Many people face the problem of knees cracking and popping. When you stand up, you may experience your knee cracking, and then you walk downstairs and your knee pops. Why is that?

"Often it's just the fluid that coats your joints being pushed through certain ranges of motion—and is totally benign," explains Benjamin Butts, director of rehabilitation services and performance therapy at Providence Saint John's Health Center in Santa Monica. However, there are times when people experience constant cracking coupled with consistent pain. That means t something is wrong.

Generally, tight or misaligned muscles will pull the knee cap out of alignment, explains David Reavy, director of React Physical Therapy in Chicago. Over time that imbalance can cause clicking or popping, which could be a potential problem, says Butts, "because the cartilage can become worn down and potentially lead to early onset arthritis, as well as many issues involved with deterioration of the joint."
