Why do our joints click or crack sometimes?

Quick Answer
The sound often comes from gas bubbles forming and collapsing in the joint fluid. It can also come from tendons moving over bones.
The Full Story
Synovial joints contain fluid that lubricates movement. When a joint is stretched or bent, pressure changes can cause dissolved gases to form bubbles and then collapse, creating a popping sound. In other cases, the sound comes from ligaments or tendons shifting position over bone. In the absence of pain, cracking joints is usually harmless.
Key Facts
1.Gas bubbles in synovial fluid can create pops
2.Tendons or ligaments can also cause clicking sounds
3.Painful or swollen joints should be checked by a clinician
