Understanding Iliotibial Band Syndrome
The iliotibial band (ITB) is a thick band of fascia that originates at the iliac crest and inserts at the Gerdy tubercle on the lateral aspect of the proximal tibia. It is composed of dense fibrous connective tissue and serves as a ligament between the lateral femoral condyle and the lateral tibia to stabilize the knee. The ITB assists in hip abduction, internal rotation of the hip when the hip is flexed to 30°, knee extension when the knee is in less than 30° of flexion, and knee flexion when the knee is in greater than 30° of flexion.
What is the IT band?
The ITB is the distal fascial continuation of the tensor fascia lata, gluteus medius, and gluteus maximus. It traverses superficial to the vastus lateralis and inserts on the Gerdy tubercle of the lateral tibial plateau and partially to the supracondylar ridge of the lateral femur. There is also an anterior extension called the iliopatellar band that connects the lateral patella and prevents medial translation of the patella. The ITB is not attached to bone as it courses between the Gerdy tubercle and the lateral femoral epicondyle. This lack of attachment allows it to move anteriorly and posteriorly with knee flexion and extension. Some authors hypothesize that this movement may cause the ITB to rub against the lateral femoral condyle, causing inflammation. Other investigators hypothesize that injury of the ITB results from compression of the band against a layer of innervated fat between the ITB and epicondyle.

Causes of ITBS
The etiology of ITBS is controversial and likely multifactorial. One theory advocates that repetitive friction of the ITB and the lateral epicondyle during flexion and extension lead to inflammation of the contact area of the ITB. Contact between the ITB and lateral epicondyle occurs at 30° of flexion, which is the degree of knee flexion at foot strike. This contact area has the name of the “impingement zone.” However, anatomical studies have not supported this gliding motion across the lateral epicondyle. Histologic examinations of cadaveric specimens show a highly innervated fat pad that is deep to the distal ITB. Compression of this fat pad is implicated to be the source of the lateral knee pain. Furthermore, another theory includes chronic inflammation of a fluid-filled ITB bursa located between the ITB and lateral epicondyle. It is not clear at this time if one theory is most causative of the syndrome or if it is multifactorial.
Modifiable risk factors for iliotibial band syndrome include running on a tilted surface, hill running, errors in training technique, and abrupt changes in training intensity. Anatomical factors such as internal tibial torsion, hip abductor weakness, excessive foot pronation, and medial compartment arthritis leading to genu varum can increase the tension of the ITB and can perpetuate the pathology. ITBS correlates with greater trochanteric pain syndrome because of the altered biomechanics of the hip and tension of the proximal fascial complex. Also, patellofemoral syndrome is commonly seen in these patients because of the tension through the iliopatellar band.
Common symptoms
Iliotibial band syndrome often presents with lateral knee pain localized to the area between the Gerdy tubercle and the lateral epicondyle. The history is commonly consistent with a recent change in prolonged aerobic activities and rarely in the setting of an acute injury. The pain initially will occur at the completion of the activity but may be present at the beginning of the activity and even at rest with later disease progression. Furthermore, the pain is often worse with running on a cambered surface, and also hills or longer strides may increase symptoms as deeper knee flexion at foot strike leads to more time in the “impingement zone.”
Diagnosis and Treatment
How ITBS is diagnosed
Diagnosing iliotibial band syndrome typically involves a thorough physical examination and evaluation of the patient’s medical history. The healthcare provider will assess the area of pain, particularly the outer part of the knee, and check for tenderness, swelling, or tightness in the iliotibial band. They may also perform specific tests, such as the Noble compression test or the Ober test, to evaluate the tightness of the ITB and reproduce the symptoms.
In some cases, imaging tests like MRI or ultrasound may be used to rule out other potential causes of lateral knee pain, such as a meniscal tear or lateral compartment osteoarthritis. MRI can reveal thickening of the iliotibial band and inflammation of the surrounding tissues, while ultrasound can show thickening of the ITB and help guide corticosteroid injections for treatment.
Conservative treatment options
The primary approach to treating iliotibial band syndrome is conservative management, which aims to reduce pain and inflammation while addressing the underlying causes of the condition. Rest is crucial to allow the irritated tissues to heal, and patients should temporarily modify or stop activities that exacerbate their symptoms. Ice application and nonsteroidal anti-inflammatory drugs (NSAIDs) can help alleviate pain and reduce inflammation in the acute phase.
Physical therapy plays a key role in the treatment of ITBS. A physical therapist will develop an individualized program that focuses on stretching the iliotibial band and surrounding muscles, particularly the tensor fascia lata and gluteal muscles. Strengthening exercises for the hip abductors, extensors, and external rotators are also important to address muscle imbalances and improve stability. Soft tissue mobilization techniques, such as foam rolling or massage, can help release tension in the ITB and promote healing.
In addition to physical therapy, other conservative treatment options include:
- Modifying running or cycling technique to reduce stress on the ITB
- Using orthotics or shoe inserts to correct foot pronation and improve alignment
- Applying kinesiology tape to support the ITB and surrounding muscles
- Receiving corticosteroid injections to reduce inflammation in persistent cases

