The iliotibial band (ITB) is a thick band of fascia that runs along the outside of the leg, connecting the pelvic bone to the knee. It is a tendon, made up of collagen fibres, which allows for better force absorption during weight-bearing activities. The ITB is not a muscle, but it is involved in lower extremity motion and helps to stabilise the pelvis during locomotion. ITB syndrome is a common injury, particularly among runners, caused by the ITB becoming irritated or swollen from rubbing against the hip or knee bones.

The iliotibial band (ITB) is a tendon that runs along the outside of the leg from the top of the pelvic bone to below the knee
The iliotibial band (ITB) is a tendon that runs along the outside of the leg, from the top of the pelvic bone to just below the knee. It 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 made up mostly of collagen fibres, with a small amount of elastin fibres among the collagen layers, which give it some elasticity and pliability.
The ITB serves several important functions, including pelvic stabilisation and posture control. It also plays a critical role in asymmetrical standing (pelvic slouch) and helps to stabilise the pelvis during locomotion. The ITB is involved in lower extremity motion, assisting in the flexion, extension, abduction, and lateral and medial rotation of the hip. It also contributes to lateral knee stability, particularly during knee extension and partial flexion, making it essential for activities like walking and running.
Iliotibial band syndrome (ITBS) is a common injury associated with the ITB. It occurs when the ITB becomes irritated or swollen from rubbing against the hip or knee bones during activities such as running, cycling, or hiking. This friction causes pain and inflammation, which can worsen over time if left untreated. Treatment for ITBS typically includes rest, physical therapy, and medication, although surgery may be recommended in rare cases if other treatments are ineffective.
ITBS is often associated with overuse or a sudden increase in activity levels. It is prevalent among long-distance runners, cyclists, and hikers, and is characterised by sharp, burning, or aching pain that worsens with exercise. The pain may be felt on the outside of the knee or hip and can increase when running downhill or sitting for long periods with the knee bent.

The ITB is made up of collagen fibres, which are aligned vertically to better absorb force during weight-bearing activities
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 tendon that runs along the outside of the leg, connecting from the top of the pelvic bone to just below the knee. The ITB is made up of collagen fibres, which are aligned vertically to better absorb force during weight-bearing activities. Collagen is the strongest protein found in nature. The collagen fibres are arranged in a highly organised, vertical manner, allowing for optimal force absorption during weight-bearing activities. This unique structure enables the ITB to effectively stabilise the pelvis and control posture during locomotion.
The ITB plays a crucial role in lower extremity motion and lateral knee stabilisation. It traverses superficial to the vastus lateralis and inserts on the Gerdy tubercle of the lateral tibial plateau, with partial insertion on the supracondylar ridge of the lateral femur. This anatomical arrangement contributes to the stability of the knee during extension and partial flexion, making it essential for activities such as walking and running.
The ITB is susceptible to a common condition known as iliotibial band syndrome (ITBS) or iliotibial band friction syndrome (ITBFS). ITBS is characterised by irritation, swelling, and pain in the ITB due to repeated compression or friction against the hip or knee bones during physical activities. It is often associated with running, cycling, and other intense physical activities, particularly when there is a sudden increase in activity levels. ITBS can cause sharp, burning, and aching pain that worsens with exercise and can lead to chronic inflammation.
To diagnose ITBS, healthcare providers consider the patient's history of exercise and symptoms and perform a physical examination. They may also recommend imaging tests to confirm the diagnosis. Treatment options typically include rest, physical therapy, and medications, with surgery being a last resort if other treatments prove ineffective. Preventative measures, such as modifying activities and gradually increasing intensity, can help reduce the risk of developing ITBS.
In summary, the ITB is a crucial anatomical structure for lower extremity motion and posture control. Its unique composition of vertically aligned collagen fibres enables effective force absorption during weight-bearing activities. However, the ITB is also susceptible to ITBS, a common condition affecting physically active individuals, particularly runners and cyclists. Understanding the structure and function of the ITB is essential for preventing and managing ITBS, ensuring optimal lower extremity function and overall well-being.

