Iliotibial
Band Syndrome

Definition
Iliotibial Band Syndrome is one of the leading causes of lateral knee
pain in runners. The iliotibial band is a superficial thickening of
tissue on the outside of the thigh, extending from the outside of the
pelvis, over the hip and knee, and inserting just below the knee. The
band is crucial to stabilizing the knee during running, moving from
behind the femur to the front of it during the gait cycle. The continual
rubbing of the band over the bone, combined with the repeated flexion
and extension of the knee during running may cause the area to become
inflamed or the band itself may become irritated.
Symptoms
The symptoms range from a stinging sensation just above the knee joint
on the outside of the knee or along the entire length of the iliotibial
band to swelling to a thickening of the tissue at the point where the
band moves over the femur. The pain may not occur immediately, but will
worsen during activity when the foot strikes the ground if you overstride
or run downhill, and may persist afterward. A single workout of excessive
distance or a rapid increase in weekly mileage can aggravate the condition.
Causes of Injury
Iliotibial Band Syndrome is the result of both poor training habits
and anatomical abnormalities.
· Running on a banked surface, such as the shoulder of a road
or an indoor track, causes the downhill leg to bend slightly inward
and causes extreme stretching of the band against the femur.
· Inadequate warm-up or cool-down.
· Running excessive distances or increasing mileage too quickly
can aggravate or cause injury.
· Anatomical abnormalities such as bowlegs or tightness about
the iliotibial band.
Short Term Treatment
To treat functional problems resulting from poor training:
· Decrease mileage.
· Ice knee after activity.
· Alternate running direction on a pitched surface.
· Foot orthoses and shoe changes
· Stretching to tolerance.
Long Term Treatment
To treat structural abnormalities such as a natural tightness in the
band:
· Stretching, especially before working out, to make the band
more flexible and less susceptible to injury.
· In extreme cases, surgery to relieve tightness in the band.
Both structural and functional problems need to be considered when treating
Iliotibial Band Syndrome.
