Anyone know why a persons knees crack? We moved into a house with stairs in November and my knees STILL crack every single time I walk upstairs. I am in my 30's, work out and am only slightly over weight. Other than having my 2 kids 15mo apart, I can't imagine what could cause it. They don't hurt, just sound like rice crispies.
