The theory on how: Joints pop is due to cavitation. When the joint is ‘cracked’ the volume within the joint capsule is increased through stretching. When this occurs, the pressure drops within the synovial fluid which causes the small amounts of air dissolved within the fluid to come together and form bubbles. They then collapse on themselves. The formation of these bubble and collapse via cavitation causes the pop.

May not be a problem: Some people just have joints that pop.
