What the research says
A case-control study of 215 people found no association between knuckle cracking and osteoarthritis of the hand, and a radiographic study reached the same conclusion. One physician famously cracked the knuckles of one hand only for over 60 years and found no difference between hands. Some studies report reduced grip strength or hand swelling in habitual crackers, but the arthritis link is not supported.
Caveats
- Evidence is observational and sample sizes are modest.
- Painful or persistently swollen joints should still be assessed.
