Why does my knee make a crunching sound?
It’s not unusual to hear cracks, pops, or crunches from knees, especially when getting up from a chair, walking downstairs, or getting out of the car. The noise we hear is called crepitus, and can happen at any joint; but the knees, ankles, and fingers are most common. The crunching noise can also sometimes be felt by putting your hand over your knee. Knee crepitus can happen at any age, yet it does become more frequent as we age. Understanding what it is and how to recognize is beneficial so you know what to do when it happens to you.
