What does it mean when your knees pop while squatting?

When your knees pop while squatting, it can be due to several factors, such as the movement of tendons or ligaments over the bones, the release of gas bubbles in the joint fluid, or minor cartilage irregularities. If there's no accompanying pain or swelling, it's often considered normal and not a cause for concern. However, persistent popping accompanied by discomfort may indicate an underlying issue, and consulting a healthcare professional is advisable.
