Patellofemoral pain syndrome usually causes a dull, aching pain in the front of your knee. This pain can be aggravated when you:

  • Walk up or down stairs
  • Kneel or squat
  • Sit with a bent knee for long periods of time

When to see your doctor

If the knee pain doesn't improve within a few days, consult your doctor.
