    摘要： An orthopedic knee component for implanting within a single compartment of a human knee includes, in a first embodiment a tibial tray having a superior surface having a plurality of tabs disposed along an exterior edge thereof, a bearing component having a superior surface adapted to articularly engage a femoral knee prosthesis and a circumferential groove disposed therearound with which the tabs of the tibial tray cooperatively engage such that the bearing component is movable relative to the tibial tray. In a second embodiment, an orthopedic knee component for implanting within a single compartment of a human knee includes: a tibial tray in supporting engagement with a bearing component, wherein the bearing component includes a superior surface adapted to articularly engage a femoral knee prosthesis and a pair of slots disposed along the superior surface of the bearing component, the femoral component having a pair of rails extending from the articulating surface thereof such that the rails can slidingly engage the slots, and such that the bearing component is movable relative to the tibial tray.

    摘要： A constrained prosthetic knee having a modular hinge post and a rotating bearing. A cannulated hinge post is rotatably connected to the femoral component of the knee prosthesis so that a hinge post extension may be anteriorly positioned through the hinge post and into the tibial component of the knee prosthesis, after positioning of the femoral component in the femur and the tibial component in the tibia. The hinge post is preassembled to the femoral component so that such assembly is not required during the implantation procedure. A meniscal component forming the rotating bearing of the knee prosthesis is packaged together with the hinge post extension so that the appropriate hinge post extension is readily available. The meniscal component includes a mechanism for preventing lift off of the meniscal component from the tibial component, while allowing rotation of the meniscal component relative to the tibial component.

    摘要： A mobile bearing unicondylar tibial knee prosthesis includes a tibial base plate and a tibial articular surface component. The inferior surface of the articular surface component engages the superior surface of the base plate in sliding relationship. The tibial articular surface and a stop on the tibial base plate define a tab and groove engagement between them such that the tibial articular surface component is permitted to slide anteriorly-posteriorly on the tibial base plate while movement of the tibial articular surface component superiorly away from the base plate is restricted.
