Pain on the Outside of Your Knee When Running?

Could it be iliotibial band syndrome?

Iliotibial band syndrome, often shortened to ITBS, is one possible cause of pain around the outside of the knee. It can affect runners and people taking part in other activities involving repeated knee movement.

Pain in this location does not confirm ITBS. Joint, meniscus, ligament or other problems may produce similar symptoms, so an assessment is useful if pain persists or limits activity.

What is the iliotibial band?

The iliotibial band is a strong band of connective tissue running along the outside of the thigh from the hip region towards the upper tibia, just below the knee. It works with surrounding muscles to help control the leg.

Symptoms can develop where tissues around the outer knee become irritated during repeated loading. Training demands, individual movement patterns and recovery may all be relevant.

It is too simplistic to assume that every case results from “uneven weight distribution”, an inward-rolling foot or weak hips. The treatment plan should reflect the individual findings.

What symptoms might you notice?

• Pain or a burning sensation around the outside of the knee during or after running.
• Discomfort that builds with repeated knee bending.
• Local tenderness, sometimes with swelling.
• Symptoms that settle with reduced activity but recur when training resumes.

Symptoms vary. Marked swelling, locking, an acute twisting injury or inability to bear weight should prompt consideration of other causes.

How is outer knee pain assessed?

Your clinician asks about onset, pain location, training changes, previous injury and the activities that bring symptoms on. Examination may include the knee, hip, strength and relevant movement patterns.

Do you need an ultrasound scan?

Ultrasound may help answer selected questions about accessible soft tissues around the knee. It should be interpreted alongside the history and examination, rather than used alone to label pain as ITBS.

Not everyone needs a scan. Other imaging or referral may be more appropriate if a different injury is suspected.

Should you keep running?

Pause runs that reproduce knee pain rather than repeatedly pushing through it. Adjust distance, pace, hills or other aggravating demands with advice where needed.

Comfortable alternative activity may help maintain fitness while symptoms settle. If walking or everyday movement is painful, seek assessment before adding more exercise.

There is no single rest period or fixed twelve-week recovery deadline that applies to everyone. Progress depends on symptoms, function and the demands of your sport.

What does rehabilitation involve?

Flexibility work, taping or other measures may be considered as part of a wider plan. Forceful stretching or rolling directly over a painful outer knee is not a requirement for recovery.

Use our physiotherapy information or contact the team to discuss assessment and rehabilitation.

Can shoes, insoles or a knee support help?

Footwear should be comfortable and appropriate for your activity. A clinician may consider shoe fit, wear and any recent changes alongside the rest of the assessment.

No single shoe type suits every runner. Switching to barefoot or minimalist footwear is not a general treatment recommendation for ITBS, and abrupt changes can introduce new problems.

Orthotics or a support may be useful for an identified need, but they are not automatically required. A bandage that increases discomfort should not be worn simply because it feels supportive.

When might an ultrasound-guided injection be considered?

A clinician may discuss a local corticosteroid injection in selected cases after reviewing the diagnosis and other management options. The intended target, likely benefit and limitations should be explained.

Research includes a small trial of steroid injection in runners with recent-onset IT band symptoms and a published case report of ultrasound-guided treatment. These do not establish a guaranteed cure or show that rehabilitation is unnecessary.

Ultrasound can help visualise structures and guide placement, but it does not eliminate procedural risk. Discuss infection, bleeding, a pain flare, medicine-specific effects and relevant tissue risks before deciding.

How do you return to running?

1. Settle the activities that aggravate symptoms.
2. Restore comfortable everyday movement and appropriate strength.
3. Introduce short, manageable running sessions when advised.
4. Increase demands gradually, monitoring symptoms during and after activity.
5. Review the plan if pain repeatedly returns.

The goal is a sustainable return to your usual activity. No programme can guarantee that symptoms will never recur.

When should you seek urgent advice?

Contact NHS 111 if the knee is very painful, cannot bear weight or move normally, is badly swollen or has changed shape, locks or gives way, or is red and hot with fever or shivering.

Persistent symptoms that limit daily life or return whenever you run also deserve assessment. Do not assume all outer knee pain is a routine overuse problem.
