Patellar Instability



The symptomatic patello-femoral compartment can have a broad spectrum of causes and presentations. Anterior knee pain can be present without apparent pathological clinical findings. The etiology is ill-defined and patellar maltracking alone cannot explain all clinical presentations, especially the pain at rest. A history of trauma may lead to recurrent dislocations and instability if additional anatomical morphological abnormalities are present. Thus, numerous factors have to be evaluated in order to improve the accuracy of determining the cause of the symptoms.
