Abstract: An orthopedic knee joint having an upper part with upper connecting features, a lower part which is mounted pivotably on the upper part and has connecting features for prosthetic components, and a stop for limiting an extension movement. The stop is coupled to an adjusting device, which is coupled to a control device that actuates the adjusting device as a function of sensor data and changes the position of the stop. If the knee joint is provided with an adjustable extension stop position, the extension stop can be shifted forward for walking which results in a greater inclination at heel strike in order to flex the knee joint and, therefore, increased damping upon initiation of the stance phase. For standing, the adjusting device can be activated so that the extension stop is reversed, such that a statically more secure orthosis or prosthesis set-up can be obtained.
