It commonly causes pain in the front of the thigh and can affect knee straightening strength. It is often discussed in sports medicine, orthopedics, and physical therapy after sprinting, kicking, or sudden deceleration. It is used as a clinical diagnosis to describe a pattern of symptoms, exam findings, and (when needed) imaging results."}
