What Could Cause Pain at the Front of the Knee When Going Down Stairs?

When you go down stairs, your knee joint gets a lot of pressure and the kneecap (patella) has to slide over the thigh bone (femur). If the muscles around your knee are weak or tight, the kneecap might not sit in the right spot. This misalignment, called maltracking, makes the cartilage under the kneecap get irritated. Over time, repeated stress from activities like descending stairs can make the pain worse. Other causes like an injury, overuse, or even changes from past knee surgery can also hurt the front of the knee. The pain you feel is a signal that something is off with how your knee joint is working. Even little issues like flat feet or uneven leg muscles can add extra stress during movements. Taking it easy, using ice, or doing specific exercises to boost knee strength may help, but it's important to get a proper examination from a doctor to know the exact reason for the pain.
