There are many knee pains and injuries that can be very painful. One of these is called Iliotibial Band Syndrome (or IT Band Syndrome). It can be a frustrating and debilitating injury that effects the knee and hip.
IT Band Syndrome is an example of an injury that generally occurs over time, not like an acute back spasm or ankle sprain. It usually starts as a nagging injury, or nuisance feeling and quickly progresses into something that can take even the most elite and highly trained athlete out of all sports. It is very common in runners and cyclists.
What is Iliotibial Band Syndrome?

Iliotibial band site of inflammation
The iliotibial band is really a long, flat tendon that is an extension of a muscle called the Tensor Facia Lata (TFL). Two other muscles that insert into the top portion of the IT band are the Gluteus Maximus and Gluteus Medius (yep, your big butt muscles!). It runs from a bone called the Ilium, or pelvis, down the outside of your leg and attaches to the knee at the tibia (and blends with one of the quadriceps muscles called the Vastus Lateralis at Gurdy’s Tubercle).
The TFL muscle is responsible for hip flexion and abduction (lifting your leg to the side without rotation). The Gluteus Maximus and Medius muscles also play an important roll in hip abduction.
The main problem happens when the tensor facia lata muscle and IT band become tight. This causes the tendon to pull the knee out of alignment and rub on the outside of the joint. The rubbing causes irritation and swelling of the tendon, leading to a frustrating pain that seems to never go away.
What causes Iliotibial Band Syndrome?
IT band syndrome can occur because of functional (biomechanical) issues or overworked muscles.
Functional issues include things like:
- one leg being shorter than the other
- pronation (rolling) of the foot
- muscle imbalances (weak gluteal muscles) due to other injury or birth
- flat feet
Overworked muscles can happen by:
- running on concave surfaces, which actually causes one leg to become shorter for a prolonged period of time
- weak gluteus muscles, causing the tensor facia lata muscle to overwork and pull the IT band tight
- increasing exercise intensity or duration too quickly
- improperly fit bicycle or running shoes
- excessive circular track running (strengthening the inside leg due to the angle of the body)
What to do about Iliotibial Band Syndrome?
First, be sure to remove or reduce the cause of the problem, be it an overuse or functional problem. This may include:
- stopping or reducing activities
- purchasing new equipment
- changing your workout – consider water and non-weight baring activities
- side stretching (see below)
- strengthening the gluteal muscles
- seeking professional medical attention or sports injury education
From there, the immediate treatment is basically the same as for any injury – rest, ice, compression and elevation for 48 to 72 hours.
Then you MUST look for ongoing treatment and prevention or the injury will reoccur and could progress into a debilitating chronic condition.
Ongoing treatment may include:
- Positional release therapy (to release the tight hip muscles)
- Deep tissue massage for the hip, back, leg and thighs
- Instruction in proper and thorough warm up and cool down techniques to increase oxygen to the muscles
- Instruction in proper stretching techniques – you can injure yourself further with overstretching! Make sure you consult a professional trained in sports specific stretching
Side Stretch
This is one of the best stretches for the tensor fascia lata, side of the leg and back.
- Stand upright and cross one foot behind the other.
- Then lean sideways towards the foot that is behind the other. Try NOT to rotate your body.
- Hold this stretch for about 15 to 20 seconds, and then repeat it 3 to 4 times on each leg.
