Not uncommon amongst those training for a marathon, runner’s knee is the result of a thickening of the Ilio-tibial (band of tissue) on the outside of the leg where the quadriceps muscles sit. Running causes it to hit against the outside of the femur resulting in pain. The knee is also lifted from its normal running position and pain in the knee cap develops.
