The two most common conditions we see in runners are Patello-Femoral Pain Syndrome (PFPS) and Iliotibial Band (ITB) Friction syndrome. There are a few biomechanical issues that can predispose people to knee pain however there are also a lot of external factors that can contribute and can easily be tweaked to decrease the risks of developing knee pain.
Patello-Femoral Pain is pain that affects the joint formed between the patella (knee cap) and bottom of the thigh bone (femur). This presentation of knee pain is more commonly seen in women, and is not only limited to runners. It is frequently seen though in the younger population of recreational runners.
Symptoms of PFPS include:
Things that contribute fall in to a few categories:
Iliotibial Band Syndrome
The ITB is a thick band of connective tissue that runs from your hip, down the outside of your leg to just below your knee. The pain is caused by the friction created as the ITB moves posteriorly during knee flexion. It occurs near or just after foot strike when running. Downhill running reduces the angle of knee flexion and can aggravate the ITB. The pain will generally flare up at a certain distance on the outside of the knee. It will then feel better after a run but will return again once running is commenced.
