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.
Claims16
A fixation system for tissue reconstruction, comprising:
- a fixation device;
- a knotless tensionable loop construct attached to the fixation device and having two flexible loops and two splices, at least one of the two flexible loops having an adjustable length, wherein the two flexible loops are interlinked such that a first loop of the two flexible loops passes through an opening established by a second loop of the two flexible loops and the second loop passes through an opening established by the first loop wherein the two flexible loops and the two splices are formed from a same flexible strand;
- and
- a graft connected to the tensionable loop construct, wherein at least one of the two flexible loops is passed through a bone block of the graft wherein a region where the two flexible loops are interlinked is located within a hole of the bone block.
A surgical system, comprising:
- a fixation device;
- a loop construct connected to the fixation device and including a first adjustable loop, a first splice, a second adjustable loop, and a second splice, wherein the second adjustable loop is interlinked with the first adjustable loop such that the first adjustable loop passes through an opening established by the second adjustable loop and the second adjustable loop passes through an opening established by the first adjustable loop wherein the first adjustable loop, the first splice, the second adjustable loop, and the second splice are formed from a same flexible strand;
- and
- a graft connected to the loop construct such that at least one of the first adjustable loop and the second adjustable loop passes through a hole in a bone block of the graft wherein a region where the two flexible loops are interlinked is located within the hole of the bone block.
