What is Iliotibial Band Syndrome – also known as ITB Syndrome?
ITBS is a common injury caused by overuse in which the iliotibial band—a thick band of connective tissue running down the outer side of the leg from the hip to below the knee. It’s particularly common in runners, cyclists, and other endurance athletes.
Types of Iliotibial Band Injuries
- Acute ITBS: Sudden onset pain following a new or intense activity.
- Chronic ITBS: Persistent or recurring pain from prolonged irritation.
- Iliotibial Band Friction Syndrome: Caused by repetitive rubbing over the lateral femoral condyle during knee movement.
- Proximal ITBS: Pain near the hip where the IT band originates. It is less common but often linked with weak gluteal muscles.
How Common is ITBS?
ITBS accounts for up to 12% of running-related injuries and is the second most common cause of lateral knee pain in runners. It’s also frequently seen in hikers, cyclists, and weightlifters.
Symptoms of Iliotibial Band (ITB) Syndrome
- Pain on the outer side of the knee
- This pain is often described to be sharp or burning, especially during or after running or cycling.
- Pain that worsens with activity
- Especially downhill running, repetitive squatting, or prolonged walking.
- Tenderness over the lateral femoral condyle
- Pressing on the outside of the knee may reproduce pain.
- Snapping or popping sensation
- Some people feel a snapping as the IT band moves over the knee during motion.
- Swelling or thickening at the outside of the knee
- Mild local swelling or a feeling of tightness is sometimes noted.
- Pain when the knee is flexed to ~30 degrees
- 30 degrees flexion is the point where the IT band is most likely to rub over the bone.
- Hip pain (in proximal ITB syndrome)
- It is less common, but some may experience lateral hip pain if the upper portion of the band is irritated.
Causes of IT Band Syndrome
- Repetitive Knee Motion: Common in running and cycling.
- Training Errors: Sudden increases in intensity or distance.
- Anatomical Factors: Leg length differences, bowed legs, or excessive foot pronation.
- Muscle Imbalances: Weak gluteal and hip muscles can overload the IT band.
- Poor Surfaces: Running on cambered roads or trails.
- Worn-out Footwear: Inadequate support can alter gait and load.
Risk Factors
The following is a list of possible risk factors that can lead to IT Band syndrome. Of course, other activities may also cause to it.
- Long-distance or downhill running
- Unsupportive or old shoes
- High training volume without rest days
- Poor biomechanics (e.g., bowed legs, overpronation)
- Tight IT band
- History of knee injuries
Potential Complications
It is important that your medical provider is aware of the potential complications of ITB syndrome. The team at Access Ortho are skilled in the care of musculoskeletal injuries and will be able to discuss these in detail with you.
Persistent Knee or Hip Pain
Ongoing irritation of the IT band can lead to chronic discomfort, particularly during activities like running, walking, or climbing stairs. Pain may often persist after exercise, affecting rest and sleep.
Decreased Athletic Performance
Athletes may notice a decline in endurance, strength, or pace due to pain or the need to modify training. Persistent symptoms can lead to missed training sessions and competition withdrawal.
Compensatory Movement Patterns Leading to Secondary Injuries
To avoid ITB pain, a person may adopt abnormal movement patterns, increasing the risk of developing issues in the lower back, opposite leg, or feet, such as shin splints, Achilles tendinopathy, or plantar fasciitis.
Chronic Inflammation or Scarring of the IT Band
Without proper treatment, the IT band can develop thickened, fibrotic areas that cause persistent irritation and are more resistant to conservative therapies.
Restricted Mobility Affecting Daily Function
Pain and tightness may limit the ability to squat, sit comfortably, or walk long distances, impacting daily tasks and overall quality of life.
Diagnosis and Testing
The diagnosis is clinical and based on history, symptoms, and movement assessment. The Access Orthopaedic team will carry out a comprehensive assessment to ensure you receive a correct diagnosis.
Tests Used:
- Noble Compression Test: Pain when pressure is applied to the IT band during knee flexion.
- Ober’s Test: Assesses IT band tightness.
- Thomas Test / Modified Renne’s Test: Evaluates hip flexibility and ITB tension.
- Imaging: Ultrasound or MRI to rule out other conditions.
Special Considerations
Runners vs. Cyclists:
Runners typically feel pain during foot strike; cyclists during the pedal downstroke.
Age Differences:
- Adolescents: Often related to growth and biomechanics.
- Adults: Training errors and poor conditioning.
- Older Adults: May involve associated conditions like hip bursitis or arthritis.
Other Causes of Lateral Knee Pain:
ITBS should be distinguished from:
- Lateral meniscus tears
- LCL injuries
- Patellofemoral pain syndrome
Treatment Options
Conservative Treatment (First Line):
- Rest & Activity Modification: Reduce load on the IT band.
- Ice Therapy: Manage inflammation in acute phases.
- Anti-Inflammatory Medications: For symptom relief.
- Physiotherapy: Focuses on hip and core strength, stretching, and gait retraining.
- Foam Rolling & Massage: To relieve IT band tension.
- Footwear & Orthotics: Proper shoes or inserts to support alignment.
In Severe or Chronic Cases:
- Corticosteroid Injections: For targeted pain relief.
- Surgery: Rare; may involve IT band release or debridement if conservative measures fail.
Non-Surgical Treatment in Detail
Physiotherapy is the cornerstone of recovery:
- IT band and gluteal stretches
- Hip abductor and core strengthening
- Manual therapy to reduce tension
- Gradual return to activity with guided programming
When is Surgery Needed?
Surgical treatment is considered only if:
- Symptoms persist beyond 6 months
- Conservative treatment fails
- MRI shows thickened or scarred IT band
- Procedures include IT band lengthening or arthroscopic removal of inflamed tissue.
Prevention Strategies
The following strategies may help with preventing IT Band Syndrome.
- Warm-up and cool down properly
- Gradually increase training (don’t start sudden intense training)
- Regular stretching and foam rolling
- Strengthening the glutes and core
- Replace worn footwear regularly
- Avoid uneven running surfaces
- Ensure proper bike setup for cyclists
Prognosis and Recovery
With early and appropriate treatment, most people recover within 4–8 weeks. Chronic cases may take longer. Returning to sport must be gradual and guided by pain, strength, and mobility.
When to See a Specialist
If you have symptoms of ITB syndrome, you should see a medical practitioner who specialises in musculoskeletal injuries in the following situations.
- Pain that persists longer than 2 weeks despite rest
- Symptoms that interfere with daily life
- If your pain worsens or prevents weight-bearing
- If swelling or knee instability develops
- If you see no improvement with physiotherapy

FAQs About IT Band Syndrome
Can I continue running with ITBS?
It’s best to reduce or modify activity until symptoms improve. If you continue to train, it is likely your pain will take longer to go away.
Does ITBS go away?
Yes, with proper treatment and prevention strategies, full recovery is likely. If you follow the guidance of a medical practitioner knowledgeable in musculoskeletal injuries, you are likely to have a good outcome.
Is foam rolling helpful?
Yes, foam rolling can help, especially along the lateral thigh—but avoid direct rolling over the painful knee area.
Can it affect both knees?
ITB syndrome can affect both sides, although usually, one side is more affected in most people.
Will a brace help?
A knee strap or ITB-specific brace can provide relief but should not replace rehab. Ask your medical practitioner about the need for this.
Can weight training help?
Targeting hip and core strength is beneficial for recovery after ITB syndrome and can also help prevent the onset of symptoms.
Does Access Ortho treat IT Band Syndrome?
Yes, Access Ortho provides orthopaedic assessment, referral for physiotherapy, bracing, and surgical referral if needed.
