IT Band Syndrome

Iliotibial band syndrome (IT band syndrome or ITBS) is a common overuse injury that causes pain along the outside of the knee. It is especially common in runners and can also occur with cycling, hiking, or other repetitive lower-body activities. 

Dr. Michael Hoiles has created this page as a resource to help you better understand IT band syndrome, including common symptoms, contributing factors, treatment options, exercises, and when it may be appropriate to seek an assessment.

Quick Facts 

✔ IT band syndrome commonly causes pain on the outside of the knee. 

✔ It is particularly common in runners and other endurance athletes. 

✔ Sudden increases in running volume, hills, or training intensity can contribute. 

✔ Hip and lower-extremity strength and movement control may play a role. 

✔ Temporarily modifying aggravating activities can help settle symptoms. 

✔ Most cases respond well to progressive exercise and appropriate training modifications.

Anatomy

The iliotibial band (IT band) is a thick band of connective tissue that runs along the outside of the thigh from the hip region to the upper portion of the tibia near the knee. 

Several muscles around the hip interact with the IT band, including the tensor fasciae latae (TFL) and gluteal muscles. 

During running and other repetitive activities, the tissues around the outside of the knee are repeatedly loaded. IT band syndrome is thought to involve irritation or compression of sensitive tissues near the outer knee rather than simply an IT band that is “too tight.” 

​

 

What Is IT Band Syndrome? 

IT band syndrome is an overuse injury involving pain and irritation around the outside of the knee where the iliotibial band passes over the lateral femoral epicondyle. 

Symptoms often develop gradually and may initially occur only after running a certain distance. If the condition becomes more irritated, pain may begin earlier during activity or persist afterward. 

​

 

Common Causes and Risk Factors

IT band syndrome usually develops from a combination of training load and individual factors rather than one specific cause. 

Common contributors include: 

  • Rapid increases in running distance or intensity 

  • Increased hill or downhill running 

  • Sudden changes in training routine 

  • Inadequate recovery between workouts 

  • Hip or gluteal weakness 

  • Reduced lower-extremity movement control 

  • Returning to running too quickly after time off 

  • Repetitive cycling or endurance activity 

​

 

Common Symptoms:

  • Pain on the outside of the knee 

  • Sharp, aching, or burning discomfort during running 

  • Pain that begins after running a predictable distance 

  • Symptoms that worsen with continued activity 

  • Pain with downhill running 

  • Tenderness around the outside of the knee 

  • Discomfort when repeatedly bending and straightening the knee 

  • Symptoms that improve with rest but return with activity 

​

​

How Is It Diagnosed? 

Diagnosis is usually based on your symptoms and a physical examination. 

An assessment may include the knee and hip, strength testing, movement patterns, training history, and activities that reproduce your symptoms. 

Imaging is not usually required but may occasionally be recommended if another cause of lateral knee pain is suspected. 

​

Could My Pain Be Coming From Somewhere Else? 

Not all pain on the outside of the knee is caused by IT band syndrome. 

Other possibilities may include: 

  • Lateral meniscus injuries 

  • Lateral collateral ligament injuries 

  • Hamstring or tendon injuries 

  • Pain referred from the hip 

An assessment can help determine which structures are most likely contributing to your symptoms. 

​

 

What Helps? 

Treatment typically focuses on reducing irritation while gradually rebuilding the knee's ability to tolerate activity. 

Helpful strategies may include: 

  • Temporarily reducing aggravating running or activity 

  • Adjusting training volume or intensity 

  • Progressive hip and leg strengthening 

  • Improving lower-extremity movement control 

  • Gradually rebuilding running tolerance 

  • Addressing mobility restrictions when relevant 

  • Reviewing running or training habits 

  • Gradual return to hills and higher-intensity training 

Complete rest is rarely necessary for long periods. The goal is usually to modify activity enough to allow symptoms to settle while maintaining as much comfortable movement as possible. 

