description | The invention relates to an artificial joint (3), designed in particular to replace a talocrural joint. Said joint comprises a first primary joint surface (1) that forms an articular fossa (4), designed to replace in particular the tibia and that consists of concave curvatures running parallel to a primary function plane of the joint (3), which corresponds to the sagittal plane and comprises a second primary joint surface (2), which co-operates with the first primary joint surface (1) as a component of a condyle (5) that replaces in particular the talus and has convex curvatures (7, 8, 9, 10) on the primary function plane that are adapted to the first primary joint surface (1). The aim of the invention is to obtain a high stress resistance and optimal mobility of the joint (3), subject to the respective joint position. To achieve this, the radii of the curvatures (7, 8, 9, 10) are calculated in such a way that the differential amounts arising between the corresponding radii of the first primary joint surface (1) and the second primary joint surface (2) in an ascending angular position (V) in relation to a descending angular position and also simultaneously between a medial face (11) and a lateral face (12) of the joint (3) deviate from one another. |
