    Abstract

    The tribological problems in a knee joint have been discussed. The items examined include the incongruent joint structure, cartilage tissue and its lubrication, kinematics and loading. The reasons why the reciprocating pin-on-flat set-up included in the ASTM F732-82 (Reapproved 1991) standard is not satisfactory for the ranking of candidate materials for joint replacement prostheses are discussed. A set-up incorporating both the sliding and rolling motions is suggested as a better system.
