[How I explore… a non-traumatic gonalgia]

Because the knee is the joint of the human body with the largest surface, it is no wonder that gonalgia is one of the most common complaints in the general population. Although the management of a painful traumatic knee is relatively well standardized, that of a non-traumatic knee pain is less codified. History and a rigorous systematic clinical examination play a key role in the management of nontraumatic gonalgia. The diagnostic approach is mainly guided by the inflammatory or mechanical nature of the pain and its topography. This article aims to clarify the diagnostic approach to gonalgia without notion of prior trauma.
