Abstract (en)

[origin: WO9517860A1] The invention concerns a knee endoprosthesis with a femur-mounted component (10), a tibia-mounted component (11) and, located between the femur-mounted and tibia-mounted components, a bearing body (12) made of plastic, in particular polyethylene, the bearing body (12) resting against a cup-shaped bearing surface (20) located on the tibia-mounted component (11) and facing the femur-mounted component (10) to form a slip joint. Jutting out from the bearing surface (20) on the tibia-mounted component is a stud-like or pin-like stop (21) which projects into a slot-shaped hole (22) in the bearing-body slip surface (32), which faces the bearing surface (20) on the tibia-mounted component, such that the bearing body (12) can be rotated on the bearing surface (20) on the tibia-mounted component and can also move longitudinally to a limited extent in the plane in which the knee bends.
