What is Runner’s Knee?

Runner’s knee, medically termed Patellofemoral Pain Syndrome or Chondromalacia Patella, is a common condition that causes knee pain around or deep to the kneecap. It is an overuse injury due to repetitive stress that occurs in the joint between the kneecap and the thigh bone. This condition can occur at any age but frequently affects the younger population, especially females or active individuals who run, jump or perform squats frequently. If left untreated, this condition can potentially result in knee osteoarthritis.

What is Runner's Knee or Patellofemoral Pain Syndrome?

Causes of Runner's Knee

Runner’s knee occurs when there is increased pressure on the kneecap (patella) against the thighbone (femur). The increased pressure causes the kneecap to grind against the thighbone and creates damage to the articular cartilage.  This leads to pain and inflammation within the patellofemoral joint. The increase in pressure is due to several risk factors.
