Patellofemoral pain can be thought of where pain is present in and surrounding the tissues between the patella and the femur. The cause of the pain can be something of a mystery as it rarely develops quickly and isn’t the result of a traumatic incident the way a ligament tear is. The symptoms are often made worse by, though not exclusively, activities like squatting, lunging, kneeling, going down stairs or running downhill. In-other words relatively high load activities that put a lot of stress on or through the area. in addition to this sitting for long periods where the knee is flexed can also cause the symptoms to get worse.
