Abstract

Introduction: It has been shown that walking kinematics remain near to normal after mobile bearing total ankle replacement (TAR). However, no information is available on mechanical joint loading. The purpose of this study was to determine whether mechanical load and 'quasi-stiffness' of the ankle joint after TAR differs from the normal load and stiffness of a healthy ankle joint during walking. Methods: Ten TAR patients and 10 age-matched healthy control subjects (CO) participated in this study. Participants walked barefooted on an indoor track at self-selected walking speed. 3D ankle kinematics and ground reaction force were measured and used for the calculation of 3D net joint moments, joint quasi-stiffness coefficients and internal net joint ankle work. Results: Between patients and control subjects no differences were observed in peak moments and stiffness coefficient at the ankle. Internal work at the ankle during the step differed however, significantly (-0.078 (0.088) J kg
