Popping or cracking sounds from the knees are very common, especially when you squat, climb stairs or stand up after sitting. In most cases, painless knee noise is harmless and is not a sign of damage. However, popping that comes with pain, swelling, stiffness, a feeling of the knee giving way or locking should not be ignored, as it may point to a ligament or cartilage injury or early arthritis. Staying active, strengthening the leg muscles and maintaining a healthy weight can support knee health. If knee sounds are accompanied by pain or affect your movement, consult an orthopaedic specialist for an evaluation.