The ITB is involved in lower extremity motion and is important for pelvic stabilisation and posture control
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 tendon, a thick elastic tissue that connects muscle to bone. The ITB is not a muscle, but it is involved in lower extremity motion and is important for pelvic stabilisation and posture control.
The ITB runs along the lateral thigh and is involved in lower extremity motion. It serves as an important structure for pelvic stabilisation and posture control. 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. The ITB contributes to lateral knee stability and is used constantly during walking and running. When a person is leaning forward with a slightly flexed knee, the ITB provides the knee's main support against gravity.
The ITB is associated with several muscles, including the tensor fasciae latae and some fibres of the gluteus maximus. These muscles flex, extend, abduct, and laterally and medially rotate the hip. The ITB also shares the innervation of the tensor fasciae latae and gluteus maximus via the superior gluteal nerve and inferior gluteal nerve. The ITB's function is influenced by these muscles, which act through it to produce movements of the thigh.
The ITB is susceptible to iliotibial band syndrome (ITBS), a common injury caused by the ITB becoming irritated or swollen from rubbing against the hip or knee bones during activities such as running, cycling, or hiking. ITBS is characterised by sharp, aching, or burning pain that worsens with exercise. Treatment for ITBS includes rest, physical therapy, and medication, with surgery being a last resort if other treatments are ineffective.

Iliotibial band syndrome (ITBS) is a common injury, especially in runners and cyclists, caused by the ITB rubbing against the hip or knee bones
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 made up of mostly collagen fibres, with a small amount of elastin fibres among the layers of collagen, which allow it to be slightly elastic and pliable. The ITB is not a muscle, but it is a tendinous structure that derives from the mesoderm, the middle layer of the embryologic trilaminar disc of tissue that forms due to gastrulation in a fetus.
Iliotibial band syndrome (ITBS) is a common injury, especially among runners and cyclists, caused by the ITB rubbing against the hip or knee bones. This friction leads to inflammation and causes sharp pain or a burning sensation on the outside of the knee, which may spread up or down the leg. The pain is typically worse when running or cycling for longer durations or downhill. ITBS is an overuse injury that tends to worsen with repeated movement. It is often concomitant with underlying weakness in the hip abductor muscles, butt muscles, or abdominal muscles.
ITBS is one of the most common injuries in runners, with an incidence estimated between 5% and 14%. It is responsible for about 12% of running injuries and is more prevalent in females than males. ITBS is also observed in other sports involving repeated knee flexion and extension, such as hockey and football.
The diagnosis of ITBS is made by a sports medicine professional, such as a physiotherapist or sports doctor, based on the patient's history of exercise, symptoms, and a physical examination. Treatment options include rest, physical therapy, and medications such as non-steroidal anti-inflammatory drugs (NSAIDs) to manage pain and reduce inflammation. Surgery is rarely required and is typically a last resort when other treatments have proven unsuccessful.
To prevent ITBS, athletes can modify their training techniques, such as avoiding running on slanted surfaces, ensuring proper technique, and gradually increasing training intensity.

ITBS is characterised by sharp, aching or burning pain that gets worse with exercise and can be treated with rest, physical therapy and medication
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. ITB syndrome (ITBS) is a common injury, especially among runners, skiers, cyclists, and other athletes. It is considered a non-traumatic overuse injury and is often concomitant with underlying weakness of hip abductor muscles.
ITBS is characterised by sharp, aching, or burning pain. The pain worsens with exercise, particularly downhill movement, and can be felt around the kneecap, hip, or knee. The pain can also increase when moving the hip away from the body while supporting the knee. ITBS can sometimes cause patellofemoral pain syndrome (PFPS), leading to pain around and under the kneecap.
Treatment for ITBS typically involves rest, physical therapy, and medication. Physical therapy may include posture training, strengthening exercises for the glutes and hip abductors, and learning how to properly warm up and cool down before and after exercise. Steroid injections of corticosteroids may also be used to reduce inflammation. Surgery is rarely required for ITBS and is generally only recommended if other treatments have been unsuccessful.
To prevent ITBS, athletes can modify their activities by avoiding hills or slanted surfaces, ensuring proper technique, and gradually increasing training intensity. Wearing supportive shoes and warming up and cooling down slowly can also help reduce the risk of ITBS.
