Habitual knuckle cracking causes joint damage.

the verdict
CONTESTED PARTIAL
Recorded sources
2 sources for · 2 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that Habitual knuckle cracking causes joint damage?

Partly. The retrieved studies do not settle whether habitual knuckle cracking damages joints. The largest study found no excess hand arthritis among habitual crackers but did report more hand swelling and lower grip strength, while a small student study linked cracking to hypermobility and functional hand impairment; a blinded study found no immediate adverse findings.
