Development Of A Muscle Actuator System

Abstract

Pre-clinical testing methods of total knee replacement (TKR) implants use different simulator platforms for characterizing the anticipated biomechanics of a reconstructed joint. Each system manipulates the joint using a different type of control. Musclecontrolled simulators apply forces to the quadriceps to generate motion, whereas force-and displacement-controlled simulators directly manipulate bone. Simulator costs limit testing to a single platform at a time. Limitations of each system prevents a full understanding of factors contributing to joint instability after TKR surgery. The aim of this study is to develop a joint motion simulator capable of muscle, force, and displacement-controlled loading.
