[The significance of axial misalignment as a pre-osteoarthrotic deformity, and its radiological assessment].

Pathological misalignment of the axis of the leg in the frontal plane should always be considered as predisposing to osteoarthrosis of the knee joint. This is especially relevant with increasing age. Complete radiological investigation of the leg with the patient standing allows determination of the site and degree of any axial deviation and calculation of the required angle of correction. In the light of these considerations it is apparent that correction of pathological axial misalignment of the leg is not only justified but necessary.

[Interaction between construction and fixation of knee endoprostheses (author's transl)].

The two completely different total knee-endoprostheses (hinge type and sled or runner type) have been compared concerning construction and ability for take up or transmission of forces and moments. The difference to the real knee joint are described. The reactions on fixing of endoprostheses in the bone caused by the construction are emphasized. By a systematic analysis of the so called sled-prostheses is to be shown to differantiate between real sled-prostheses with rotation and sliding mobility and pseudo-sled-prostheses (better rotation-segment-prostheses). They have only one possibility of rotation to realize the knee bending. The kind and number of existing "degrees of freedom" are used as a significant characteristic to differentiate the various endoprostheses principles and their variants. This study should mainly inspirate for a systematic comparison of efficiency of the different types of knee-endoprostheses. This should give the operating surgeon for a length of time an objective aid to decision.
