摘要：
A system of prosthetic patellar components including first and second prosthetic patellar components having dissimilar perimeter shapes and which are interchangeably useable without altering the securement feature formed on the natural patella or the position of the apex of the articulating surface of the prosthetic patella is described. A keyed securement feature as well as a patellar implant having a single offset mounting post for facilitating the proper placement of a patellar prosthesis on a natural patella based on patella tracking are also described.
