IT Band Syndrome is one of the most common causes of knee pain in runners. It is an overuse injury caused by repetitive friction of the iliotibial band across the Lateral Epicondyle (see image below). This syndrome presents as lateral (outside) knee pain due to tightness of the ITB and hip abductors. As a result of movement of the band during flexion and extension of the knee and hip, a tight band could be responsible for the inflammation at the knee or even the hip, or along the IT Band.
The main physical causes of this condition are:
- Tight IT Band.
- Altered foot function: Excessively flat feet cause the lower leg to internally rotate excessively, adding a stretch tension to the IT Band.
- Decreased Glute Medius/Maximus function.
- Overactive TFL muscle due to lack of Gluteus Medius function
- A weak or inactive Vastus Medials (VMO). This is the inside muscle group of the quadriceps and tends to become weak on people.
- Medial (inward) knee migration during walking/running.
- Leg length discrepancy.
- Tightness of hamstrings/Quads/Calves
Other non-biomechanical reasons for the condition can be improper running technique, worn-out or improper running shoes, hill running, canted running surfaces, and increasing mileage too fast. If you feel any of the non-biomechanical reasons may be an issue, please confer with your running store or coach.
If you are, or in the future, suffer from IT Band Syndrome, conservative treatment usually does a great job of freeing you from your pain. In our practice we utilize Active Release Technique (www.activerelease.com), Graston Technique (www.grastontechnique.com) and Kinesio Taping along with other modalities to treat the pain and prevent it from coming back. I recommend you familiarize yourself with the above techniques if you are a runner; they are the top conservative treatment methods running related over-use injuries.
Dr. Christie- I've been training for a half-ironman and my IT band has been causing me great pain while on the bike. I've spoken to Scott about it, but just wanted to thank you for this article post, even if it was posted a while ago.
