ABSTRACT OF THE DISCLOSURE An artificial joint for the replacement, in particular, of human joints, consisting of at least two joint sections (21,22) with spherical functional surfaces moving in relation to each other, wherein the relation to one another of the curvature of the functional surfaces (23,24) featuring a circular section contour are convex-convex, convex-concave or concave-concave, and the geometry of the joint is determined by means of a joint line with two joint axes progressing through the centers of rotation M1,M2 of the functional surfaces with the radii R1,R2, where R1 is the radius of the circular section contour of the functional surface with the midpoint M1 and R2 is the radius of the circular section contour of the functional surface with the midpoint M2, and where a pressure distribution body (25), the slide faces (26,27) of which feature a curvature adapted to correspond to the functional surfaces, is arranged between and supported by the two functional surfaces (23,24) of the joint sections (21,22), where the slide faces (26,27) of the pressure distribution body (25) are approximately the same size.
