    Abstract: A system and method for securing an ACL graftmay include a line routed through a plate. The plate may include an elongated body with a plurality of passageways, and a dogbone feature on at least one end of the body. The line may be routed to create at least one one-way slide so no knots are required. The line may form an adjustable loop that receives the graft. The adjustable loop is adjustable through the one-way slide feature. The plate may be configured to pass through a bone tunnel. The plate may be toggled after passage through the bone tunnel to prevent withdrawal back through the bone tunnel because the plate contact area is larger the bone tunnel area.

The system is easy to use, requires no additional accessories, uses only a single drill hole, and can be implanted by one person. Additionally, it replicates the native ACL by compressing the tendons against the aperture of the tibial tunnel, which leads to a shorter graft and increased graft stiffness. It is adapted to accommodate single or double tendon bundle autografts or allografts. It also provides pull out strength measured to be greater than 1000 N.

    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.

    Abstract: A system and method for securing an ACL graft. The system may comprise a line routed through a plate, the plate may comprise an elongated body with a plurality of passageways, and a dogbone feature on one end. The line is routed such to create at least one one-way slide so no knots are required. The line may comprise an adjustable loop that receives the graft. The adjustable loop is adjustable through the one-way slide feature of the line routed around and through the plate. The plate may be configured to pass through a bone tunnel with the use of filaments routed through the passageways of the plate or around the dogbone feature of the plate. The filaments may be used to toggle the plate after passage through the bone tunnel to prevent withdrawal back through the bone tunnel because the plate contact area is larger the bone tunnel area.

  • Patent number: 7967861
    Abstract: A material fixation system is particularly adapted to improve the tendon-to-bone fixation of hamstring autografts, as well as other soft tissue ACL reconstruction techniques. The system is easy to use, requires no additional accessories, uses only a single drill hole, and can be implanted by one person. Additionally, it replicates the native ACL by compressing the tendons against the aperture of the tibial tunnel, which leads to a shorter graft and increased graft stiffness. It is adapted to accommodate single or double tendon bundle autografts or allografts. It also provides pull out strength measured to be greater than 1000 N.

  • Publication number: 20110153018
    Abstract: An apparatus and method for performing a surgery, especially an ACL replacement surgery, where a flexible strand insertion rod co-operates with a U-Guide apparatus to insert a flexible strand into a tunnel formed in a bone portion and to guide a pair of drill points to form a pair of tunnels transversely to the tunnel of the insertion rod. The drill points are guided through the insertion rod and the flexible strand is held over the drill points as the transverse tunnels are formed. The insertion rod is then removed from the tunnels formed in the bone and the flexible strand is held looped over the second drill point. Subsequently, a soft tissue replacement is affixed to one end of the flexible strand and pulled over up to the first drill point with the other end of the flexible strand. The first drill point is then used to pull a cross pin through the transverse tunnel to hold the looped end of the soft tissue replacement in place.

  • Patent number: 7963984
    Abstract: A novel fixation system for fixing a graft ligament in a bone tunnel. The fixation system comprises an interference screw comprising a body having a distal end and a proximal end, screw threads extending longitudinally along the body, and a transversely-extending region formed in the body for receiving a transverse pin therein, whereby to securely lock the interference screw, and hence the graft ligament, to the bone. In accordance with a further feature of the present invention, there is provided a method for attaching a graft ligament to a bone, the method comprising the steps of: (i) drilling a tunnel in the bone; (ii) positioning the graft ligament in the bone tunnel; (iii) placing an interference screw in the bone tunnel so as to force the graft ligament laterally against the opposite side of the bone tunnel; and (iv) advancing a transverse pin transversely through the bone and through the interference screw so as to securely lock the interference screw, and hence the graft ligament, to the bone.

  • Publication number: 20110137416
    Abstract: A system for single tunnel, double bundle anterior cruciate ligament reconstruction includes implant constructs and instruments. The implant constructs provide a combination of cortical fixation and bone tunnel aperture fixation. The implant constructs separate a graft into distinct bundles. The instruments are used to prepare shaped bone tunnels to receive the implant constructs and graft bundles. Methods for reconstructing the antero-medial and postero-lateral bundles of the anterior cruciate ligament may rely on single femoral and tibial tunnels and a single strand of graft.

  • Publication number: 20110118838
    Abstract: A placement assembly used for positioning and holding a ligament graft within a selected bone tunnel. The assembly includes a graft pulley, a surgical suture, and a graft pulley placement instrument. The graft pulley includes a pulley portion and a bone anchoring portion. The pulley portion is adapted to receive the surgical suture and for surgical suture to be drawn through it, to act as a pulley. The bone anchoring portion comprises a portion adapted to selectively fix the graft pulley within a bone tunnel. The graft instrument may be selectively attached to the graft pulley and includes a handle and elongate body, adapted to insert the graft pulley into the selected bone tunnel. Once the graft pulley is in place, the placement instrument may then be detached and withdrawn leaving the graft pulley firmly fixed within the bone tunnel and can then be used to position a ligament graft.

  • Patent number: RE42526
    Abstract: A method of securing a graft in a bone tunnel, in which graft is secured within the tunnel at both the entrance and the exit ends of the tunnel to provide bicortical fixation of the graft in the bone. Interference screws or other fixation devices are used to secure the graft within the tunnel. For tibial tunnel fixation using an interference screw, the back end of the distal screw is angled so that it closely approximates the angle of the outer tibial tunnel rim. The distal screw is non-cannulated to prevent hematomas from being formed by blood flowing from the tibial tunnel into the surrounding soft tissue. The proximal screw has a restricted cannula to minimize the flow of synovial fluid entering the tibial tunnel. Advantageously, the space between the two screws fills with blood to promote faster healing and incorporation of the graft in the tibial tunnel.
