Abstract
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.
