Prosthetic device

A prosthetic device for a lower extremity, the prosthetic device comprising:

• a prosthetic knee joint having an upper part on which a proximal prosthetic component is arranged;
• a lower part which is connected to the upper part so to be pivotable about a knee joint axis;
• and
• a distal prosthetic component formed telescopically on the lower part or mounted displaceably on the lower part, on which a prosthetic foot is formed or can be secured;
• wherein the distal prosthetic component is mounted so as to be linearly and longitudinally displaceable in the direction of the knee joint axis by means of an axial force acting in the longitudinal extent of the distal prosthetic component, and wherein the knee joint is assigned a force transmission device in the form of a mechanical or hydraulic force transmission device which, in the stance phase, converts the linear and longitudinal displacement of the distal prosthetic component in the direction of the knee joint axis into a flexion moment about the knee joint axis.

• and
• an energy storage device assigned to the knee joint for storing flexion energy;
• wherein the distal prosthetic component is mounted via a spring element so as to be prestressed against a displacement, and so as to be linearly and longitudinally displaceable in the direction of the knee joint axis by means of an axial force acting in the longitudinal extent of the distal prosthetic component, and wherein the knee joint is assigned a force transmission device in the form of a mechanical or hydraulic force transmission device which, in the stance phase, converts the linear and longitudinal displacement of the distal prosthetic component in the direction of the knee joint axis into a flexion moment about the knee joint axis.
