A 21-year-old member asked:

My joints crack when I move. Am I at risk for arthritis?

Dr. Robert Kwok
Pediatrics 33 years experience
Not just from noises: Cracking a joint moves the parts of the joint, with the cracking noise coming from cartilage surfaces sliding, from movement of a little air-space from one place in the joint to another, or from some other non-traumatic event. A person with no joint pains before or after cracking a joint is probably not damaging the joint. However, making it a frequent habit has uncertain long-term effects.
