Abstract: An arthroscopic tibial sizer provided with a collapsible loop (for example, a nitinol loop) and a pin indicator located at about the center of the collapsible loop. The collapsible loop is formed of a flexible wire (for example, nitinol wire) and is designed to collapse so that it can be inserted through an arthroscopic portal and into the joint, and then to expand out to its original diameter once inside the joint space, for visual sizing. The collapsible loop may be provided in various diameters (i.e., 14, 17 or 20 mm, for example) to match various implant sizes. The pin indicator indicates the center of the loop and provides identification of the center of the tibial defect.

Abstract: A three-dimensional mesh or screen in the shape of a simple flat piece of material that can be provided adjacent the graft (i.e., in between graft bundles, or around the graft, or between the graft and the fixation device) for improved strength and structural support for graft fixation. The mesh provides improved methods for installing and securing ligament grafts (such as double-bundle cruciate ligament grafts) with enhanced reconstruction results.

Abstract: A continuous loop and button construct and technique for ligament repair and fixation, including bone to bone, or soft tissue to bone. The continuous loop, which is attached to the button, is formed of a flexible material and is provided with at least one joined region (a bridged, stitched, bonded or knotted region) to form a closed loop figure-8 construct with proximal and distal openings with respect to the fixation device. The figure-8 construct (either bridged, stitched, bonded or knotted) is adapted for attachment to a bone block of a BTB graft, for example, and used for ligament reconstruction.

Abstract: An adjustable construct for fixation of a tendon or ligament graft in a tunnel. The construct comprises a flexible, adjustable loop connected to tissue (for example, graft, ligament or tendon). The adjustable loop may be integrated with an additional tissue supporting device (for example, a wedge or a plug). The tissue is secured within a bone socket/tunnel by adjusting the length of the flexible adjustable loop.

Abstract: An adjustable button/loop device for securing biologic material in bone, such as for ACL reconstruction. The device has a pair of button/loop constructs, each including a flexible, adjustable loop integrated with a fixation device (for example, a wedge). Biologic material (for example, soft tissue, graft, ligament or tendon) is secured to the two fixation devices, and the construct is inserted into a pair of bone sockets/tunnels, such as into a tunnel in the tibia and a socket in the femur. The biologic material is secured within the bone by passing the buttons though respective bone sockets/tunnels, flipping and seating the buttons outside the bone, and then adjusting the lengths of the flexible adjustable loops passing through the buttons and the respective fixation devices, with the graft extending between the fixation devices thereby appropriately secured in the bone.

Abstract: A technique for forming a dovetail shaped groove in bone necessary in allograft transplantation such as the meniscus or the Achilles tendon. The technique uses a single drill guide that is designed to create a dovetail shape in bone. The drill guide is provided with a first opening for receiving one drill sleeve placed in a fixed location, and a second opening having an oblong shape for receiving a second drill sleeve having an offset cannulation. The combination of the two drill sleeves allows the surgeon to place two guide pins and ream over each guide pin resulting in a dovetail shape in the bone.

Abstract: A flip retrograde cutting instrument and method of retrograde drilling using such an instrument. A method of forming a socket includes providing a flip retrograde cutter, inserting the cutter into a joint with a blade of the cutter in a straight position, pivoting the blade to a non-straight flip position, locking the blade in the flip position, and retrograde drilling a socket using the blade in the flip position.

Abstract: Systems and methods for repairing tears in soft tissue, e.g., meniscal tissue, by employing cinch stitching. More specifically, the present invention provides apparatus and methods for meniscal repair using a suture implant construct. The suture implant construct includes a first and second implant which are connected to each other via a length of suture. The implants are designed to be loaded on external surfaces of the first and second trocars.

Abstract: Measuring devices and methods of determining the appropriate graft length for reconstructive surgery, for example for an all-inside ACL reconstruction ligament repair. The measuring device accurately determines the graft length based on the total length between the femoral and tibial tunnels (sockets) plus the intraarticular space between them. The measuring device may comprise two small, cannulated beads (preferably polished metal) and three strands (for example, three suture strands). The beads may have a diameter of about 5 mm and the three sutures may preferably have distinct and different colors.

