The iliotibial band (ITB) is a thick band of fascia that runs down the outer thigh from the hip to the knee. It is made up of mostly collagen fibres, the strongest protein found in nature, and a small amount of elastin fibres, which make it slightly elastic. While the ITB is not a muscle, it connects the muscles around the hip and knee, and is essential for the movement of the hip, thigh, and knee. ITB syndrome, or iliotibial band syndrome, is a common injury, particularly among runners, caused by the overuse of the ITB. It causes sharp pain and swelling around the knee.

What You'll Learn
Iliotibial band syndrome (ITBS)
ITBS is an overuse injury caused by the repeated compression of the outside of the knee or swelling of the fat pad between the bone and the tendon on the side of the knee. It can also be caused by a sudden increase in activity levels, poor physical condition, lack of warm-up, or drastic changes in activity levels. The syndrome causes sharp pain in the knee and hip region, and the pain worsens with exercise. Other symptoms include grating sounds or feelings when the knee or hip moves, pain in the greater trochanter or lateral epicondyle, and increased pain when going downhill.
ITBS can be diagnosed by a healthcare provider based on an individual's history of exercise and symptoms, and a physical examination may be performed to check for specific signs of ITBS. Treatment options include rest, physical therapy, medications, and, in rare cases, surgery. About 50-90% of people with ITBS improve within four to eight weeks of nonsurgical treatment, and it is recommended to discuss treatment options with a healthcare provider.
To reduce the risk of developing ITBS, it is advisable to avoid running on slanted surfaces, ensure proper technique during activities, gradually increase training intensity, properly warm up and cool down, and wear supportive shoes.

ITB anatomy and composition
The iliotibial band (ITB) is a thick band of fascia formed proximally at the hip by the fascia of the gluteus maximus, gluteus medius and tensor fasciae latae muscles. It is a longitudinal fibrous reinforcement of the fascia lata. The gluteus maximus and tensor fasciae latae connect to the ITB via an aponeurosis. The fascia lata is a fascial sheath enveloping the thigh, and its fibres contribute to the ITB.
The ITB is a type of connective tissue that lacks contractile properties, meaning it cannot cause any direct muscle contractions. It runs along the lateral thigh and serves as an important structure involved in lower extremity motion. The ITB assists the TFL muscle and gluteus maximus muscle in their action of causing hip abduction. The ITB shares the innervation of the TFL and gluteus maximus via the superior gluteal nerve and inferior gluteal nerve.
The ITB is composed of mostly collagen fibres, which are aligned in a very organised, vertical fashion. This allows for better force absorption with weight-bearing activities. There is also a small amount of elastin fibres among the layers of collagen, which allow the ITB to be slightly elastic and pliable, helping it to act as a spring.
The ITB contributes to lateral knee stabilization. During knee extension, the ITB moves anterior to the lateral condyle of the femur, while at around 30 degrees of knee flexion, the ITB moves posterior to the lateral condyle. The ITB originates at the anterolateral iliac tubercle portion of the external lip of the iliac crest and inserts at the lateral condyle of the tibia at Gerdy's tubercle.

ITB functions
The iliotibial band (ITB) is a thick band of fascia formed proximally at the hip by the fascia of the gluteus maximus, gluteus medius, and tensor fasciae latae muscles. The ITB is also sometimes known as Maissiat's band.
The primary function of the ITB is to stabilize the hip and knee, though it also supports movements of the hip and knee through the action of the gluteus maximus and tensor fasciae latae muscles. The muscles associated with the ITB flex, extend, abduct, and laterally and medially rotate the hip. The ITB also contributes to lateral knee stabilization. During knee extension, the ITB moves anterior to the lateral condyle of the femur, while at around 30 degrees of knee flexion, the ITB moves posterior to the lateral condyle.
The ITB is an extension of the tendinous insertions of the gluteus maximus and other muscles. The gluteus maximus primarily serves to extend the hip, but it also contributes to hip abduction via the ITB tract. The ITB shares innervation with the TFL and gluteus maximus via the superior gluteal nerve and inferior gluteal nerve.
The ITB is involved in lower extremity motion and is used constantly during walking and running. It is of critical importance to asymmetrical standing (pelvic slouch). The upward pull on the lower attachment of the ITB thrusts the knee back into hyperextension, thereby locking the knee and converting the limb into a rigid supportive pillar.
Iliotibial band syndrome (ITBS) is a common injury associated with the ITB. It is a non-traumatic overuse injury that can be caused by running, cycling, hiking, or other physical activities. ITBS occurs when the iliotibial band becomes irritated or swollen from rubbing against the hip or knee bones, causing sharp pain. Treatment for ITBS typically involves rest, physical therapy, and medication, though surgery may be recommended in rare cases if other treatments are ineffective.

ITBS causes
The iliotibial band (ITB) is a thick band of fascia formed proximally at the hip by the fascia of the gluteus maximus, gluteus medius, and tensor fasciae latae muscles. ITBS, or iliotibial band syndrome (ITBS), is a common injury that causes pain on the outside of the knee. It is often associated with running, but can also be caused by cycling or hiking. ITBS is considered an overuse injury, typically affecting athletes who have suddenly increased their level of activity.
ITBS occurs when the iliotibial band becomes irritated or swollen from rubbing against the hip or knee bones. This can cause inflammation in the bone, tendons, and small, fluid-filled sacs in the area, resulting in pain. The pain typically starts after exercise and worsens as the syndrome progresses, eventually persisting even during rest. The pain may also spread up the thigh to the hip. Other symptoms include grating sounds or feelings when the knee or hip moves, pain over the greater trochanter in one or both hips, and pain that worsens when going downhill.
ITBS is commonly seen in runners, especially long-distance runners, and those new to exercise. Athletes in sports such as cycling, skiing, rowing, soccer, basketball, and field hockey may also experience ITBS. Experts note that ITBS often affects US Marines during training, with more than 20% developing the condition. Additionally, ITBS is more prevalent in females than males.
There are several risk factors that increase the likelihood of developing ITBS. These include bowed legs, having one leg longer than the other, knee arthritis, rotating the ankle, leg, or foot inward when moving, and weakness in the hip, butt, or abdominal muscles. Training on tilted surfaces, such as downhill running or always running in the same direction on a track, can also lead to repetitive stress on the IT band. A sudden increase in training volume or intensity can further contribute to increased stress and faulty movement patterns.

ITBS treatments
ITBS, or Iliotibial Band Syndrome, is a common injury, especially among runners, caused by the iliotibial band getting irritated or swollen from rubbing against hip or knee bones. It can be treated with rest, physical therapy, and medication. Surgery is rarely required.
Rest
ITBS is often caused by overuse, so rest is an important part of treatment. This may involve taking a break from sports or other activities that cause pain.
Physical Therapy
Special exercises can help to stretch and strengthen the muscles around the hip and knee, reducing pain and improving function. Working with a physical therapist can be helpful.
Medication
Pain medicines, such as ibuprofen or other anti-inflammatories, can help to reduce pain and inflammation associated with ITBS.
Ice
Applying ice to the affected area may help to reduce pain and inflammation.
Activity Modifications
Making modifications to activities that cause pain can help manage ITBS. For example, lowering the bicycle seat when cycling, improving running form, or avoiding running downhill or on slanted surfaces.
Surgery
In rare cases, if other treatments are ineffective, surgery may be recommended to remove the part of the iliotibial band that moves over the femur.
