Joint cavitation is a physiological phenomenon that occurs when a rapid change in joint volume creates a pressure differential, culminating in the formation and bursting of gas-filled cavities within synovial fluid. This process produces the familiar popping or cracking sound often associated with maneuvers such as knuckle-cracking. It may arise spontaneously during regular movement or be intentionally induced through certain therapeutic practices like chiropractic adjustments or osteopathic manipulative treatment.

The mechanism of joint cavitation has been studied extensively, primarily within the context of manual therapy disciplines. Notably, its occurrence is not associated with any deleterious effects on joint health, contradicting traditional warnings about habitual knuckle-cracking. The gas bubbles formed during cavitation consist mostly of nitrogen and carbon dioxide, which are naturally dissolved in synovial fluid for joint lubrication.

Understanding joint cavitation contributes to effective implementation of manipulative therapies and demystifies common misconceptions regarding joint noises. Despite its ubiquity in daily life and medical practice, it remains an intriguing subject in biomechanics research.
