Publication number: 20230248353Abstract: 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.Type: ApplicationFiled: April 20, 2023Publication date: August 10, 2023Inventors: Eric S. ZAJAC, Ricardo ALBERTORIO, Brandon L. ROLLER

Patent number: 11109853Abstract: 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.Type: GrantFiled: April 1, 2019Date of Patent: September 7, 2021Assignee: ARTHREX, INC.Inventors: Eric S.

Patent number: 10285801Abstract: 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.Type: GrantFiled: August 4, 2016Date of Patent: May 14, 2019Assignee: ARTHREX, INC.Inventors: Brandon L.
