How Does the “Crack” Sound Come?

How the 'cracking' sound comes when the fingers are pulled or bent may be explained this way: Finger joints, like other joints in the body, contain a fluid called synovial fluid, which is in a small bag or compartment in the joint. This bag is stretched when you crack your knuckles, causing it to pop. The crack is heard when carbon dioxide is released as the bag pops. The bag refills in a few minutes, after which cracking may be heard again when the fingers are stretched or bent.

Stretching may be relaxing and can help reduce joint stiffness after many hours of writing, typing, painting, or other tasks. However, the relaxing effect is temporary.

  • Some people warn that cracking the knuckles will lead to arthritis, a chronic condition of the joints characterized by pain, stiffness, inflammation and swelling. However, studies show that there is no link between knuckle cracking and arthritis. Although arthritis is not a risk, knuckle cracking can have other undesirable consequences.
  • People who pull and bend their fingers to produce a cracking sound may overstretch their ligaments and cartilages (soft tissues that surround the joint). Over time, this may lead to soft tissue injury and inflammation. Cracking knuckles can cause swelling of the finger joints, although this is not always direct effect of knuckle cracking. Watch out for pain, because knuckle cracking should not be associated with any pain and may be a sign that something else is wrong with the finger joints.
