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.

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.

Endosteal fixation of a ligament graft with a bioabsorbable interference screw installed in a retrograde manner in ACL reconstruction. The bioabsorbable interference screw is insert-molded with a length of suture extending from the distal tip of the screw for pulling the interference screw into the joint and into position for retrograde insertion at the top of the tibial tunnel. The interference screw has a cannulation extending partially through the screw from the leading tip. The cannulation is shaped to receive a correspondingly shaped driver. The driver is inserted into the tibial tunnel to engage the screw. By turning the driver, the interference screw is turned into the tibial tunnel in a retrograde manner. Accordingly, interference fixation of the graft near the tibial plateau is provided, thereby eliminating graft abrasion at the tibial plateau tunnel opening.

Apparatus for autogenous or allograft transplantation of articular cartilage with bone from one site, such as in the knee, to another to treat chondral defects. Graft harvesters and recipient site harvesters create identically-sized donor graft osteochondral cores and recipient sockets. Collared pins disposed within the harvesters facilitate removal of the harvested cores. Windows formed in the side of the harvester tubes allow visualization of the graft, such as when being inserted into the recipient socket. A removable three-piece driver/extractor is provided to allow for impact-driving and depth control of the harvesters at the selected sites.

Method and apparatus for osteochondral autograft transplantation

A method of reconstructing the anterior cruciate ligament using arthroscopic surgery. A closed-ended socket is formed in the tibia and the femur. The locations of the sockets are determined using an offset aimer to reference anatomical structures within the knee. An ACL graft is fixated in the tibial and femoral sockets using interference screws. The method obviates the need to form tibial incisions and tunnels, as required by existing methods.

A drill guide for marking a proper location of a bone tunnel for arthroseopic surgery, provided with a marking hook designed to reference the posterior cruciate ligament. The marking hook includes a slot to allow the surgeon to view endoscopically the position of a guide pin as it is drilled through the tibia.

A tibial tunnel guide which enables accurate tibial tunnel placement both inside and outside the knee for use in endoscopic ACL reconstruction. The guide utilizes a consistency between the PCL and the ACL anatomic structure to accurately locate the ideal position of the tibial tunnel. The guide includes an arc shaped outrigger with a slot along its length, a sighting device secured to the outrigger in the slot and adapted to receive a guide pin, and a grasping tool adjustably secured to the outrigger in the slot having a grasper at one end. The grasper is arranged to grasp the base of the PCL near the intercondylar floor from the anteromedial portal. The sighting device is fixed relative to the position of the crotch of the grasper and locates the guide pin at an ideal position for tibial tunnel placement.

PCL oriented placement tibial guide

A method for preparing a bone-tendon-bone core graft. A bone core is harvested from a patient and divided into two separate bone core halves. The bone core halves are inserted onto holding pins which are movably spaced along a work station. A harvested tendon is secured with suture onto the bone core halves, with the tendon extending therebetween to form the bone-tendon-bone core graft. The holding pins are supported by blocks which are moved apart along the work station to tension the bone-tendon-bone graft.

PCL oriented placement tibial guide method

A bone drill bit for drilling a hole through bone, cartilage and/or other soft tissue, and the like includes an elongate cylindrical shaft having a pointed tip at one end and a shank at the other end which is adapted to be received in a surgical drilling apparatus. A plurality of small protuberances are provided around the cylindrical shaft adjacent the tip so that as the protuberances pass through the drilled bone a hole slightly larger than the shank is produced and thus the shank passes freely through the drilled hole. Preferably, the protuberances are diamond shaped and the pointed tip is pyramidal shaped. In addition, a suture holding device, such as an aperture or hook at the end of the shank, is provided for holding a suture to the shank as the shank passes through the drilled hole. A portion of the shank is cut away on either side of the suture holding device to provide clearance for the suture. Where the suture holding device is an aperture, this aperture is preferably countersunk at both ends.
