Instabile Patella bei Kindern und Jugendlichen

Unstable patella in children and adolescents

Zusammenfassung

Die Luxation der Patella ist eine typische Erkrankung der Adoleszenz mit im Vergleich zu Erwachsenen höherem Reluxationsrisiko. Die Behandlung stellt aufgrund der offenen Wachstumsfugen trotz der Vielzahl der operativen Möglichkeiten eine Besonderheit dar. Bei Auftreten einer Erstluxation ist auch bei Kindern und Jugendlichen eine genaue Risikoabklärung erforderlich. Liegt ein ungünstiges Risikoprofil vor, muss eine primäre operative Stabilisierung unter Berücksichtigung der Risikofaktoren in Erwägung gezogen werden, da eine unbehandelte Instabilität bereits im frühen Erwachsenenalter zu irreversiblen Knorpelschäden am Patellofemoralgelenk führen kann.

Abstract

Acute patellar luxation is a typical injury in adolescence with a higher risk of reluxation compared to adults. Despite the multitude of surgical options the treatment represents a special situation due to the open growth plates. The occurrence of a primary dislocation necessitates an exact clarification of the risks, even in children and adolescents. In the case of an unfavorable risk profile, a primary operative stabilization must be contemplated, taking the risk factors into consideration as an untreated instability can lead to irreversible chondral damage of the patellofemoral joint, especially in early adulthood.
