It is quite common for knees to pop, crack or click when performing activities that involve body motions such as bending down, squatting and standing up.

A clicking or popping knee noise that causes pain or inflammation can be cause for concern because it may be connected to a knee injury called a meniscus tear. This is an injury that can occur from many contact sports and jogging. The meniscus is a type of cartilage that acts as a cushion in knee joints, states the American Academy of Orthopaedic Surgeons. This type of injury causes knee pain, inflammation and joint stiffness.
