What is the meaning of crepitus in a clinical context?

Crepitus in a clinical context refers to a crackling, popping, or grinding sound or sensation that occurs during movement, particularly at joints. This phenomenon can arise from various underlying conditions, including air in the soft tissues, rough surfaces of cartilage, or the movement of tendons over bones. It often serves as a diagnostic sign and can accompany joint pathologies such as osteoarthritis or tendinitis. Understanding this term is crucial for healthcare providers, as it can inform clinical assessments and help guide treatment plans when evaluating joint health and functionality.
