Doctors aren't certain what actually causes patellofemoral pain syndrome, but it's been associated with:

  • Overuse. Repetitive stress on your knee joint — such as that sustained during running or jumping sports — may result in patellofemoral pain.
  • Poor control of your muscles. Patellofemoral pain can occur when the muscles around your hip and knee don't function well to maintain proper tracking of your kneecap.
  • Injury. Trauma to the kneecap, such as a dislocation or fracture, has been linked to patellofemoral pain syndrome.
