Die Erfindung betrifft ein Planungsunterstützungsverfahren für die Korrektur von Gelenkelementen, bei dem- die Ist-Form mindestens eines interessierenden Teils des Gelenkelements (17) erfasst und computergestützt eingelesen bzw. gespeichert wird- die Ist-Form computergestützt mit der Soll-Form verglichen wird und- die Vergleichsdaten, insbesondere die Abweichungen zwischen Ist- und Soll-Form, zur computergestützten Planung der Abrasion von abzutragenden Gelenkelementteilen (17) verwendet werden.The method involves detecting an actual shape of specific part of a joint element (17) using an endoscope camera (13), and reading and storing the actual shape of the specific part using a computer. The actual shape of the specific part is compared with a reference shape of the specific part, where the reference shape is defined from patient data and model data of the joint element. A deviation between the actual and reference shapes of the specific part is utilized for computer-aided planning of abrasion of the specific part. Independent claims are also included for the following: (1) a program having instructions for performing a method for assisting a planning for correcting a joint element and/or joint bone of a patient (2) a computer program storage medium having instructions for performing a method for assisting a planning for correcting a joint element and/or joint bone of a patient.
