Pictorial Essay


Knee trauma is a common presenting symptom in the emergency setting. Avulsive knee injuries are important to diagnose timely and accurately to avoid unnecessary patient morbidity. Many of these avulsive knee injuries have characteristic appearances on imaging. This article presents a comprehensive review of some of the most common types with real cases used for imaging correlation.
