FACT CHECK #D7VP0MON

WHAT WE FOUND

Decades of clinical research and comparative studies consistently demonstrate that cracking your knuckles does not cause arthritis 4719. A study of 300 individuals found no increased preponderance of arthritis in habitual knuckle crackers compared to those who do not crack their joints 16. The popping sound is actually caused by negative pressure or gas bubbles forming and bursting within the synovial fluid of the joint 1017. Medical experts emphasize that there is no scientific basis for this claim and label it a common medical myth 1115. While the habit is not linked to arthritis, some research suggests habitual cracking may lead to reduced grip strength or hand swelling 116. One longitudinal experiment involving a subject cracking knuckles on only one hand for 50 years also found no difference in joint health between the two hands 6.
