The document describes the design of a prosthetic leg, including its foot and knee components. The foot is designed using generative design and joins the leg to the foot, allowing up to 14 degrees of ankle flexion. It contains a spring and damper to store energy and absorb shock during heel strike, as well as an inclination for toe off. The knee connects to the residual limb socket and contains a pneumatic device and mechanical locking to facilitate up to 135 degrees of flexion and lock the knee at required angles.
