title: MRI of the posterolateral corner of the knee: normal appearance and patterns of injury.
abstract: The posterolateral corner (PLC) of the knee is a complex area, previously poorly understood by radiologists. Numerous structures make up the PLC, whose evaluation is difficult because of the variable presence of the individual components, their intimate and commonly overlapping insertions, and their oblique course on traditional imaging planes. The clinical relevance of PLC injuries, especially the infrequently repaired "minor" components, adds to the confusion. Our purpose is to review the anatomy, imaging, clinical evaluation, and treatment options for PLC injuries.
