It is commonly discussed in sports medicine, physical therapy, and orthopedic care when evaluating leg, hip, or knee symptoms. People often use the term to describe a \u201cpulling\u201d feeling with bending forward, straightening the knee, or walking quickly. Clinicians use it as a symptom description and as an exam finding, not as a single diagnosis by itself."}
