Abstract
Artificial joint for replacing human joints in particular, consisting of at least two joint parts with spherical functional surfaces that can move relative to each other. 2 The curvature relationships of the functional surfaces having a circular cross-sectional contour are convex/convex, convex/concave or concave/concave relative to each other, and the geometric design of the joint is determined by a joint chain with two joint axes running through the centers of rotation M.sub.1 and M.sub.2 of the functional surfaces with radii R.sub.1 and R.sub.2, where R.sub.1 is the radius of the circular cross-sectional contour of the functional surface with center of rotation M.sub.1, and R.sub.2 is the radius of the circular cross-sectional contour of the functional surface with center of rotation M.sub.2.
