Daher sollte die Erstluxation, wie auch die Rezidivluxation, umfassend bez\u00fcglich des Verletzungsmusters und der anatomisch-pr\u00e4disponierenden Risikofaktoren diagnostiziert werden. Dies erm\u00f6glicht die Anwendung von Risikostratifizierungsmodellen zur Beurteilung des Rezidivrisikos einer Luxation und kann damit die therapeutische Entscheidungsfindung unterst\u00fctzen. Die MPFL-Plastik hat sich als erfolgreiche Therapie zur Behandlung der Patellainstabilit\u00e4t etabliert. Jedoch ist oftmals eine erg\u00e4nzende Korrektur kn\u00f6cherner Risikofaktoren notwendig bzw. empfehlenswert. Dabei kommt der pr\u00e4operativen Auspr\u00e4gung des J-Signs und der dynamischen Beurteilung der Patellainstabilit\u00e4t (dynamischer Apprehension-Test) entscheidende Bedeutung zu, die in der
