well that's hard to say. the answer could depend on many factors including your age and whether or not you've had any knee injuries. in general it's not unusual for our knees to squeak pop creak and crackle when we walk or squat down. these sounds can be caused by a variety of things including simple wear-and-tear to the cartilage within the knee joint or osteoarthritis. as long as the squeaking isn't accompanied by pain the sound probably doesn't mean anything. if you start to have pain associated with your noisy knees then it would be a good idea to get it checked out. you can help keep your knees healthy by following these prevention tips. as always if you're concerned about whether or not there's something wrong with your knees don't hesitate to make an appointment with your primary care provider. good luck!
