Medical Mythbuster: Does Cracking Your Knuckles Cause Arthritis?

Growing up, our parents sometimes warned us that cracking our knuckles will “cause arthritis.” Fortunately, those who like to lean back in their chair and give their knuckles a good crack probably don’t have too much to worry about. There is no medical evidence that habitual knuckle-cracking leads to arthritis.

The sound of the knuckle-cracking is believed to be caused by the joints in the fingers rapidly separating and forming a gas bubble which quickly collapses. It is true that repeatedly cracking your joints can sometimes cause soreness (as well as possibly irritate your coworkers) so it’s best not to overindulge!
