Mechanical Analysis of Scandinavian Total Ankle Replacement Prostheses Through Finite Element

The paper presents the results of the processing of information obtained by studying the Scandinavian Total Ankle Prosthesis (S.T.A.R.) second generation and third generation. Knowing the geometric and mechanical characteristics, evaluating the nodal forces (forces and couples) caused by the distributed loads along the endoprostheses, this study was realized considering that a finite element model of the ankle joint could be useful to provide a perspective on the mechanisms the effects of treatment, and the role of mechanical factors in degenerative conditions. Preparing such a model involved many geometric simplifications and the introduction of material properties.
