Crepitus is the term used to describe the cracking, popping, or grinding sounds that can occur when a person moves their joints. It is most commonly heard in the knees, shoulders, and fingers. Crepitus can be caused by a variety of factors, including changes in joint cartilage, gas bubbles within the joint, tendons or ligaments moving over bony surfaces, or joint misalignment. In most cases, crepitus is harmless and does not require treatment. However, if accompanied by pain, swelling, or other symptoms, it is recommended to consult with a healthcare professional.
