Abstract
An orthopaedic knee component for implanting within a proximal tibia includes a tibial tray having a distally extending stem, a proximal tibial plateau and an annular shaped recess extending into the tibial plateau. The recess has a substantially constant radius of curvature about an axis of rotation. A bearing carried by the tibial tray has an articular bearing surface for engagement with a femoral component. The bearing has an annular shaped projection extending into the recess. The projection and the recess allow pivotal movement of the bearing relative to the tibial plateau about the axis of rotation.
