Abstract
With the invention is shown a meniscus platform for an artificial knee joint, which consists of a metal platform (1) and a metal slide member (3) sliding thereon at right angles to the tibia axis (17), which on its upper side comprises sliding surfaces (4, 5) and a guide bead (8) for the condyles (13, 14) of a femur part (11). The sliding movement between the metal slide member (3) and the metal platform (1) is restricted by a guiding pin (10) in the metal platform, which engages in an oblong hole (9) in a slide member (3) made of metal. The metal slide member (3) can rotate around the guiding pin (10) and can be displaced along its oblong hole (9). The rotational movement of the slide member (3) is restricted by a limiting recess (15), which encloses a part of the eminentia (19) in the region of the rear cruciate ligament.
