The Basic Requirements and Design Criteria for Total Joint Prostheses

Abstract

In the past some joint prostheses have been used in which the fundamental requirements of joint replacement were not fully considered. This paper lists the basic requirements for joint replacement and thirteen criteria which should be employed in designing a prosthesis to meet these requirements. The criteria are discussed in detail. The requirements and criteria are important but, because some may conflict with others, joint design is often a compromise.
