Zusammenfassung

Die Magnetresonanztomographie (MRT) des Kniegelenks ist eine robuste Methode zur Beurteilung von Binnenläsionen. Bei Kenntnis der technischen und anatomischen Fallstricke lassen sich pathologische Veränderungen meistens sicher abgrenzen. Problematisch bleibt die Differenzierung meniskokapsulärer Läsionen von normalen anatomischen Strukturen. Die hohe Prävalenz asymptomatischer Befunde, z. B. Meniskusrisse bis zu 63% auf der asymptomatischen Gegenseite, stellt auf der anderen Seite ein Management-Problem für die behandelnden Ärzte dar.

Abstract

Magnetic resonance (MR) imaging of the knee is a robust method for the evaluation of internal derangements. A knowledge of the well known technical and anatomical pitfalls avoids, in most cases, diagnostic errors. However, the differentiation between meniscocapsular separation and normal anatomy remains challenging. The high prevalence of abnormal MR findings, especially meniscal tears with up to 63% on the asymptomatic contralateral side, has to be considered in patient management.
