  • Tibial knee component with a mobile bearing
    Patent number: 6217618
    Abstract: An orthopaedic knee component for implanting within a proximal tibia includes a tibial tray with a distally extending stem, a proximal tibial plateau and a post extending from the tibial plateau. The post defines an axis of rotation. An intermediate carrier has an opening in which the post is disposed. The carrier is pivotal about the axis of rotation. A bearing carried by the tibial tray has an articular bearing surface for engagement with a femoral component. The bearing has a recess in which the intermediate carrier is disposed. The projection, carrier and recess allow pivotal movement of the bearing relative to the tibial plateau about the axis of rotation.
