Abstract

What is described is a leg-supporting means for making restrained X-ray photographs of the knee joint. In order to obviate the disadvantages of the apparatus which are on the market for making X-ray photographs of the knee joint, more especially the unstable position of the proband leg and shift instabilities with small degrees of flexion, provision is made for a thigh section or member with two clamping members movable concentrically relatively to one another to be connected to a ring enclosing the X-ray zone for the knee joint, and for the ring with the thigh member to be rotatable relatively to a lower leg member about its center and by up to 90.degree. towards both sides.
