Zusammenfassung

Das funktionelle Zusammenspiel von knöchernen und ligamentären Strukturen ist für eine physiologische Kniekinematik von herausragender Bedeutung. Trotz aller technischen Fortschritte und wissenschaftlichen Bemühungen ist noch immer unzureichend geklärt, welche Bedeutung der Anatomie des Tibiaplateaus, und insbesondere ihrer dorsalen Inklination (tibialer Slope), zugeschrieben werden soll. Allen Empfehlungen ist gemein, dass eine valide und reproduzierbare Methodik zur Bestimmung des tibialen Slope benötigt wird. Insbesondere bei der Verwendung von nativen Röntgenaufnahmen muss bedacht werden, dass es sich lediglich um eine zweidimensionale Annährung einer komplexen dreidimensionalen Oberfläche handelt und die individuellen Unterschiede des medialen und lateralen Tibiaplateaus unzureichend berücksichtigt bleiben werden. Der vorliegende Artikel erläutert die verschiedenen Modalitäten und Techniken der radiologischen Bestimmung des tibialen Slope sowie seine Verteilung in der Normalbevölkerung.

Abstract

The functional interaction of bony and ligamentous structures is of outstanding importance for physiological knee joint kinematics. Despite all the technical advances and scientific efforts, there is considerable controversy in the recent literature regarding the importance of the bony anatomy of the proximal tibia and in particular its dorsal inclination (tibial slope); however, general consensus has been reached that a valid and reproducible methodology for the assessment of the tibial slope is required. It must be borne in mind that each assessment is only a two-dimensional approximation of the complex three-dimensional tibial plateau, particularly when using native X‑ray images and that possible differences between the medial and lateral tibial compartments are insufficiently accounted for. This article gives an overview of the numerous modalities and techniques for radiological assessment of the tibial slope and its distribution among the general population.
