What Is Iliotibial Band Syndrome?
Iliotibial band syndrome (ITBS) is an overuse injury where the thick band
of tissue on the outer thigh becomes irritated, causing pain on the outside of the
knee.
The iliotibial (IT) band runs from the hip to the shin and helps stabilise the knee during
movement. When the band repeatedly rubs against the outer knee bone during activities like
running, cycling, or hiking, it can become inflamed and painful.
ITBS is one of the most common causes of lateral (outer side) knee pain in athletes,
especially runners.
What Causes Iliotibial Band Syndrome?
ITBS can occur due to a combination of overuse, biomechanical issues (movement and alignment problems), and inappropriate training habits. Common causes include:
- Repetitive activities such as long-distance running, cycling, or stair climbing that repeatedly bend and straighten the knee
- Sudden changes in training load, including increased distance, speed, or hill running without giving the knee enough time to adjust
- Muscle weakness or imbalance, particularly in the hips, gluteal muscles, or core, leading to reduced stability and abnormal knee movement
- Tightness of the IT band or surrounding structures limits flexibility and heightens friction as the band slides over the outer knee
- Inadequate footwear or worn-out shoes that fail to provide proper support, increasing strain on the legs and altering running form
- Poor alignment or foot mechanics, such as flat feet, knock knees, or leg length differences, change the way forces pass through the leg and increase pressure on the IT band during movement
What Are the Symptoms of Iliotibial Band Syndrome?
Symptoms of ITBS may include:
- Pain on the outer knee that increases with activity. It often starts after a certain distance of running or cycling, worsens with downhill running, stair climbing, or rising from sitting, and usually eases with rest.
- Tenderness or swelling on the outer knee
- Snapping or popping sensation when bending and straightening the knee
If not managed early, iliotibial band syndrome can become persistent and limit both sports performance and daily movement.
If left untreated, iliotibial band syndrome can cause persistent pain and restrict your ability to stay active. If you have ongoing discomfort on the outer knee or pain with running, stairs, or daily movement, consult a knee specialist for proper assessment and a personalised treatment plan. How Is Iliotibial Band Syndrome Diagnosed?
ITBS is usually diagnosed through a clinical assessment based on symptoms and physical examination. This typically involves:
- Review of medical history to understand training patterns, onset of pain, and aggravating activities
- Physical examination checking for tenderness on the outer knee, IT band tightness, and hip or core weakness
- Movement analysis, such as observing running gait or a single-leg squat, to identify biomechanical factors that contribute to IT band strain
Imaging tests such as X-rays or MRI are rarely required unless another cause of knee pain is suspected, such as runner’s knee, a meniscus tear, ligament injury, or knee arthritis.
Iliotibial Band Syndrome Treatment
Treatment for ITBS aims to relieve pain, address underlying causes, and restore full activity. Most people respond well to non-surgical approaches, while surgery is considered for persistence cases that do not improve with thorough rehabilitation and other conservative treatments.
| Treatment | Description & Purpose |
|---|---|
| Non-Surgical Management | |
| Pain Management | Rest, ice packs, and oral non-steroidal anti-inflammatory drugs (NSAIDs) can help reduce pain and swelling. Corticosteroid injections may be used in selected cases for short-term relief of severe inflammation. |
| Activity Modification | Reducing or adjusting activities that worsen pain, such as running, cycling, or stair climbing, with gradual return once symptoms improve. |
| Physiotherapy | A tailored rehabilitation programme focusing on stretching tight structures, foam rolling, and strengthening the hips, gluteal muscles, and core to improve stability and reduce stress on the IT band. |
| Supportive Devices | Shoe orthotics or footwear adjustments to improve alignment, reduce abnormal loading, and relieve strain on the IT band. |
| Manual Therapy | Soft tissue release and myofascial techniques applied by a therapist to reduce IT band tightness and improve flexibility. |
| Shockwave therapy | A non-invasive treatment that uses sound waves to stimulate healing and reduce inflammation, helping to relieve pain and promote recovery. |
| Surgical Management | |
| IT Band Release or Lengthening | A surgical procedure where a small section of the iliotibial band is cut or lengthened to reduce tension and friction at the knee. Considered only when ITBS symptoms remain severe despite structured conservative care. |
| Bursectomy | Removal of an inflamed bursa beneath the IT band when it contributes to persistent irritation and pain. |
How to Prevent Iliotibial Band Syndrome?
The risk of ITBS can be reduced by strengthening the muscles around the hip and knee, maintaining flexibility, and following proper training practices. Preventive measures include:
- Incorporating hip, gluteal, and core strengthening exercises to improve stability
- Progressively increasing running distance and intensity rather than making abrupt changes
- Wearing supportive footwear and replacing worn-out shoes regularly
- Warming up before activity and stretching afterwards, especially the hips and thighs
- Mixing in low-impact activities such as swimming or cycling to reduce repetitive stress on the knees
- Limiting excessive downhill running, which increases friction and stress on the IT band
When Should You Seek Medical Attention?
You should see a doctor or sports medicine specialist if knee pain persists despite rest,
limits your daily activities, or keeps recurring when you try to return to exercise.
Early assessment and treatment can prevent ITBS from becoming chronic and support a gradual,
well-managed return to sport.
