Lower limb prostheses are advanced medical devices designed to replace missing or amputated limbs below the knee or above the knee. These prostheses are custom-made to fit each individual's unique anatomy and provide support, mobility, and improved quality of life. They are typically composed of a socket, which connects to the residual limb, a pylon or rod that acts as a support structure, and a foot or ankle component that mimics the functionality of a natural limb. Modern lower limb prostheses employ cutting-edge materials, such as carbon fiber composites, which offer strength, durability, and flexibility, enabling users to perform a wide range of activities, from walking and running to engaging in sports and recreational pursuits.
