Zusammenfassung
Neue Erkenntnisse über die Pathophysiologie und Biomechanik des patellofemoralen Gelenks (PFG) schaffen ein besseres Verständnis und erlauben neue therapeutische Ansätze. Entscheidend für eine erfolgreiche Behandlung ist die Analyse der zugrunde liegenden Pathologie. Im vorliegenden Beitrag werden die biomechanischen Grundlagen der statischen, passiven und aktiven Faktoren und ihr Einfluss auf das PFG beschrieben. Die Patienten werden klinisch und bildgebend mit einer Basisdiagnostik in die 3 Krankheitsbilder Schmerz, Instabilität und Arthrose eingeteilt. Bei Vorliegen einer PFG-Instabilität erfolgt eine weiterführende Diagnostik mit der Magnetresonanztomographie (MRT). Ziel dieses zusätzlichen MRT-Einsatzes ist die Analyse der biomechanischen Ursachen für die Instabilität. Auf Basis eines pathophysiologischen Konzepts wird ein neuer therapeutischer Algorithmus zur Behandlung der 3 Krankheitsbilder vorgestellt.
Abstract
New knowledge about the pathophysiology and biomechanics of the patellofemoral joint (PFJ) has led to a better understanding and new treatment options. To recognise the main pathology is the most important and difficult part. This article describes the basic principles of biomechanics (static, passive and active factors) and their influence on the PFJ. Patients are classified into three groups (pain, instability and arthritis). This is achieved by a clinical evaluation and standard X-rays. The instability group is analysed additionally with MRI. The aim of this evaluation is to analyse the biomechanical cause of the instability. Based on a pathophysiological concept a new therapeutic algorithm is introduced.
