摘要:
An orthopaedic joint prosthesis may include a first component, a bearing component, and a third component. The first component has a base and a keel protruding from the base to extend into a first bone. The keels longitudinal axis is offset from a geometric center of the base. The base has a first articular surface and the bearing component has a second articular surface shaped to articulate with the first articular surface. A feature unitary with the first component reversibly attaches to the bearing component. The bearing component has a third articular surface shaped to articulate with a fourth articular surface on the third component. A distraction feature of the bearing component is shaped to provide alignment and/or distraction between the first articular surface and the fourth articular surface during insertion of the bearing component into a joint space between the first and second bones.
