Abstract
An apparatus and a method for determining and adjusting the optimal relative position of several functional surfaces of a condyle or of a socket of a human or artificial joint, especially for use with an endoprosthesis for the human knee joint, is provided. The apparatus is furnished with a compartment that is moveable by means of a sliding guide relative to a receptacle that can be detachably affixed to a human joint or bone region. A reference position of the compartment—relative to the receptacle—resulting from the posterior-anterior and/or medial-lateral motion of the knee joint can be established using by a marking having a scale.
