88/100

Habitual knuckle cracking has not been shown to cause hand osteoarthritis, although studies report possible associations with swelling, grip strength, and rare acute injuries.

~ Both Sides ~

For The Claim

Habitual crackers in one study had more hand swelling and lower grip strength.
Forceful manipulation has been associated with acute soft-tissue injuries.
The available studies are mainly observational and cannot establish that cracking is harmless in every circumstance.

Against The Claim

A radiograph-based study found similar OA prevalence in crackers and non-crackers.
A 300-person study found no higher prevalence of hand arthritis among habitual crackers.
A clinical review found no association between decades of habitual cracking and clinical or radiographic OA.

Bottom Line

The evidence does not support the claim that cracking knuckles causes arthritis. Some studies report possible swelling, grip-strength differences, or rare injuries, especially with forceful manipulation.

~ What We Couldn't Find ~

Most evidence is observational rather than randomized, so it cannot prove that cracking is harmless in every circumstance. Researched by AI. Sources linked. Verify independently.
