Abstract
An implantable patellar prosthesis accommodates variations in placement of the prosthesis relative to the patella without limiting use of the prosthesis. The prosthesis utilizes a base component having a fixation portion for fixation to patellar bone. Additionally, the device uses an articulation component that may move relative to the base component. A coupling mechanism is provided for coupling the articulation component to the base component while permitting relative motion of the articulation component with respect to the base component. This relative motion can be controlled according to the design of the prosthesis and facilitates implantation as well as use of the prosthesis.
