Claim Text:
1. A tibial prosthesis system for implantation on a resected surface of a proximal tibia, the tibial prosthesis system comprising: a bearing component having a superior articulating surface and an inferior surface; a base component having a superior surface and an inferior surface, the superior surface having a feature configured to mate with a corresponding second feature on the inferior surface of the bearing component, the feature and the second feature configured to allow the bearing component to be movable relative to the base component in a proximal/distal direction and the feature and the second feature configured to prevent significant relative movement between the bearing component and the base component in a medial/lateral direction and an anterior/posterior direction; a shim component configured to be removably received between the inferior surface of the bearing component and the superior surface of the base component by insertion of the shim component therebetween, the insertion of the shim component changes a relative proximal/distal position between the inferior surface of the bearing component and the superior surface of the base component; and a tibial baseplate having a bone contacting surface adapted to interface with the resected surface of the proximal tibia and an opposing baseplate superior surface, wherein the base component is configured to be coupled to the tibial baseplate.
