Abstract
An anchorage for tibia plates of knee joint endoprostheses which provides for each tibia plate of plastic a metal tray which carries the plate and is provided with one straight planar wall having on the inside surface thereof a T-shaped projection engaging with a T-shaped recess of the tibia plate. The metal tray has another side wall in the form of a circular arc which conically thickens from the top downwards to the base of the tray. The underside of the tray, including the base and lower webs thereof, is provided with a metallic open-cell coating or layer, into the cells of which bone tissue can grow in with subsequent formation of bone, so that the tray always remains joined to the shin bone, while the tibia plate is detachable and exchangeable.
