  • Publication number: 20230248353
    Abstract: An adjustable, knotless button/loop construct for fixation of ankle syndesmosis tibio-fibular diastasis and an associated method of ankle repair using the same. The knotless construct comprises a pair of buttons attached to a flexible, continuous, self-cinching, adjustable loop integrated with two splices that are interconnected. The knotless construct is passed through fibular and tibia tunnels and the buttons are secured on the cortical surfaces of tibia and fibula. One of the buttons (for example, an oblong button) is secured on the medial side of the tibia by passing the button and the flexible, adjustable loop though the fibular and tibia tunnels and then flipping and seating the button outside the tibia. The length of the flexible adjustable loop is adjusted so that the second button (for example, a round button) is appropriately secured on the lateral fibula.

  • Publication number: 20220117721
    Abstract: An adjustable construct for fixation of a tendon or ligament graft in a tunnel. The construct comprises a flexible, adjustable loop connected to tissue (for example, graft, ligament or tendon). The adjustable loop may be integrated with an additional tissue supporting device (for example, a wedge or a plug). The tissue is secured within a bone socket/tunnel by adjusting the length of the flexible adjustable loop.

  • Patent number: 11109853
    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.

  • Patent number: 10285801
    Abstract: An adjustable, knotless button/loop/needle construct for fixation of cranial cruciate ligament deficient stifle. The adjustable, knotless construct includes two fixation devices (for example, two buttons) and at least one flexible, adjustable loop attached to at least one of the fixation devices (e.g., the buttons). Preferably, a needle is attached to each of the fixation devices (e.g., the buttons). The adjustable, knotless construct has an adjustable loop length and allows adjustment in one direction while preventing or locking the construct from loosening in the opposite direction, due to applied tensile forces. The construct and technique of the present invention provides an improved knotless system for cruciate ligament repair.
