What is cracking of knuckles?
Cracking of knuckles, also called knuckle cracking, is the intentional manipulation of the finger joints to produce a popping or cracking sound. It is done by pulling on or twisting the finger, which causes a synovial fluid-filled cavity in the joint to suddenly collapse and then quickly refill, producing the characteristic sound.
