Tibial component (10) of a knee-joint endoprosthesis with a flat tibial bearing surface (11), a bearing body (12) that is slidably seated thereon and comprises two concave bearing dishes (13) in which a femoral component can be movably seated, and with a rotational guide means that guides the rotation of the bearing body (12) on the tibial bearing surface (11) about an axis (14) perpendicular thereto. The guide means comprises a bearing post (15) in the form of a regular cylinder that stands upright on the tibial bearing surface (11) and has at least one projection (16, 17) extending radially outward. The bearing post so constructed can be inserted into a post receptacle (19) that is formed on the underside of the bearing body (12) with a receiving groove (20) corresponding to the post projection (16, 17). The at least one post projection (16, 17) extending radially outward is spaced apart from the free end (24) of the post.