​

 

How Chiropractic Can Help 

Chiropractic care for IT band syndrome may include: 

  • Assessment of the knee, hip, and lower extremity 

  • Identifying training or movement factors contributing to symptoms 

  • Joint mobilization when appropriate 

  • Soft tissue treatment for surrounding muscles 

  • Hip and lower-extremity strengthening 

  • Exercise-based rehabilitation 

  • Guidance for gradually returning to running or sport 

Treatment should focus not only on reducing symptoms but also on improving the area's ability to tolerate the activities that caused the problem. 

​

 

Recovery Timeline 

Mild cases may improve within a few weeks, while more persistent cases can take 6–12 weeks or longer. 

Recovery depends on how irritated the area is, how long symptoms have been present, training demands, and how consistently aggravating loads are modified. 

A gradual return to running is usually more successful than repeatedly testing the knee with longer runs before it is ready. 

​

 

Can I Still Exercise With IT Band Syndrome? 

Usually, yes. 

Activities that do not significantly increase symptoms can often be continued. You may temporarily need to reduce running distance, speed, hills, or other movements that consistently aggravate the knee. 

Cycling, walking, strength training, or other forms of cardiovascular exercise may be options depending on your symptoms. 

​

 

Exercises Commonly Recommended 

Exercise selection should be based on your individual assessment and symptoms. 

Phase 1 – Settle Symptoms & Maintain Strength 

  • Glute bridges 

  • Side-lying hip abduction 

  • Clamshells 

  • Isometric wall sits 

  • Gentle hip mobility exercises 

Phase 2 – Build Strength & Control 

  • Lateral band walks 

  • Step-downs 

  • Split squats 

  • Single-leg bridges 

  • Single-leg balance exercises 

Phase 3 – Return to Running & Sport 

  • Single-leg squats 

  • Reverse or walking lunges 

  • Single-leg deadlifts 

  • Lateral step-downs 

  • Running-specific drills and progressive loading 

​

 

Common Mistakes That Slow Recovery

  • Continuing to run through increasing pain 

  • Increasing mileage too quickly 

  • Returning to hills too early 

  • Relying only on stretching or foam rolling 

  • Ignoring hip and leg strength 

  • Completely resting for long periods without rebuilding capacity 

  • Returning immediately to previous training volume once pain improves 

​

 

When Should You Seek an Assessment? 

  • Pain is preventing you from running or exercising 

  • Symptoms repeatedly return when you increase activity 

  • Pain is becoming more frequent or intense 

  • Symptoms are not improving despite modifying your training 

  • You are unsure whether the pain is actually coming from the IT band 

​

When Should I Worry? 

Seek medical attention sooner if you experience significant swelling, inability to bear weight, substantial loss of knee movement, significant trauma, fever or unexplained illness, or rapidly worsening symptoms.

Frequently Asked Questions 

Is IT band syndrome the same as runner's knee? 
Not usually. IT band syndrome typically causes pain on the outside of the knee, while patellofemoral pain commonly causes discomfort around or behind the kneecap. 

 

Should I stop running completely? 
Not always. Many people can continue some running if distance and intensity are modified so symptoms remain manageable. 

 

Should I stretch my IT band? 
Stretching or mobility work may feel helpful, but IT band syndrome is generally not simply caused by a “tight IT band.” Strength, training load, and movement control are often more important considerations. 

 

Does foam rolling help IT band syndrome? 
Foam rolling may temporarily reduce discomfort or tightness for some people, but it should usually be combined with appropriate strengthening and training modifications. 

 

How long does IT band syndrome take to heal? 
Many cases improve within several weeks, although more persistent cases may require 6–12 weeks or longer. 

 

Can weak glutes cause IT band syndrome? 
Hip strength and control can contribute in some people, but IT band syndrome usually results from several factors rather than one isolated weakness. 

​

 

Summary 

✔ IT band syndrome is a common cause of pain on the outside of the knee. 

✔ It frequently develops after changes in running or training load. 

✔ Temporarily modifying aggravating activities can help symptoms settle. 

✔ Hip and lower-extremity strengthening are often important parts of rehabilitation. 

✔ Most cases improve with appropriate load management and progressive exercise.
