Patellofemoral pain syndrome (PFPS), also known as runner's knee, means that you have pain in front of the knee or around the kneecap (patella). This is where the knee connects with the lower end of the thighbone (femur).
Patellofemoral pain syndrome may be caused by a structural defect, or a certain way of walking or running. Other causes may include:
Malalignment of the kneecap
Excessive training or overuse
Injury or trauma
Weak thigh muscles
Tight hamstrings
Tight Achilles tendons
Poor foot support
Walking or running with the feet rolling in while the thigh muscles pull the kneecap outward
These are the most common symptoms of runner's knee:
Pain in and around the kneecap that happens when you are active.
Pain after sitting for a long time with the knees bent. This sometimes causes weakness or feelings of instability.
Rubbing, grinding, or clicking sound of the kneecap that you hear or feel when you bend and straighten your knee
Kneecap that is tender to the touch
The symptoms of runner's knee may look like other conditions and health problems. Always talk with your healthcare provider for a diagnosis.
Your healthcare provider can diagnose PFPS knee by looking at your health history and doing a physical exam. X-rays may be needed for evaluation of the knee.
Treatment will depend on your symptoms, age, and general health. It will also depend on how bad the condition is.
The best course of treatment is to stop running until you can run again without pain. Treatment is aimed at relieving pain and increasing strength and range of motion. Treatments may include:
Strengthening exercises
Stretching exercises
Cold packs
Elevating the leg
Compression knee wrap
Medicines, such as ibuprofen
Shoe inserts (orthotics)
Knee bracing
Patellofemoral taping
Preventing PFPS includes not overstressing your knees. You can do this by:
Maintaining a healthy body weight
Warming up before physical activity
Stretching before and after physical activity
Increasing your activities gradually
Wearing shoes appropriate for your physical activities
Running leaning forward with your knees bent
