- description: Using MRI, researchers recorded in real-time what happens inside a joint when it cracks.The joint separation was associated with rapid creation of a gas-filled cavity within the synovial fluid, a slippery substance that lubricates the joints. Rapid cavity inception at the time of joint separation may cause the popping sound heard. Credit: Real-Time Visualization of Joint Cavitation Gregory N. Kawchuk, Jerome Fryer, Jacob L.
