Below-the-knee prosthesis

Abstract

A hollow, rigid, lightweight nonarticulated prosthesis with a foreshortened foot fits the stump of a below-the-knee amputee and has an optional simple above the knee-cap holding strap to secure the prosthesis when the knee is straightened. The center of mass of the prosthesis is much closer to the knee than is the center of mass of a natural leg.
