What are the symptoms of patellofemoral pain syndrome?

The main symptoms of patellofemoral pain syndrome are:

  • Pain
    You may feel pain in the front of your knee and around and behind your kneecap. It can sometimes be quite severe and everyday movements like walking up and down stairs can make it worse. You may also feel a dull ache, for example after you’ve been sitting for a long time. The pain often makes it difficult to kneel or squat. It’s often aggravated by running, so it frequently occurs during or after you’ve played sport.
  • Crepitus
    Changes in the surface of your cartilage can cause a scratching or grating sensation from the kneecap, which you may be able to hear when you bend or straighten your knee. Crepitus doesn’t often cause pain.

The effect of these symptoms on your everyday life can vary from time to time.
