A knee-joint endoprosthesis includes a femoral part having, at the lower end, two condylar pans, and a tibial part having a tibial plateau with upper support areas for supporting, and also for guiding the condylar pans with movements of the knee joint. The condylar pans each have a downwardly-running lateral wall, which, at its convexly-curved lower end passes over into a support surface running transversely outwardly. The condylar pans each have, ventrally at the transition from the lateral wall to the support wall, a recess directed toward inside of the pan, across which an intervening space between the condylar pans is widened such that, with stronger bending, the knee cap can enter into this widened zone of entry of the intervening space.
