Disruption of the proximal tibiofibular joint in the setting of multi-ligament knee injury.
Instability of the proximal tibiofibular joint is a relatively uncommon condition when in isolation; however, instability of the proximal tibiofibular joint is far more frequent in those presenting with a severe multi-ligament injury of the knee. If this joint is left unstable, repair of a co-existent injury of the posterolateral corner may fail, regardless of the proficiency of the technique. We present two patients with disruption of the proximal tibiofibular joint, including the MRI appearance, who initially presented to our hospital for management of significant polytrauma, as well as multi-ligament injury of the ipsilateral knee.
