ABSTRACT:
This patellar tendon bearing (PTB) prosthesis has a socket, a modular shank component, and a foot component which is attached rotatably to the shank component.
It allows a more comfortable sitting of the amputee fitted with such a prosthesis by allowing the foot component of the prosthesis to be safely and smoothly axially rotated inwardly or outwardly (.+-.90.degree.) with respect to the shank component of the prosthesis and to distribute uniformly the load, while sitting, on the whole lower limb, and to be latched in one of several positions.
