  • Patent number: 9326844
    Abstract: Techniques and reconstruction systems for fixation of bone to bone, or soft tissue to bone, that allow a double-bundle type construct with only three tunnels, a single graft and individual tensioning in each of the three tunnels. Alternative double-bundle ACL/PCL fixation techniques are provided that employ a double-bundle type construct with only a single graft and three tunnels/sockets. The double-bundle ACL and PCL techniques and constructs allow individual tensioning of each of the bundles (e.g., tensioning of each of the anteromedial (AM) and posterolateral (PL) bundles of the ACL) and eliminate the need for additional fixation devices (for example, interference screws) to secure the bundles within the bone tunnels/sockets.

  • Patent number: 9226815
    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.

  • Publication number: 20150313586
    Abstract: A swivel suture anchor for knotless fixation of tissue. The suture anchor includes an anchor tip configured to capture suture, the anchor tip being rotatably received within a fixation device upon advancement of the fixation device over a shaft of the anchor tip. The anchor tip is configured to receive a suture to be anchor in bone without requiring suture knots. The anchor tip can be a conical metal tip which is self-punching and avoids the need for pre-drilling a hole in bone. The anchor tip includes a closed aperture to allow free sliding of a suture strand. The suture is secured in a hole in bone by inserting the anchor tip into bone, and advancing a fenestrated fixation device, such as a cannulated interference screw, over a shaft of the anchor tip.

  • Patent number: 9146576
    Abstract: A rotation mechanism (rotating device) that can be easily accessed by the surgeon's finger to rotate an endoscope or similar instrument. The rotation mechanism is a device/component with a “starfish” configuration, which can be attached to the endoscope/arthroscope just distal to the eyepiece (or to an alternate attachment to a camera). The starfish component has a plurality of projections that extend radially from the endoscope axis, and beyond the diameter of the mechanism on the camera head that grasps the arthroscope eyecup. The projections can be easily accessed by the surgeon's finger to rotate the endoscope.

  • Patent number: 8939980
    Abstract: A system for anterior cruciate ligament (ACL) reconstruction using holes in bone created by retrograde cutting. A rotary cutter, mounted onto an insertion post of a tibial guide, is inserted through an anteromedial portal and the rotary cutter placed on the anatomical origin of an ACL tibial insertion. A drill pin is drilled through the tibia and advanced until it contacts and engages a cannulation in the rotary cutter on the guide. Further rotation of the drill pin disengages the rotary cutter from the guide. The retrograde drill pin is then retracted and simultaneously rotated for retrograde cutting of a socket or tunnel of desired depth in the tibia. A similar system is provided to form a socket or tunnel in the femur except that a femur guide is used in place of the tibial guide.
