Abstract
A device for determining the optimal dimensions of the components of a knee endoprosthesis, including A) an angular element (7) having a first anterior plate (9) and a second distal plate (10) that is arranged at right-angle thereto; B) a first caliper (16) that is arranged on the second plate (10) in a manner that permits it to be displaced parallel to the central axis (19) and to be arrested, and which has a bearing surface (25), the bearing surface being essentially parallel to the first plate (9) and provided for resting against a tibial plateau (29) when a knee joint is bent; and, C) a second caliper (11) that is arranged in a manner that permits the second caliper to be displaced parallel to the longitudinal axis (8) of the first plate (9) and to be arrested, and which has a bearing surface (24), the bearing surface being essentially parallel to the inner side (23) of the second plate (10) and provided for resting against the tibial plateau (29) when the knee joint is straightened.
