    摘要： The invention relates to an artificial meniscus part for a knee-joint prosthesis that has on an upper side at least one femoral joint surface for the movable mounting of an artificial, natural or machined condyle of a femur, wherein the at least one femoral joint surface is configured in the form of a depression facing away from the meniscus part wherein the depression has an anterior and a posterior end region and a width of the depression has a minimum between the anterior and the posterior end region.An improved meniscus part set, an improved knee-joint prosthesis and an improved knee-joint prosthesis set are further proposed.

    摘要： In accordance with the invention a knee joint endoprosthesis comprises a femoral component and a meniscal component mounted for movement relative to and on said femoral component. Said femoral component comprises a medial and a lateral condyle having a medial and a lateral condylar surface. Said meniscal component comprises a medial and a lateral joint surface on which the medial and lateral condylar surfaces bear at least partially. Said medial condyle and said medial joint surface are shaped so as to form a rotary joint with a rotary joint center. Moreover, a rolling motion guiding device is provided for defined rolling of the lateral condylar surface and the lateral joint surface on each other along a curved path which is defined in dependence upon an angle of flexion between femoral component and meniscal component and extends around the rotary joint center.
