  • Publication number: 20120265298
    Abstract: A method and construct for joint repair in which attachment of a double bundle graft ligament approximates anatomic orientation using interference fixation in a single bone tunnel. The double bundle graft features separable strands. A threaded screw is inserted between the separable strands and provides interference fixation of the graft against radially opposing walls defining the bone tunnel. Attachment of the graft using separated strands more closely approximate the configuration of the native ligament. The resulting reconstruction exhibits mechanical functionality that more accurately mimics that of the intact joint, with a minimum of associated tissue morbidity.

    Abstract: The ability to advance soft tissue into bone without externalizing it is considered an improvement for those knowledgable in the art of soft tissue fixation into bone. The above device/implant fixates soft tissue directly, then allows for fixation through a bony hole or aperture into a tunnel or void. It does not require interference fixation (eg. with a screw, or similar implant that fills a bony tunnel with soft tissue interposed). However, it does not preclude subsequent fixation that relies on interference fixation. The claims of this application disclosure for direct soft tissue fixation and subsequent bony fixation using the features of the described device/implant and insertor, as described in detail, are novel in this setting.

    Abstract: A soft tissue fixation system, most typically applicable to orthopedic joint repairs, such as anterior cruciate ligament (ACL) knee repair procedures, comprises an implant which is placeable in a tunnel disposed in a portion of bone, wherein the tunnel is defined by walls comprised of bone. A first member is deployable outwardly to engage the tunnel walls for anchoring the implant in place in the tunnel, and a second member is deployable outwardly to engage tissue material to be fixed within the tunnel. The second member also functions to move the tissue material outwardly into contact with the tunnel walls to promote tendon-bone fixation. Extra graft length is eliminated by compression of the tendon against the bone at the aperture of the femoral tunnel, which more closely replicates the native ACL and increases graft stiffness. The inventive device provides high fixation of tendon to bone and active tendon-bone compression.

  • Patent number: 8137400
    Abstract: A fixing tool used in a ligament reconstruction operation includes a fixing member having a main body part provided with a through-hole and two spike parts which can be stricken into the bone and a fixing screw. The fixing screw includes a shaft part having a self-tap portion and a male screw portion, a head part, and a lumen. The fixing screw can be screwed into the bone plug in a state where a guide pin pierced into the bone plug penetrates the lumen of the fixing screw and a pulling member mounted to the bone plug and extended from the bone tunnel is being pulled. The fixing screw can adjust a tensile force of the tendon graft by adjusting the amount of screwing of the fixing screw into the bone plug after the head part of the fixing screw contacts the fixing member.

  • Patent number: 8137383
    Abstract: A method for securing first and second tissues with a suture anchor. The steps include forming a borehole in the first tissue; threading a suture through the second tissue forming a loop in the suture with the tissue thereby secured in the loop, the loop defining two suture portions; attaching the two suture portions to the anchor whereby the two suture portions are threaded through the anchor and initially movable with respect to the anchor; and providing a force to a shaft of the anchor, the force causing clamping of the two suture portions in the anchor and deformation of a deformable portion of the anchor to cause the deformable portion to engage a wall of the borehole thereby to secure the suture anchor in the first tissue and the loop holding the second tissue to the suture anchor.

  • Publication number: 20120065731
    Abstract: A line lock system may include a line routed through a plate. The plate may have an elongated body with a plurality of passageways. The line is routed to form at least one one-way slide so no knots are required. The system may include filaments routed through the passageways of the plate or around a dogbone feature of the plate. The filaments may be used to toggle the plate after passage through a hole to prevent withdrawal of the plate back through the hole. The system may include a line lock stabilizer or counter-tension tool to stabilize the line lock as the line is adjusted. The system may include a compression limiter to selectively reduce compression in the one-way slide to facilitate adjustment of the line. The line lock stabilizer, counter-tension tool, or compression limiter may be a filament.
