Knee prosthesis with a flexion hinge which is formed by a hinge fork with two branches (8) lying opposite each other, by a centre part (14) which is to be fitted in the hinge fork transversely with respect to the flexion axis (19) of the latter, and by a hinge pin which, after the centre part (14) has been fitted into the hinge fork, is to be mounted, by movement in its longitudinal direction, in aligned hinge bores (11, 20) of the hinge fork and of the centre part (14). So as not to have to push the pin into the prosthesis from the outside, it is formed by two pin stumps (12, 13) which, in an assembly position, are arranged inside the centre part (14) and, in a mounted position, partially protrude from the latter.
