self-locking, knotless, flexible loop to secure the BTB graft at least partially within the bone tunnel.
A method of tissue repair/reconstruction, comprising:
- attaching a tensionable construct to a bone-tendon-bone (BTB) graft to establish an integrated construct, wherein the tensionable construct includes a fixation device and an adjustable, self-locking, knotless, flexible loop connected to the fixation device;
- passing the fixation device through a bone tunnel to position the adjustable, self-locking, knotless, flexible loop within the bone tunnel;
- and
- adjusting a length of the adjustable, self-locking, knotless, flexible loop to secure the BTB graft at least partially within the bone tunnel,
- wherein attaching the tensionable construct to the BTB graft includes:
- passing a first looped limb of the adjustable, self-locking, knotless, flexible loop through a hole formed in a bone block of the BTB graft with a needle;
- passing a straight limb of the adjustable, self-locking, knotless, flexible loop through the first looped limb;
- and
- connecting the straight limb to a splicing device of the tensionable construct.
A method of tissue repair/reconstruction, comprising:
- passing a first portion of an adjustable, self-locking, knotless, flexible loop of a tensionable construct through a hole formed in a first bone block of a bone-tendon-bone (BTB) graft, wherein the tensionable construct includes a fixation device attached to the adjustable, self-locking, knotless, flexible loop;
- passing a second portion of the adjustable, self-locking, knotless, flexible loop through the first portion of the adjustable, self-locking, knotless, flexible loop that is passed through the hole of the first bone block;
- splicing the second portion of the adjustable, self-locking, knotless, flexible loop through a third portion of the adjustable, self-locking, knotless, flexible loop to secure the adjustable, self-locking, knotless, flexible loop to the BTB graft;
- passing the fixation device through a bone tunnel to position the adjustable, self-locking, knotless, flexible loop within the bone tunnel;
- and
- adjusting a length of the adjustable, self-locking, knotless, flexible loop to secure the first bone block within the bone tunnel.
