Q: I crack my knuckles all the time. Am I damaging my joints?
A: You may be grossing out your friends – some people consider the sound of cracking knuckles as odious as fingernails on a blackboard – but you are causing no harm to yourself, according to Dr. Andrew Terrono, chief of hand surgery, at New England Baptist Hospital.
Terrono said patients ask him this question all the time, and he tells them that the latest research suggests cracking knuckles will not cause arthritis or damage ligaments.
