title: [Measures for biomechanically correct positioning of knee joint endoprostheses].
abstract: Normal post-operative function, permanent stable fixation and long life for the implant material are determined mainly by the correct biomechanical positioning of the knee joint prosthesis. We have identified six measures within the surgical procedure that are of vital importance for achieving biomechanically correct positioning. Because of their great importance, we call these measures "The Golden Six", and describe their application using the ESKA Resurfacing Knee System (RKS). This system, which is so designed that it enables a maximal bone saving resection technique, makes use of a diagonal screw-fixation of the endoprosthetic elements, resulting in increased primary stability. For the safe and reliable implementation of our measures, we have developed a special set of instruments. Anatomical, kinematic and surgical studies have shown that with the aid of the above-mentioned six measures biomechanically correct positioning of all the implanted elements can be achieved, thus ensuring trouble-free post-operative function of the knee joint and the least possible mechanical stressing of the implanted materials.
