    Abstract: A joint replacement component comprising a metal tray (3) and polymer liner (27). The metal tray having screw holes (7a, 7b) for fixation with screws (9) to bone, and a circumferential rim or wall (15) with a smooth inner surface (21). The liner having a flexible sealing ridge (39) around its entire periphery for tray engagement, forming a fluid-tight seal between the liner and tray. The liner having a locking mechanism comprised of tabs (35) at longitudinal ends of the liner, which engage grooves (23) in the tray's front and rear. Following tray fixation to the resected skeletal structure, a surgeon installs the liner within the tray by angling the liner, inserting first tab into its respective groove, pressing the liner downwardly into the tray causing the liners opposing tab to engage its respective groove, snap-locking the liner within the tray, and simultaneously sealing the liner to the tray by the flexible sealing ridge.

    Abstract: Implant with multi-directional pivoting has a first component including a first articular surface and a fore-to-aft and side-to-side rotation device; and a second component including a second articular surface for mating with the first surface and a rotation device receptacle. The first component can be mated to the second through cooperation of the rotation device and receptacle, and the first component can cooperate with the second in articular surface contact. The joint may be a knee prosthesis comprising first femoral and second tibial components, with the first surface a femoral condylar surface and the second surface a tibial condylar surface. Therein, the fore-to-aft component can be considered flexion, with the side-to-side component considered version. A knee prosthesis can also be provided with a patella support on a smooth counter surface from full extension to flexion well past 100 degrees and/or with a mechanism preventing excessive downward tibial component travel.

    Abstract: TIBIAL SURFACE SHAPING GUIDE FOR KNEE IMPLANTS The present invention provides a shaping guide to permit accurate shaping of the tibial plateau while saving the anterior cruciate ligament. An alignment rod is located anterior to the anterior cruciate ligament and along the anterior cortex of the intermedullary canal of the tibia provides points of reference for all shaping operations. The shaping guide of the present invention is adiustable with respect to the handle portion of the rod so that the amount of resection of the tibial plateau can be controlled readily by the surgeon by raising or lowering of the cutting guide surfaces for resection of the tibia.

    Abstract: Apparatus and method for determining the kinematics of a large joint (e.g., a knee) undergoing arthroplasty, for comparing the kinematics of the joint undergoing surgery with the kinematics of the normal joint, and for providing the surgeon with information allowing the balancing of the ligaments of the joint upon the installation of a prosthesis replacement joint. The apparatus includes optical targets mounted on joint replacement components fitted to the resected bones of the joint. One or more video cameras are used to obtain a series of images of the various optical targets as the extremity is flexed, extended, and rotated. A computer is responsive to the images of the targets to determine the kinematics of the joint as it is flexed, extended and rotated. The computer compares the kinematics of the observed joint with the kinematics of a normal joint and determines, based on anomalies of the observed joint relative to the normal joint, whether other implant components or spacers are required, and determines which ligaments must be relaxed or contracted so that the ligaments are balanced. The computer displays suggestions to the surgeon for changing components and for relaxing or contracting specific ligaments such that the ligaments of the joint is balanced with the prosthesis joint in place. A method of computer ligament balancing is also disclosed.
