Abstract
An orthopaedic knee component for implanting within a proximal tibia includes a tibial tray with a proximal tibial plateau and a distally extending stem. The tibial tray also includes a recess extending into the tibial plateau. The recess is configured to define a first rotational stop and a second rotational stop. The tibial tray further includes a generally cylindrical post positioned within the recess. The post extends generally orthogonal to the tibial plateau and defines an axis of rotation. A bearing is carried by the tibial tray and has an articular bearing surface for engagement with a femoral component. The bearing has an opening in which the post is disposed. The opening and the post allow pivotal movement of the bearing relative to the tibial plateau about the axis of rotation. The bearing further has a projection extending into the recess of the tibial tray. The projection is configured to abut the first rotational stop when the bearing is at a first rotational limit and is configured to abut the second rotational stop when the bearing is at a second rotational limit.
