Abstract

This study describes the development of a novel, patient-specific unicompartmental knee prosthesis. The geometries of the lateral and medial condyles are approximated by polynomials, instead of single radius circles that are commonly used. Furthermore, a database containing the geometries of healthy knees is used to generate appropriate knee geometries according to certain measurements of the unhealthy knee. This new method enables a customized design of a unicompartmental knee replacement that will closely resemble the articulating surfaces of the normal, healthy knee joint.
