Habitual knuckle cracking increases the risk of hand injury.

the verdict
CONTESTED PARTIAL
Recorded sources
3 sources for · 1 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 increases the risk of hand injury?

Partly. One older study of 300 patients and a small cross-sectional study of 150 students report links between habitual knuckle cracking and impaired hand function, while a 2018 review says observational evidence has failed to show an association with osteoarthritis. The evidence is mixed and only partial, covering specific populations and outcomes rather than the general claim.
