Runners Knee - Iliotibial Band Friction Syndrome

The most common injury for a runner is that of runners' knee which can also be known as iliotibial band friction syndrome. The knee is a complex joint and involves the tibia, femur and patella to work in unison. For many years the cause of runners' knee was thought to be caused by chondromalacia of the patella which is a softening of the cartilage of the knee cap; however it is also widely thought to be from the richly innervated subchondral bone, infrapatellar fat pad, or the medial and lateral retinaculum of the joint.
