  • Patent number: 8206446
    Abstract: An anterior cruciate ligament (ACL) surgical repair technique involves the use of a single femoral and tibial tunnel and an implant that separates and positions two distinct bundles. This allows for the surgeon to create a more anatomic reconstruction with a procedure that is less technically demanding, can be performed using a transtibial or anteromedial approach, minimizes tunnel widening, and decreases operative time. The result is a strong fixation option for soft tissue grafts, with circumferential graft compression at the aperture, high pull-out strength, and ease of use. The graft bundles are positioned in a more anatomic orientation through the above noted single femoral and tibial tunnel.

  • Patent number: 8192490
    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 reinforced graft construct for repairing a tendon or ligament formed by inserting a piece of material, such as suture, through the graft lengthwise. The material may be inserted along only a portion of the graft or along the entire graft. The material may be a reinforcement (reinforcing) material such as suture, tape, weave, or mesh passed lengthwise through the graft (for example, along the center of the graft). The ends of the graft may be whipstiched to provide additional fixation when implanted. The material may be bioabsorbable such that it will resorb away after a period of time in the body.

  • Patent number: 8118868
    Abstract: A system and method for attaching soft tissue to a prosthetic implant can include a prosthetic component that defines a soft tissue attachment region having an attachment surface thereon. A first construct can be formed of porous metal and be removably coupled to the attachment surface. A second construct can be positioned outboard of the soft tissue. A fastener can be engaged to the second construct capturing the soft tissue against the first construct. The fastener can be coupled on a distal end to the first prosthetic component.

  • Publication number: 20120016474
    Abstract: Methods for fixation of a soft tissue graft in a bone including: forming in the bone a tunnel defining an entrance opening and an exit opening at opposite ends of the tunnel, the tunnel including an anterior wall surface and a posterior wall surface opposite to the anterior wall surface; positioning the soft tissue graft within the tunnel such that the soft tissue graft extends through both the entrance opening and the exit opening of the tunnel; inserting a graft fixation apparatus into the tunnel and driving spikes of the graft fixation apparatus into the posterior wall surface to mount the graft fixation apparatus to the posterior wall surface of the tunnel such that the graft fixation apparatus is anterior to the posterior wall surface and is not recessed beneath the posterior wall surface; and securing the soft tissue graft inside the tunnel with the graft fixation apparatus.

  • Publication number: 20110319994
    Abstract: An interarticular ligament prosthesis is formed from a plurality of high strength high modulus polymeric fibers. The fibers are independent and free from intrinsic inter-fiber shear coupling found in braided or bonded fibers. The ligament prosthesis is installed with tubular, bone screw anchors. The fibers of the ligament prosthesis pass through the central hole of the anchors and are knotted at one end. The exit holes of the anchors include ceramic eyelets with polished edges. The edges are rounded to a defined radius for desired fatigue life of the prosthesis.