When to consider surgery
Surgical intervention for iliotibial band syndrome is rarely necessary and is typically considered only when conservative treatment options have failed to provide relief after several months. If a patient continues to experience significant pain and functional limitations despite consistent adherence to a comprehensive conservative management plan, surgery may be an option.
The most common surgical procedure for ITBS is an iliotibial band release, which involves cutting or lengthening the tight portion of the ITB to reduce tension and friction over the lateral femoral condyle. This can be performed through an open incision or arthroscopically. In some cases, bursectomy may also be performed to remove an inflamed bursa underneath the ITB.
It is essential for patients to have realistic expectations about surgical outcomes and understand that postoperative rehabilitation is crucial for a successful recovery. The decision to proceed with surgery should be made in close consultation with an orthopedic surgeon who specializes in knee conditions and has experience treating iliotibial band syndrome.
Effective Stretches and Exercises
IT band stretches
Stretching the muscles surrounding the IT band is crucial for alleviating tightness and preventing iliotibial band syndrome. One effective stretch is the standing IT band stretch. To perform this, stand with your feet shoulder-width apart and cross your left foot behind your right. Lean your upper body to the right while keeping your left foot planted, holding for 15-30 seconds before switching sides. Another beneficial stretch is the seated IT band stretch. Sit on the ground with your legs straight, then bend your right knee and cross your right foot over your left leg. Twist your torso to the right, placing your left elbow on the outside of your right knee. Hold for 15-30 seconds, then repeat on the opposite side.
The forward-folding IT stretch is another option. Start standing with your feet together, then cross your right leg over your left, setting your right foot flat on the outside of your left foot. Reach down toward your feet, bending as far as comfortable to feel a stretch. Breathe deeply as you hold for 30 seconds, then switch sides. You can also try the back-lying IT band stretch. Lie on your back with your knees bent 90 degrees, then lift your right leg and hook your right ankle around your left knee. Stretch both legs down toward the ground to the right, holding for 30 seconds before repeating on the left side.
Strengthening exercises
In addition to stretching, strengthening the muscles that attach to the IT band is essential for preventing iliotibial band syndrome. Hip hikes are an effective exercise to target the gluteus medius. Stand sideways on a step with your left leg hanging off the edge, then lift your left hip up while keeping your right leg straight. Continue this movement for 12-15 repetitions before switching sides.
Heel drops are another beneficial exercise. Stand on a step with one foot, extending the opposite foot in front of you. Slowly squat down as though you are going to step forward, then return to the starting position while keeping your pelvis square. Perform 2-3 sets of 15-20 repetitions. Side plank pose is also effective for strengthening the hip abductors. Come into plank pose, then press into your left arm as you roll to your right side. Stack your ankles or drop your left shin to the floor for support, then lift your right leg as high as you can. Hold this position for up to one minute, then repeat on the opposite side.
Side leg abduction is another important exercise. Lie on your side with your affected leg on top, then straighten your top leg and draw your toes toward you as you press out through your heel. Slowly lift your top leg up and slightly back, then return to the starting position. Perform 2-3 sets of 10 repetitions on each side. Finally, the clamshell exercise targets the gluteus medius. Lie on your side with your affected leg on top and your knees bent. Lift your top knee as high as you can without letting your body roll backward, then lower the knee and repeat for 2-3 sets of 10 repetitions on each leg.
Proper form and technique
When performing stretches and exercises for iliotibial band syndrome, proper form and technique are crucial to avoid further injury and ensure maximum effectiveness. Always warm up before stretching or exercising, and never force your body into a painful position. When stretching, hold each stretch for 15-30 seconds without bouncing, and breathe deeply to help your muscles relax. Aim to stretch 2-3 times per day, especially after physical activity.
For strengthening exercises, focus on maintaining proper alignment and engaging your core to support your spine. Start with a low number of repetitions and gradually increase as your strength improves. If any exercise causes pain, stop immediately and consult a healthcare professional. Remember to listen to your body and progress slowly to avoid overloading the IT band and surrounding muscles. By consistently incorporating these stretches and exercises into your routine with proper form and technique, you can help alleviate IT band tightness and prevent the development of iliotibial band syndrome.
Prevention and Long-Term Management
Training modifications
Runners with iliotibial band syndrome should modify their training to reduce stress on the IT band and promote healing. Cutting running volume by 50% and decreasing intensity for 2-4 weeks can help maintain some running while allowing the IT band to recover. Cross-training with biking, swimming, and weightlifting maintains cardiovascular fitness without the impact of running. Analyzing running form and making adjustments like shortening stride length, increasing cadence to 170-180 steps per minute, and incorporating running drills on soft surfaces 2-3 times per week can improve running efficiency and reduce strain on the IT band.
Proper footwear and gear
Wearing appropriate running shoes is crucial for preventing and managing ITBS. Shoes should provide adequate support, control pronation, and have stiff soles to reduce stress on the knees. Replacing running shoes every 300-500 miles or 3-4 months ensures they maintain their shock-absorbing capabilities. High mileage runners may benefit from alternating between two pairs of shoes to allow the materials to recover between runs. Properly fitted shoes, along with custom orthotics if needed, can correct anatomical issues like excessive pronation that contribute to IT band syndrome.

Regular maintenance routines
Incorporating regular self-care routines helps prevent and manage iliotibial band syndrome. A thorough warm-up before running, including dynamic stretches and activation exercises, prepares the body for activity and reduces risk of injury. Post-run, techniques like foam rolling, stretching, and massage target tightness in the hip and thigh muscles that attach to the IT band. Focusing on the gluteal muscles, tensor fascia lata, and quadriceps helps restore flexibility and balance. Consistency is key, aiming for brief 3-4 minute sessions multiple times daily. Other tools like compression boots, cupping, and flossing can provide additional relief and promote recovery. Proper rest and recovery, especially after long runs or intense workouts, allows the IT band and surrounding tissues to heal and adapt to training stresses. By implementing these preventive strategies and listening to their bodies, runners can minimize the risk of developing ITBS and promote long-term health and performance.
