Iliotibial Band Syndrome (ITB Syndrome) is one of the most common causes of lateral (outer) knee pain, particularly in runners, cyclists, and active individuals. It occurs when the iliotibial band—a thick band of connective tissue running from the hip to the outside of the knee—becomes tight or inflamed and rubs against the femur.
Sharp or burning pain on the outside of the knee
Pain that worsens during activity (especially running downhill)
Tenderness along the outer thigh
Tightness in the hip or lateral leg
Clicking or snapping sensation near the knee
If left untreated, ITB syndrome can significantly impact mobility and athletic performance.
A simple way to recognise ITB syndrome is by locating where the pain is most prominent.
The discomfort typically occurs over the lateral epicondyle of the knee—a small bony bump on the outer side of your knee. You can find this area by sliding your hand down the outside of your thigh towards your knee. As you approach the joint, you’ll feel a noticeable bump—this is where the iliotibial band commonly becomes irritated.
While pressing on this area, gently bend and straighten your knee. Pain often becomes more noticeable or sharper with knee flexion (bending), which is a common sign associated with ITB syndrome.
If pressing on this point reproduces your familiar pain—especially when moving the knee—it may indicate ITB syndrome. Symptoms are often more noticeable during activities such as running, particularly downhill, or after repetitive movement.
If you’re unsure or the pain persists, a professional assessment can help confirm the diagnosis and guide the most effective treatment.
Most cases of ITB syndrome improve with conservative treatments such as rest, physiotherapy, stretching, and strengthening exercises. However, when symptoms persist despite these approaches, injections may be recommended.
Chronic pain lasting several weeks or months
Failure to respond to physiotherapy
Severe inflammation limiting daily activities
Recurring ITB issues in athletes
Injections are typically considered a second-line treatment, aimed at reducing inflammation and enabling more effective rehabilitation.
Corticosteroid injections are the most commonly used treatment for ITB syndrome when conservative care fails.
Benefits:
Rapid reduction in inflammation
Significant pain relief
Helps restore movement quickly
Considerations:
Effects may be temporary
Repeated use can weaken surrounding tissues
Usually combined with physiotherapy for best results
PRP therapy uses a concentration of your own platelets to promote healing in damaged tissues.
Benefits:
Supports natural healing processes
May provide longer-term improvement
Lower risk of adverse reactions
Considerations:
Results can take longer to appear
Typically more expensive than steroid injections
Evidence is still evolving
Occasionally used to improve lubrication around the knee joint and reduce irritation.
Injections are typically performed under ultrasound guidance to ensure precision. The medication is delivered directly to the area where the IT band is inflamed.
Skin is cleaned and numbed
Ultrasound is used to locate the affected area
Injection is administered into the inflamed tissue
Procedure usually takes 10–20 minutes
Most patients can return home the same day.
Recovery is usually quick, but proper aftercare is essential for long-term success.
Mild soreness for 24–48 hours
Gradual reduction in pain over several days
Return to activity guided by a physiotherapist
Avoid strenuous activity for a few days
Follow a structured rehab program
Focus on hip and glute strengthening
Maintain flexibility in the IT band and surrounding muscles
Studies and clinical experience show that injections—particularly corticosteroids—can provide significant short-term pain relief. However, they are most effective when combined with rehabilitation.
Injections treat inflammation, not the root cause
Long-term success depends on correcting biomechanics
Strength and mobility work are essential
While generally safe, ITB syndrome injections do carry some risks:
Temporary pain at the injection site
Infection (rare)
Tissue weakening (with repeated steroid use)
Allergic reaction (very rare)
A qualified clinician will assess your suitability before recommending treatment.
Before considering injections, or alongside them, the following treatments are often recommended:
Physiotherapy and guided exercise programs
Foam rolling and stretching routines
Activity modification
Biomechanical assessment (e.g., gait analysis)
Orthotics (if needed)
You should seek professional advice if:
Pain persists for more than 2–4 weeks
Symptoms worsen despite rest
You are unable to return to normal activity
Pain interferes with daily life
Early intervention can prevent chronic issues and speed up recovery.
Lateral knee pain is not always caused by ITB syndrome. Several other conditions can present with similar symptoms, and accurate diagnosis is essential to ensure the right treatment approach. At Physio Soton Clinic, we provide expert assessment, ultrasound imaging, and targeted treatments for a range of knee conditions.
Knee osteoarthritis is a degenerative joint condition that can cause pain, stiffness, and swelling. Unlike ITB syndrome, symptoms are often more widespread within the knee and may worsen with prolonged activity or after rest. Treatment options may include physiotherapy, strengthening programmes, and injection therapy such as corticosteroids or hyaluronic acid.
Meniscal injuries involve damage to the cartilage within the knee joint and are common in both athletes and the general population. Symptoms can include joint line pain, locking, clicking, or swelling. These injuries can sometimes mimic ITB syndrome, making clinical assessment and imaging important. Treatment may include rehabilitation or, in some cases, injection therapy to reduce inflammation.
Tendinopathies, such as patellar tendon pain or quadriceps tendon issues, can also contribute to anterior or lateral knee discomfort. These conditions are typically related to overuse or load management issues and require a structured rehabilitation programme. In some cases, injection therapies such as PRP may be considered to support healing.
ITB syndrome injections can be an effective tool for reducing pain and inflammation, especially when other treatments have not worked. However, they are not a standalone solution.
For the best results, injections should be part of a comprehensive treatment plan that includes physiotherapy, strength training, and movement correction.

How long do ITB injections last?
Relief can last from a few weeks to several months, depending on the individual and type of injection.
Are injections painful?
Most patients experience minimal discomfort due to local anaesthetic and guided techniques.
Can I run after an injection?
You should avoid running initially and gradually return under professional guidance.
Do injections cure ITB syndrome?
They help manage symptoms but do not address underlying causes such as muscle imbalance or poor biomechanics.
If you’re struggling with persistent outer knee pain and think ITB syndrome injections may help, consult a qualified specialist for a full assessment and personalised treatment plan.
