Runner's Knee: Symptoms, Exercises and Return to Running

Symptoms and assessment of patellofemoral pain

Liverpool NHS patellofemoral-pain guidance describes discomfort with stairs, squatting, kneeling, running or prolonged sitting. Grinding or grating can occur without meaning that movement is damaging the knee.

Explain where the pain is, when it began, whether there was an injury and which activities bring it on. Include changes to running distance, speed, hills or other training. Do not assume that every front-of-knee symptom has the same cause.

A physiotherapist can assess movement and exercise needs. Ask which findings are relevant to your symptoms and how the proposed plan will address your goals, rather than relying on a single posture or footwear explanation.

Exercise and education form the treatment foundation

The 2024 BJSM best-practice guide recommends knee-targeted exercise, with hip-targeted exercise where appropriate, supported by education. Extra options such as taping, foot orthoses or running retraining should be selected for individual needs and preferences.

Discuss how to adjust activities that aggravate symptoms while maintaining suitable movement. The Liverpool leaflet describes changes to activity and strengthening the knee and hip. A brace or insole should not be treated as an automatic requirement for every painful knee.

Agree what symptoms are acceptable during practice, what response afterwards should prompt an adjustment and when progress will be reviewed. The goal is a workable plan that you understand and can continue.

Two exercise examples to discuss after assessment

Cambridge University Hospitals' exercise leaflet asks the physiotherapist to choose suitable movements and repetition counts. These examples are options to discuss, rather than a complete programme for every knee.

Controlled step-up

Face a step and place the affected foot on it. Step up by straightening that knee, then lower back down slowly. Keep the movement controlled and the kneecap aligned over the second toe. Ask about a suitable step height and support.

Supported single-leg dip

Stand on one leg near a stable support. Gently bend and straighten the standing knee, keeping the hip, knee and foot aligned. Ask whether this exercise suits your balance and current symptoms before practising it.

If an exercise increases symptoms, discuss an adjustment with your physiotherapist. Amount, range and progression should follow the assessed plan.

Planning a return to running

Ask your physiotherapist to agree a starting point based on your current symptoms, daily activities and running goals. A shared four-week calendar cannot account for every runner's starting ability or response.

• Confirm whether running is appropriate at this stage.
• Agree distance or duration, pace and any walk breaks.
• Discuss hills, speed sessions and other training separately.
• Record symptoms during the run and afterwards.
• Review the response before increasing the plan.

Ask what should prompt earlier contact, and how exercise and running sessions fit together. Our sports-injury guide explains return-to-activity decisions.

When knee symptoms need urgent medical assessment

NHS knee-pain guidance recommends urgent advice for a very painful knee, inability to move it or bear weight, marked swelling or a change in shape. Locking, giving way or painful clicking also needs urgent advice. Fever or feeling hot, cold or shivery with redness or heat around the knee can indicate infection.

These symptoms need assessment before following a running or home-exercise plan. Arrange clinical review for pain that is not improving rather than assuming that the label runner's knee explains everything.

Preparing for knee physiotherapy

Bring your training history, symptom notes and any previous medical advice. Our knee physiotherapy information explains assessment and individualized rehabilitation. The home physiotherapy guide covers exercise demonstrations and follow-up questions.

Do I have to stop every activity?

Discuss which activities can continue and which need a temporary change. Decisions depend on the symptoms and diagnosis, rather than the name runner's knee alone.

Does painless clicking mean the knee is damaged?

NHS guidance distinguishes normal painless clicking from painful clicking, locking or giving way. Our joint-sounds guide explains what to report during assessment.
