Patello-femoral Pain Syndrome

This is a generic term used to describe pain over the front of the knee cap. Muscular imbalances in the thigh cause the patella (knee cap) to move out of its normal position in a groove on the femur (thigh bone) and rub against structures such as cartilage, which can cause damage to them and pain to the patient.


  • Aching around the borders of the knee cap
  • Pain sitting for prolonged periods
  • Clicking of the knee when it is flexed (bent)
  • Tight muscles in the legs; quadriceps, hamstrings, calf.
