What Causes Anterior Knee Pain?

Anterior knee pain often occurs when the under surface of the kneecap comes in contact with the thigh bone. It is usually caused by softening and breaking down of the of the joint surface (cartilage) underneath the kneecap.

This causes swelling and pain as the knee bends and straightens and is particularly noticeable when the kneecap is under increased strain such as climbing or descending stairs, kneeling and squatting. The following may increase the likelihood of Anterior Knee Pain

  • Abnormal knee cap positioning
  • Tightness or weakness of the muscles associated with the knee
  • Too much activity involving the knee
  • Flat feet
  • Being overweight
  • Previous injuries related to the kneecap
  • Runners, football players, cyclists, and other people who exercise often
