Patellofemoral Pain Syndrome (PFPS), often referred to as “runner’s knee,” is a common condition characterized by pain around or behind the kneecap (patella), typically where the patella meets the thigh bone (femur). The pain is often aggravated by activities that involve bending the knee, such as squatting, climbing stairs, running, or sitting for extended periods
Whether you are trying to push yourself to run farther or are training for an upcoming race, you may notice an onset of knee pain as you increase your weekly mileage. This pain, often over or around the patella, can limit how far you are able to run for days or weeks at a time.
