Patellofemoral Pain Syndrome
Signs and Symptoms
The most common symptom of patellofemoral pain syndrome is a dull ache under the kneecap while walking down stairs, squatting or getting up after sitting for a long time. In addition, your knee may catch when bending, and you may experience a painful grating or creaking sensation.
Although many physically active people notice symptoms when starting a new activity or increasing their level of intensity, people who don’t exercise may also experience patellofemoral pain simply doing their daily activities.