At Apex Sports Clinic, we carefully assess your condition and provide personalised treatment plans
to manage ITBS and help you maintain an active lifestyle.
Every patient deserves a treatment plan tailored to their needs. We start with non-surgical approaches before considering more invasive interventions.

Frequently Asked Questions (FAQs)
There is no quick fix for iliotibial band syndrome, but symptoms often improve with rest, ice, activity modification, and physiotherapy exercises. Addressing hip and core weakness, improving flexibility, and correcting training habits are key to recovery. Corticosteroid injections or shockwave therapy may be considered in selected cases for persistent pain. It is advisable to consult your doctor or specialist to determine the most appropriate treatment plan for your condition.
Iliotibial band syndrome usually improves within four to eight weeks with rest, stretching, and physiotherapy, but recovery may take longer if underlying movement patterns or training errors are not corrected. More persistent cases can require several months of structured rehabilitation. As recovery timelines vary between individuals, it is advisable to consult your doctor or specialist for a personalised estimate based on your condition.
The main cause of iliotibial band syndrome is repetitive friction of the IT band against the outer knee bone during activities like running or cycling. This friction often results from a combination of training overload, hip or core weakness, and biomechanical factors such as poor alignment or footwear. Less commonly, anatomical variations or arthritis-related changes may contribute.
Stretching the iliotibial band itself is difficult, but targeted stretches for the hips, thighs, and surrounding muscles can reduce tension and improve movement. Stretching should be gentle and combined with strengthening exercises rather than used alone. Overstretching or stretching into pain can worsen symptoms. Always follow the guidance of your physiotherapist or specialist for personalised advice appropriate to your condition.
Massage and foam rolling can help relieve tightness in the muscles around the IT band and may reduce discomfort, but they do not directly stretch the band itself. When combined with physiotherapy, strengthening, and activity modification, massage can be used to complement your overall treatment plan. Always follow the advice of your doctor or specialist to ensure massage is appropriate for your condition.
Conditions that can mimic iliotibial band syndrome include runner’s knee (patellofemoral pain syndrome), meniscus tears, lateral collateral ligament injuries, and knee arthritis. These conditions also cause pain around the knee but may present with different patterns, such as pain at the front, locking, or instability. Accurate diagnosis usually requires a clinical examination and, if necessary, imaging.
Walking places relatively little stress on the iliotibial band and is usually well tolerated, but problems can arise if the band becomes irritated or inflamed, as in iliotibial band syndrome (ITBS). In such cases, long distances or brisk walking may aggravate symptoms, while shorter, flat-surface walks are often more manageable. Gentle strengthening and stretching alongside walking can help maintain mobility. If you have ITBS, it is advisable to consult your doctor for personalised guidance.
A tight iliotibial band often feels like stiffness or tension along the outer thigh and knee, sometimes with tenderness to touch or discomfort during movement. Some people also notice a snapping sensation as the band moves over the knee. While mild tightness may not always cause symptoms, persistent tightness can increase friction and contribute to iliotibial band syndrome. If you are experiencing pain with these sensations, it is advisable to consult a doctor or specialist.
Iliotibial band syndrome is usually diagnosed by a doctor or specialist through clinical assessment, which includes reviewing symptoms, medical history, and performing a physical examination. This may involve checking for tenderness on the outer knee, assessing IT band flexibility, and evaluating hip and core strength. Running gait or movement analysis can also help identify contributing factors. Imaging such as X-rays or MRI is seldom needed unless another knee condition is suspected.
A knee brace is not usually necessary for iliotibial band syndrome, but some people may experience temporary relief with supportive taping or bracing that improves alignment and reduces strain. Treatment of ITBS typically involves physiotherapy, strengthening, stretching, and adjusting activity to address underlying causes. Bracing should not be relied on as a long-term solution. It is advisable to consult your doctor or specialist to determine if a brace would be beneficial for your condition.
Poor footwear can contribute to iliotibial band syndrome by altering running mechanics and increasing strain on the legs. Worn-out shoes, inadequate cushioning, or lack of support may lead to abnormal movement patterns that place extra stress on the IT band. Choosing supportive footwear and replacing shoes regularly reduces this risk.
If left untreated, iliotibial band syndrome can cause persistent pain on the outer knee and progressively limit activity levels. Continuing to train through pain may worsen inflammation and increase the risk of developing chronic discomfort or secondary knee issues. Most cases can improve with early rest, physiotherapy, and strengthening exercises. If you are experiencing ongoing outer knee pain despite rest, it is advisable to consult a doctor or specialist for assessment and management.
You should be concerned about hip or leg pain if it persists despite rest, interferes with daily activities, or worsens with movement. Pain associated with swelling, instability, or difficulty bearing weight may also indicate a more serious condition. Occasional tightness is common, but ongoing or worsening symptoms warrant further evaluation. If you are experiencing persistent hip or leg pain, it is advisable to consult a doctor or specialist.
There is no single best treatment for iliotibial band syndrome, as management depends on individual causes and severity. Most people improve with a combination of rest, activity modification, physiotherapy exercises, and stretching. Supportive strategies such as orthotics, manual therapy, or shockwave therapy may also be considered in selected cases. Surgery is rarely needed and reserved for persistent cases. If you are experiencing ongoing symptoms, it is advisable to consult a knee specialist.
