It is a clinical term used by orthopedic teams to describe a pattern of symptoms and exam findings, not a single disease. It can occur soon after surgery or develop gradually months to years later. The term is commonly used in clinic notes, physical therapy documentation, and revision knee replacement evaluations."}
