Are you hearing popping and cracking noises every time you bend your knees?
Chances are, your muscles and connective tissues probably just need a good stretch.
Why Do My Knees Crack?
Tired of sounding like Rice Krispies in milk whenever you stand or sit? Cracking and popping in the knees can be the sound of fluid getting pushed about or it can be something more serious involving bones and connective tissues.
Cavitation occurs when joints move and the synovial fluid changes pressure, releasing carbon dioxide bubbles. This is common and no cause for alarm.
Some people may also feel a grinding sensation in the knees when squatting; if it doesn’t hurt, it’s known as benign crepitus.
If you experience knee pain when sitting or squatting, however, there may be more going on.
Crepitus (the non-benign kind) occurs when cartilage rubs against the bones and tissues in the joint, eventually wearing the cartilage and causing pain upon movement, often a precursor to osteoarthritis. Strain or injury to the knee joint can result in tears in the meniscus (cartilage) or patellofemoral pain syndrome—pressure build-up behind the kneecap. These conditions should be reviewed with a medical professional.
To ease the harmless but sometimes disconcerting creaks in the knees, here are six stretches you can do to loosen and strengthen muscles and connective tissue to reduce the sound effects.
