Lateral knee pain whilst running? Is it ITB Friction Syndrome?
IT Band Syndrome Causes. Iliotibial band syndrome is caused by excessive friction of the iliotibial band and the underlying bursa due to repetitive knee-bending activities. This is an overuse injury, although direct trauma to the outer knee may cause the bursa to get inflamed.
Iliotibial band syndrome (ITBS) is the result of inflammation. and irritation of the distal portion of the iliotibial tendon (see illustration) as it rubs against the bursa that lies underneath the tendon and lateral femoral condyle (outer part of the thigh bone at the knee), or less commonly, the greater tuberosity.
The iliotibial band, or IT band, is a thick band of connective tissue that runs from the hip to the top of the shin. The portion of this ligament that extends down the side of the knee can become tightened due to repetitive, high-impact activity. As the band tightens, friction between the IT band and the outside of the knee can cause serious.
The iliotibial band (ITB) is a thick band of tissue that extends down the lateral side of the leg from the thigh down over the knee and attaches to the tibia. When the knee flexes and extends, the ITB slides over the bony parts of the outside of the knee.Mechanism of InjuryFriction occurs when the knee bends during running in soccer and the tendon moves back and forth across.
Picture of the iliotibial (IT) band Iliotibial band syndrome (ITBS or IT band syndrome) is an overuse injury of the connective tissues that are located on the lateral or outer part of thigh and knee. It causes pain and tenderness in those areas, especially just above the knee joint.
Iliotibial band syndrome, or IT band syndrome, is a painful condition that results from excessive tightness or inflammation in the IT band. It is a very common injury for runners to receive, and the pain is usually located around the knees.
The iliotibial band moves forward and backward relative to the axis of rotation of the knee and is thus prone to friction over the lateral epicondyle on the outer aspect of the knee. There is a bursa that lies between the ITB and the epicondyle which often becomes inflamed in these friction syndromes.
