What is articular crepitus?

Crepitus is a palpable or audible grating or crunching sensation produced by motion. This sensation may or may not be accompanied by discomfort. Crepitus occurs when roughened articular or extra-articular surfaces are rubbed together by active motion or by manual compression.

What is the cause of Crepitation?

Crepitus is caused by tissues rubbing together in an abnormal way. The most common cause of crepitus is rough cartilage and bone rubbing together in a joint, and the most common cause of this type of crepitus is arthritis or joint injury.

What is Crepitation of the knee?

Share on Pinterest Crepitus of the knee refers to a cracking or popping sound or sensation in the knee joint. When the pressure between the kneecap and the femur is greater than usual, the cartilage in the joint can start to soften and wear away.

Is joint Crepitation normal?

Often, crepitus is harmless. It happens when air seeps into the soft tissues around the joint (such as the kneecap). When you bend the joint, the air bubbles burst, and you hear a cracking sound. While most crepitus is harmless, some forms of crepitus signal a problem.

What is patellofemoral Crepitation?

Abstract. Physiological patellofemoral crepitus (PPC) is the vibration signal produced by the knee joint during slow motion (less than 5 degrees per second), which can be measured by vibration arthrometry (VAM).

Does knee crepitus lead to arthritis?

Knee crepitus typically happens when the knee is bent, such as when you are squatting, going up or down stairs, or rising from a chair. By itself, crepitus generally is not a cause for concern. Once the cartilage gets rough, though, it may be at risk to begin to wear down, leading to arthritis.

Why do my joints make a grinding noise?

Rubbing and grinding When cartilage deteriorates it creates a rough surface and can even leave parts of bone exposed, Vagg says. The creak and grind of crepitus occurs when the rough surfaces or exposed parts of bone rub against each other. This is osteoarthritis and the noise is most common in the knee and the neck.
