A knee prosthesis with a flexion hinge which is formed by a hinge fork with two branches lying opposite each other, by a center part which is to be fitted in the hinge fork transversely with respect to the flexion axis of the latter, and by a hinge pin which, after the center part has been fitted into the hinge fork, is to be mounted, by movement in its longitudinal direction, in aligned hinge bores of the hinge fork and of the center part. So as not to have to push the pin into the prosthesis from the outside, it is formed by two pin stumps which, in an assembly position, are arranged inside the center part and, in a mounted position, partially protrude from the latter.
