Zusammenfassung
Die physiologische Funktion des Patellofemoralgelenks (PFG) wird durch die Interaktion verschiedener anatomischer und biomechanischer Faktoren bedingt. Viele patellofemorale Krankheitsbilder entstehen auf der Grundlage von Dysbalancen, die auf Abweichungen dieser Faktoren zurückzuführen sind und die komplexe Kinematik des PFG in relevantem Ausmaß beeinträchtigen. Die resultierenden Patholgien lassen sich drei große Symptomkomplexe einteilen: vorderer Knieschmerz, Arthrose und Instabilität. Die erfolgreiche Behandlung dieser Krankheitsbilder setzt eine genaue Kenntnis sowie eine gründliche klinische Analyse zugrundeliegender Pathologien voraus. Im Folgenden sollen die biomechanischen Grundlagen aktiver, passiver und statischer Stabilisatoren des PFG sowie deren Einfluss auf die patellofemorale Kinematik erörtert und dargestellt werden. Zudem soll ein Überblick klinischer Untersuchungsmethoden zur Diagnose einzelner Pathologien gegeben werden.
Abstract
The complex physiological function of the patellofemoral joint depends on the dynamic interaction of various anatomical and biomechanical factors. Many patellofemoral disease symptoms are the result of an imbalance due to deviations of these factors, which impair the complex patellofemoral kinematics to a relevant extent. The resulting pathological conditions can be classified into three major symptom complexes: anterior knee pain, osteoarthritis and instability. An exact understanding of potential underlying pathological conditions and a thorough clinical analysis are mandatory and absolute prerequisites for successful treatment. The aim of this article is to present and discuss the biomechanical principles of static, passive and active stabilizers of the patellofemoral joint as well as their influence on the patellofemoral kinematics. In addition, it provides an overview of the clinical examination methods for the diagnosis of the individual pathological conditions.
