1. A system comprising: a guide with an external contour substantially corresponding to the receiving part of the joint, the guide defining an axis that has a known position relative to the joint when the guide is joined to the joint； the first reference device for attaching to the joint bone； the second control - reference device for connection with a known alignment relative to the guide； a control unit capable of exchanging data with the first reference device and the second reference device, wherein the control unit is configured to determine an axis position relative to the first reference device based on data that indicate the position of the second reference device with respect to the first reference device reference device, while the second reference device is in a known alignment with the guide, and the guide with tykovana with sustavom.2. The system according to claim 1, characterized in that the axis has a known angle of deviation and a known angle of inclination forward relative to the joint with a guide attached to the joint. The system according to claim 1, characterized in that the second reference landmark is configured to attach to the guide in a position with a known offset relative to the axis. The system according to claim 1, characterized in that the outer contour of the guide before using the guide is formed so that the outer contour largely corresponds to the receiving part of the joint, and the guide is connected to the receiving part of the joint in one orientation1. Система, содержащая:направляющую с внешним контуром, в значительной степени соответствующим принимающей части сустава, при этом направляющая определяет ось, которая имеет известное положение относительно сустава при стыковке направляющей с суставом；первое контрольно-ориентирное устройство для прикрепления к кости сустава；второе контрольно-ориентирное устройство для соединения с известным выравниванием относительно направляющей； иблок управления с возможностью обмена данными с пе
