Is it true that cracking your knuckles gives you arthritis?
High agreement — the answer is well-supported across models.
Models agree on
- ✓No evidence that knuckle cracking causes arthritis
- ✓Multiple studies and institutions confirm this conclusion
- ✓Repetitive cracking may lead to reduced grip strength or minor injuries
- ✓Dr. Donald Unger's 2009 IgNobel Prize-winning study supports this conclusion
No, there is no evidence that cracking your knuckles causes arthritis. Multiple studies and reputable institutions—including Johns Hopkins Arthritis Center, UAMS Health, Northwestern Medicine, Mission Health, and Arthritis UK—confirm that habitual knuckle cracking does not increase the risk of arthritis. Notably, Dr. Donald Unger’s 2009 IgNobel Prize-winning study concluded that there is no apparent relationship between knuckle cracking and the development of arthritis in the fingers.
While knuckle cracking does not cause arthritis, there are some potential downsides to consider:
- ·Temporary joint soreness or swelling may occur.
- ·Long-term habitual cracking may lead to reduced grip strength.
- ·In rare cases, repetitive cracking could cause minor ligament injuries or tendon dislocations, though these typically improve with conservative treatment.
It’s also worth noting that individuals with existing osteoarthritis may exacerbate their symptoms by cracking their knuckles repeatedly, though this does not cause arthritis itself. In summary, while knuckle cracking may not be beneficial, it does not lead to arthritis.