Abstract: A method and apparatus for arthroscopic unicompartmental knee surgery which include a femoral component and a tibial component. The femoral component is installed in a trough in the femoral condyle formed by using a template, a plurality of drill pins and a plurality of corresponding cutters. The template is aligned with the curvature of the femoral condyle, the two drill pins are passed through the template and drilled into the femur, cutters are advanced over the corresponding drill pins to make holes in the femur, and the remaining hourglass shaped bone is removed with osteotomy pliers to form the trough. A tibial socket for the tibial component is formed in a retrograde manner.

Abstract: A device for tensioning suture which includes a cannulated tube that allows a suture to be fed through at least a portion of the tube. An adjustment device (for example, a wheel or a knob) is actuated to turn a threaded post on the end of the tube. A length of suture passes through at least a portion of the cannulated tube and is secured into a forked pin attached to the adjustment device. Turning the adjustment device draws against the suture, increasing therefore the tension on the suture. The suture tensioning device may be employed in conjunction with a tensiometer.

Abstract: A technique and reconstruction system for ligament repair by determining the exact length of the graft to be secured within a first tunnel or socket (for example, a tibial tunnel) and a second tunnel or socket (for example, a femoral tunnel) for improved graft fixation. The exact length of the graft (soft tissue graft or BTB graft, for example) is determined with a measuring device, by measuring the length of a first socket in a first bone region (for example, a tibial socket), the length of a second socket in a second bone region (for example, a femoral socket), and the length of the intraarticular joint space between the two sockets in the two bone regions (for example, tibia and femur). The measuring device may consist of at least one flexible member (for example, suture) with at least one fixation device attached to the flexible member, the fixation device being either a sliding knot, a washer or a button.

Abstract: A technique and reconstruction system for ligament repair employing a continuous loop/button construct. The button has an oblong configuration and is provided with at least one inside eyelet that allows the passage of the continuous loop, preferably a suture loop. The continuous loop/button construct of the present invention may be used for fixation of bone to bone, or of soft tissue to bone.

Abstract: A two sided cylindrical chondral resurfacing implant that covers areas of the highest contact between the tibia and femur. A dual-sided rotary drill cutter is employed to create a tibial socket from outside in. A full femoral trough is made with the opposite side of the rotary drill cutter by simply moving the knee through flexion and extension. In this manner, automatic alignment of femoral and tibial components is achieved due to the “transtibial” nature of the femoral preparation.

Abstract: A compression staple that can secure tissue (for example, bone) easily and effectively, and can provide improved fixation capabilities. The compression staple comprises a yolk or central portion having an S-shaped profile and two posts located at the bottom surface of the central portion. The two posts have a cylindrical configuration and may be cannulated. The posts may be also provided with a plurality of ribbed barbs, preferably extending about one third the length of the posts. The compression staple may additionally comprise two spikes located at the bottom surface of the central portion. The spikes are configured to increase fixation of the staple into the bone and to allow easy penetration through the cortical bone into the cancellous bone.

Abstract: An implant is provided for replacing the articular portion of a bone. The implant includes spaces adjacent bones in articulating relation and threadably anchors the implant to a bone. The threaded anchor permits bone growth axially and transversely therethrough.

Abstract: An improved constrained socket for use with an orthopedic implant for replacing a ball-and-socket joint. The constrained socket includes cuts extending from the opening of the socket generally toward the articular region thereof. Petals are formed between adjacent cuts in the socket. The socket further includes an annular expansion cutout, with the aforementioned cuts terminating therein. The socket does not include cuts on the primary articular surface, but nevertheless has a relatively low assembly force to allow assembly of the ball-and-socket joint during a surgical procedure. The relatively low assembly force of the constrained socket of the current disclosure is due in part to the annular expansion cutout which allows sufficient outward flexure of the petals to allow insertion of the ball of the ball-and-socket joint.
