Tibialplatform for a knee-joint prosthesis and knee-joint prosthesis with such a tibialplatform

摘要

The through-bores (12) are each provided with a femur-side, upper sunken formation. At least one through-bore (12) unused for fixture is provided with a closure plug (15) insertable from above, which has a sealing surface supported in the sunken formation. The closure plug contains a number of bending springs insertable in the through-bore, with the wall of which they form a snap connection. The plug also has a hat-shaped central raised formation, which is provided with an upwardly open blind-bore to receive a setting tool. The sunken formations in the through-bores each have a dome shape, which is determined by a virtually spherical support surface for the fixture part (14).
