Mit vermehrtem Einsatz von funktionellen Analysen wie der Bewegungsanalyse r\u00fcckt die Betrachtung der dynamischen Beinachse zunehmend in den Fokus. Die dynamische Achse des Kniegelenks spielt eine entscheidende Rolle f\u00fcr den Verschlei\u00df von Knie-Totalendoprothesen (K-TEP), da sie die Belastungsverteilung und Bewegungsmuster im femorotibialen Gelenk beeinflusst. Insbesondere das Knieadduktionsmoment (KAM) wirkt sich bei medialen Belastungen auf das Inlay aus, das bei hohen Belastungsfrequenzen Verschlei\u00df zeigt. Studien zeigen, dass das KAM bei Varusausrichtung steigt, was zu einer ungleichm\u00e4\u00dfigen Lastverteilung und einer erh\u00f6hten Belastung des medialen Kompartiments f\u00fchrt. In-vitro- und Post-mortem-Analysen quantifizieren den j\u00e4hrlichen Materialverlust im Inlay, wobei Design und Ausrichtung der Prothese die Verschlei\u00dfrate beeinflussen. Die dynamische Beinachse und das Gangbild k\u00f6nnen den Verschlei\u00df weiter modifizieren; ein \u201eToe-in\u201c-Gangmuster etwa senkt das KAM signifikant und k\u00f6nnte somit eine nichtoperative Option zur Verschlei\u00dfminderung darstellen. Neuere Ans\u00e4tze, wie das kinematische Alignment, streben eine nat\u00fcrliche Positionierung der Prothese an, was den Verschlei\u00df nicht zwingend erh\u00f6ht, jedoch im Vergleich zur mechanischen Ausrichtung eine pr\u00e4arthrotische Varus- oder Valgusachse belassen kann. Zusammenfassend k\u00f6nnte eine dynamische Bewertung der Beinachse zur pr\u00e4operativen Planung und zur Verschlei\u00dfreduktion bei K-TEP beitragen, wobei die statische radiologische Achsbestimmung klinisch relevant bleiben wird.<\/jats:p>","DOI":"10.1055\/a-2766-9763","type":"journal-article","created":{"date-parts":[[2026,2,13]],"date-time":"2026-02-13T00:06:20Z","timestamp":1770941180000},"page":"138-145","source":"Crossref","is-referenced-by-count":0,"title":["Die
