The Science of Cracking Knuckles

  • Knuckle cracking is related to bubbles in synovial fluid, which contains gases like oxygen, nitrogen, and carbon dioxide.
  • This fluid prevents finger bones from grinding together.
INSIGHT

The Sound of Cracking

  • The popping sound might be caused by the collapse of bubbles in the joints, rather than their formation.
  • This has been suggested by recent research using mathematical formulas and MRI studies.

Health Concerns
