碩士 === 元智大學 === 機械工程研究所 === 89 === This is an interdisciplinary research project in which surgeons and engineers investigate together the design of a total knee prostheses from various view points, including anatomy, biomechanics, kinematics, mechanical design, material. The purpose of this project is to design a reliable and robust total knee prostheses whose motion pattern is close to real knee. The characteristic of the new total knee prosthesis is the shape of meniscus was be designed to protrude, it can eliminate particle that was been ground. The contact face of femur and meniscus was designed to dual inclusive line, it can make maximum contact face, reduce contact stress, when human standing or in the flexion and extension period. The new total knee prosthesis can flexion and extension to 150 degrees, when it flexion to 150 degrees, the anterior direction displacement of femur center is 8.98mm, the amount of axis rotation is 15.16 degrees, the A-P displacement is 4.05mm, and the sidelong slides is 4mm. Due to the guide surface, the new total knee prosthesis have good stability when it produce relative motion.
