Abstract

An orthopaedic implant assembly includes a plurality of commonly-sized dome patella components. Each of the commonly-sized dome patella components may be provided in various thicknesses and/or peak surface diameters.

Description

technical field [0001] The present disclosure relates generally to implantable orthopedic prostheses, and more particularly to implantable orthopedic prostheses having dome-shaped patella elements of the same size that vary in thickness and top surface diameter. Background technique [0002] During the patient's lifetime, the patient may require joint replacement surgery due to, for example, disease or trauma. Joint replacement surgery may involve the use of a prosthesis that is implanted in one or more of the patient's bones. In patella replacement surgery, an orthopedic prosthesis is implanted in the patient's patella. Specifically, the prosthetic patella component is secured to the patient's native patella such that its posterior surface articulates with the femoral component in extension and flexion of the knee. [0003] A conventional dome-shaped patella component embodies a dome-shaped polymer bearing with a spherical dome profile. Therefore, changing the thickness ...
