    Abstract: A knee prosthesis and a method of selecting for a particular patient a knee prosthesis from an inventory of available knee prostheses or from 3D knee prosthesis models is provided. The method includes the steps of (a) parameterizing a knee prosthesis according to well-defined and independent knee joint compartments, (b) generating a large number knee shapes in the form of 3D knee prosthesis models which reproduce the 3D shape asymmetries of each individual knee, thereby enabling the replication of the knee motion of essentially any patient by generating shapes which vary the shape parameters (surface and dimension) of at least one of those compartments and storing these 3D knee prosthesis models in a database, and (c) studying the patient's pathology and developing pre -pathological knee prosthesis criteria matching the patient's needs. Using a planning algorithm, a suitable knee prosthesis may be selected among an inventory of existing knee prostheses or the large number of knee shapes, the prosthesis or shape selected best meeting the patient's needs as determined by the study.
