Lower extremity prosthesis come in many different forms and types. Above-the-knee prosthesis are made for amputations that are at or above the knee joint. The prosthetic is designed to replicate a human knee, thigh, ankle, and foot.
While below-the-knee-prosthesis are designed to support amputations that are performed between the ankle and knee. These prosthetics are also designed with moveable and adjustable joints and pylons so they can replicate the movement of a human thigh, ankle, and foot. Similar to above-the-knee-prosthesis.
