What causes IT Band syndrome and how to fix it?

Iliotibial band pain, also known as IT band syndrome (ITBS), is one of the most common causes of knee pain—especially among individuals who participate in endurance sports. In fact, it accounts for up to 12% of running injuries and as much as 24% of cycling-related injuries.

Among the superficial connective tissues in the human body, the IT band is the tightest structure. It plays a crucial role in stabilizing the knee joint by counterbalancing the actions of the hip adductors and internal rotators.

However, with repetitive movement over time, the IT band can become progressively tighter and stiffer due to the accumulation of scar tissue and adhesions. These adhesions—particularly between the quadriceps and the IT band—can limit natural gliding motion during knee flexion and extension, ultimately leading to pain and reduced function.

Why do scar tissues and adhesions increase?

Every muscle gets bigger and stronger while healing from micro tears in the muscle fibers after continuous movement. In this process, if the waste product such as lactic acid is not dissolved into the blood stream with proper stretching or massage, the tissue creates tight and tender knots in the muscles. With these scar tissues and adhesion, muscle can not activate effectively with increased pain and stiffness.

Signs and Symptoms

1. Stabbing or stinging pain along the outside or inside of the knee
2. A feeling of the ITB “snapping” over the knee as it bends and straightens
3. Swelling near the outside or inside of your knee
4. Occasionally, tightness and pain at the outside of the hip
5. Continuous pain following activity, particularly with walking, climbing, or descending stairs

How IT band tightness can cause the knee pain?

The IT(iliotibial) band transmits tension between your hip, knee, and the upper portion of your lower leg. When it becomes overly tight and fails to glide smoothly alongside the quadriceps muscle, it can pull the patella (kneecap) and cause the lower leg to rotate outward. As a result of this abnormal tension, the patella may track slightly outside its normal groove, leading to pain on the outer or inner side of the knee.

What is the most effective way of releasing the IT Band?

The most important aspect in IT Band pain treatment is to decrease tension in ITB by releasing the scar tissue and adhesion. It requires strong external force to achieve this goal due to the nature of IT Band. General stretching has only slight releasing effect and it is not enough to break up the scar tissue. Moreover, we need to consider treatment in Gluteus Medius, Quadratus Lumborum, Tibialis anterior and peroneal muscles which is on the same fascial line (Lateral Fascia Line).

1. Extracorporeal shock wave therapy (ESWT)

By increasing circulation and breaking down scar tissue, shockwave therapy will stimulate cell regeneration and promote normal healing and rapid reduction of pain

2. Vibracurssor Therapy
High frequency Vibratory force can break up the scar tissue and adhesion with improving circulation. This can be applied by the medical professionals.

3. Trigger Point Therapy with elbow
This technique works amazingly well if the practitioner can pinpoint the trigger point and wait enough until release.

Put one towel on the IT Band and apply the your (practitioner) body weight gently over the tender spot.

Maintain proper amount of force on the spot (Muscle will be twitching if you pinpoint the right spot).

Wait until the tissue becomes softer and move to the next spot.

4. Foam roller stretching
Apply your body weight on the form roller. If you find a tender spot, stay there 30 seconds to 1 minutes and rub it again. Repeated several times in a day.

5. Trigger point release with a firm ball
This can be done as a self trigger point release method. Put your body weight on the firm ball (Lacrosse ball or Yoga tuneup ball). Find the tender spot and stay there for 30 secs to 1 minutes. Try several repetitions in one spot.

6. iliotibial Band stretching
ITB stretching is working better after breaking up the scar tissues, trigger points and adhesion with the above method.

How to prevent IT band pain?

After intensive exercise, it’s essential to stretch the IT band, use a foam roller, and perform regular self-trigger point release with a firm ball. In addition, strengthening the muscles around the ankles, knees, and hips can help improve endurance and reduce the risk of future injuries.

Don’t forget to stretch the muscles you’ve used during your workout. Without proper recovery, waste products such as lactic acid can build up in the tissue, leading to the gradual formation of scar tissue and painful trigger points.
