Total Ankle Replacement (TAR) has been shown to lack the long term reliability of other implants. Many efforts have been made to improve the design. These have included simply exploiting more anatomically shaped prosthesis; however understanding the fundamental mechanics of the joint based upon robust experimental data is perhaps a more promising approach. Current data describing ankle joint forces have been calculated based on questionable assumptions from a very limited number of investigations dating back to the 1970s. The purpose of this study is to develop a more sophisticated computer simulation of the ankle joint to provide more reliable data than currently exist.
