Patellofemoral Pain Syndrome
Signs and Symptoms
The most common symptom of patellofemoral pain syndrome is a dull ache underneath the kneecap while walking down stairs, squatting or getting up after sitting for long periods of time. In addition, your knee may catch when bending, and you may experience a painful grating or creaking sensation.
Although many active people notice symptoms when starting new activities or increasing their level of intensity, especially with respect to high-impact sports, non-active people can suffer patellofemoral pain during routine daily activities as well.
