Iliotibial band syndrome
Iliotibial band syndrome is a condition when the tough cord of tissues, i.e., the Iliotibial band extending from the outside of your hip to the outer knee becomes so stiff that it starts rubbing against the outside of your femur bone. Cyclists and distant runners are particularly more susceptible to suffer from this mechanical knee problem.
Foot or hip pain
If a person is suffering from hip or foot pain, then might change their way of walking, but this altered walking way can put more strain on the knee joint thus leading to knee pain.
