Iliotibial Band Syndrome: Causes, Symptoms, and Treatment Options

For runners, cyclists, and active individuals, iliotibial band syndrome (ITBS) is one of the most common causes of pain on the outer side of the knee. This condition occurs when the iliotibial (IT) band, a thick band of tissue that runs along the outside of the thigh from the hip to the knee, becomes irritated and inflamed. ITBS can significantly limit your ability to stay active, but with the right treatment plan, most people can recover and return to their normal activities. In this article, we’ll explain what causes iliotibial band syndrome, how to recognise the symptoms, and the most effective treatment options.

What is Iliotibial Band Syndrome?

Iliotibial band syndrome is an overuse injury that affects the iliotibial band, a fibrous tissue that runs along the outside of the thigh. The IT band helps stabilise the knee during activities like running and cycling. When the IT band becomes too tight or is repeatedly irritated from friction, it can rub against the outer part of the knee, leading to inflammation and pain.

Common Causes of ITBS:

1. Overuse and Repetitive Motion: ITBS is most commonly caused by repetitive activities such as running, cycling, or hiking, which require constant bending and extending of the knee.

2. Weak Hip Muscles: Weakness in the hip abductors or other muscles surrounding the pelvis can lead to increased strain on the IT band during movement, contributing to ITBS.

3. Improper Running Form: Poor running mechanics, such as excessive inward rotation of the knee or overstriding, can increase the likelihood of developing ITBS.

4. Training Errors: Rapidly increasing mileage or intensity without allowing adequate time for recovery can also contribute to ITBS. Running on uneven or sloped surfaces may aggravate the condition further.

Symptoms of Iliotibial Band Syndrome

The hallmark symptom of iliotibial band syndrome is pain on the outside of the knee, but the severity and onset of symptoms can vary depending on the individual and the progression of the condition.

Key Symptoms Include:

• Lateral Knee Pain: Pain is typically felt on the outside of the knee and may worsen with activity. The pain is usually sharp and may start gradually before becoming more intense.
• Tenderness and Swelling: The area around the knee may feel tender to the touch, and in some cases, mild swelling may be present.
• Pain During Movement: Pain often worsens with activities that involve repetitive knee bending, such as running downhill or cycling. The discomfort may lessen with rest but can return when activity is resumed.
• Tightness in the Hip or Thigh: Some individuals with ITBS may also experience tightness in the hip or thigh due to the IT band’s attachment to the pelvis.

Diagnosis of Iliotibial Band Syndrome

A healthcare professional can diagnose iliotibial band syndrome through a physical examination and by reviewing your activity history. They will assess your movement patterns, strength, and flexibility to determine whether ITBS is the cause of your symptoms.

Diagnostic Steps Include:

1. Physical Examination: Your doctor will check for tenderness and pain on the outer side of the knee. They may also assess the range of motion and strength of the hip, thigh, and knee muscles.

2. Activity Review: A detailed review of your exercise routine, training intensity, and footwear will help identify any contributing factors.

3. Imaging Tests: In most cases, imaging tests like X-rays or MRIs are not necessary to diagnose ITBS. However, they may be used to rule out other potential causes of knee pain, such as ligament injuries or cartilage damage.

Treatment Options for Iliotibial Band Syndrome

The treatment for ITBS focuses on reducing inflammation, addressing the underlying causes, and improving flexibility and strength. Most cases of ITBS can be effectively treated with conservative measures, but recovery times can vary depending on the severity of the condition.

Non-Surgical Treatments:

1. Rest and Activity Modification: Reducing or stopping the activities that aggravate the condition is the first step in treatment. Rest allows the inflammation to subside, and low-impact exercises like swimming can help maintain fitness without worsening the symptoms.

2. Physical Therapy: A physical therapist can design a rehabilitation programme to improve flexibility and strengthen the muscles surrounding the hip and knee. Key areas of focus include hip abductor strengthening, stretching the IT band, and improving overall running or cycling mechanics.

3. Stretching and Foam Rolling: Regular stretching of the IT band, hamstrings, and quadriceps can help reduce tension in the knee. Foam rolling the IT band can also improve mobility and relieve tightness.

4. Anti-Inflammatory Medications: Over-the-counter non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen can help reduce pain and inflammation associated with ITBS.

5. Orthotics and Footwear Adjustments: Custom orthotics or proper footwear can help correct biomechanical issues such as overpronation, which can contribute to ITBS.

Advanced Treatment Options:

In cases where conservative treatments do not provide sufficient relief, more advanced interventions may be recommended.

1. Corticosteroid Injections: In some cases, corticosteroid injections may be used to reduce inflammation around the IT band. These injections can provide temporary relief but are not a long-term solution.

2. Surgical Options: Surgery is rarely required for iliotibial band syndrome, but in severe cases where conservative treatment fails, a procedure to release or lengthen the IT band may be considered.

Preventing Iliotibial Band Syndrome Preventing ITBS involves addressing the factors that contribute to the condition, such as muscle weakness, poor flexibility, and improper training habits.

1. Strengthen Hip and Thigh Muscles: Regularly performing exercises to strengthen the hip abductors, glutes, and quadriceps can help stabilise the knee and reduce the risk of ITBS. Exercises like clamshells, side-lying leg raises, and bridges are particularly effective.

2. Incorporate Stretching: Stretching the IT band, hamstrings, and quadriceps after workouts can help prevent tightness. Use a foam roller to target the IT band and surrounding muscles.

3. Gradually Increase Training Load: Avoid rapid increases in mileage or intensity. Instead, gradually increase your training volume, allowing your body to adapt to new demands.

4. Check Your Running Form: Ensure proper running mechanics by keeping your knees aligned and avoiding excessive inward rotation. Consider a gait analysis with a professional to identify any biomechanical issues.

5. Wear Appropriate Footwear: Wearing supportive, well-fitting shoes that suit your foot mechanics can reduce strain on the IT band. Consider using orthotics if you have flat feet or overpronation.

Managing Iliotibial Band Syndrome

Iliotibial band syndrome is a common overuse injury, but with the right treatment and prevention strategies, it’s possible to manage the condition and return to pain-free activity. Focusing on muscle strength, flexibility, and proper mechanics can go a long way in preventing ITBS from recurring. If you’re struggling with knee pain or suspect you have ITBS, MSK Doctors can help.
