A total knee prosthesis CAD design

摘要

The main topic treated in this paper is represented by the design of a total knee prosthesis in order to obtain a customized product for specific pathological cases (overweight, particular anatomical conformation for knee etc.). In such cases, given the complexity of geometric shape that has any tri-compartmental knee prosthesis and the particularity of individual dimensions of components, the final model obtained must be one close to reality, customized for each patient. Concepts of anatomy, physiology, biomechanics and surgery are very important when designing an implant such as that and shape should be as close to the portion that is intended to be replaced. The model must be built ergonomically so that the forces that appear in the knee during movement must be in normal parameters.
