For the development of a Shape Memory Alloy (SMA) ligament prosthesis model, it is necessary to overcome the problem of the fatigue life under mechanical loading of nickel titanium wires. The degradation of the superelastic parameters as a function of the cyclic strain was evaluated and the number of cycles to failure under controled strain was established. On the basis of these results, an orientation in the design of the SMA ligament prosthesis can be proposed.
