This research addresses a human ankle joint prosthesis design based on a cam mechanism. Thus, a dynamic analysis of the entire human lower limb was performed in order to obtain the input data for numerical simulations of an ankle joint prosthesis. For this, experimental analysis was accomplished in order to obtain input and reference data for human ankle joint motion laws. These human ankle joint motion laws were considered from a healthy human subject and an amputee. A virtual model of the ankle joint prosthesis was designed with the aid of CATIA software and the working principle was based on a cam mechanism. This virtual model was simulated in dynamic conditions, similar to the imposed ones onto a mathematical model. Results represented through stress and deformations will validate the proposed ankle prosthesis prototype. Finally the proposed prosthesis prototype was manufactured and experimentally tested on the proposed amputee through a comparative analysis for validation.
