The invention relates to a knee-joint prosthesis with a hydraulic damping cylinder (1) for regulating the swing phase control and stance phase stabilization, and with an electronic control for a force field acting on the hydraulic fluid of the damping cylinder (1), the viscosity of the hydraulic fluid being able to be changed by the force field. The object of the present invention is to make available a knee-joint prosthesis whose electronic control has a high degree of safety and a minimal power consumption. According to the invention, the object is achieved by the fact that an actuating member (6, 7, 9, 12) is provided which generates a permanent force field and acts on the hydraulic fluid with an existing force field which is weakened or strengthened by the electronically controlled force field.
