Patella fractures are rare injuries, accounting for 0.5 - 1.5% of all fractures, but they can lead to severe functional limitations if they do not heal properly. In addition to a prompt diagnosis, surgical treatment is usually necessary for multi-fragment fractures. The goals of every treatment are a biomechanically stable joint as well as a congruent restoration of the retropatellar joint surface. These results often remain a challenge, especially in multiple fragment fractures. The surgical treatment strategies have steadily evolved from tension band and screw osteosyntheses in combination with wire cerclages. Currently, angular stable plate systems are increasingly being used. This article gives an overview of the fracture anatomy, the classification and diagnosis of patella fractures and the currently used surgical treatment options.
Patellafrakturen sind mit 0,5 – 1,5% aller Frakturen seltene Verletzungen, die jedoch bei inadäquater Ausheilung zu hohen funktionellen Einschränkungen fü̈hren können. Dieser Artikel gibt eine Übersicht über die Frakturanatomie, die Einteilung und Diagnostik von Patellafrakturen sowie über die aktuellen operativen Versorgungsmöglichkeiten.
