Summary

Transtibial amputation accounts for 3,700 cases per year in France. Athletes can use sport blades made of carbon plate for improved energy restitution. Sports blades are adjusted according to the manufacturer's recommendations and the subjective experience of the ortho-prosthetist and patient. These adjustments are designed to optimize performance and comfort while reducing the risk of injury. This risk is all the greater when asymmetries between the healthy and affected limbs are large, exposing the healthy limb to large and repeated reaction forces.
