Zusammenfassung

Die mediale Stabilität stellt ein komplexes Konzept dar und beinhaltet, dass sich die Bandstrukturen in Flexion und Extension unterschiedlich verhalten. Kontraktur und Dehnung, aufgrund von Deformität und Osteophyten, wirken sich auf diese Ligamentstrukturen ungleichmäßig aus. Nachdem die Knochenoberflächen zwecks Varus-Valgus-Ausrichtung korrekt reseziert sind, führen sie in Flexion und Extension häufig zu unterschiedlichen Straffheits- oder Laxizitätsgraden. Die Distorsion der Gelenkfläche kann auch dazu führen, dass sich die Varus-Valgus-Ausrichtung in Beuge- und Streckstellung unterschiedlich verhält. Bestimmte Anteile des medialen Stabilisierungskomplexes des Kniegelenkes, die sich auf die Stabilität in Flexion oder Extension auswirken, bedürfen folglich gegebenenfalls der Anpassung.
