The popping sound usually comes from air seeping into the soft tissue, finding its way into the area around the joint and causing tiny bubbles in the synovial fluid. When a person bends or stretches their knees, the bubbles can burst with a popping or cracking sound. This may sound alarming, but it is usually harmless.

When I stretch my leg my knee pops?

What does it mean if your knee pops when you extend it?
This type of popping symptom is often a sign of a meniscus tear or a loose piece of cartilage within the joint. 1 These are tissues inside the knee that help cushion and protect the joint.
