What is a runner's knee?

Runner’s knee, also known as patellofemoral pain syndrome (PFPS), refers to pain around the front of the knee or kneecap. It’s one of the most common overuse injuries among runners and athletes.

Runner’s knee symptoms

• Pain during activities like running, squatting, or climbing stairs.
• Swelling around the kneecap.
• A grinding or clicking sensation when bending the knee.

What causes a runner's knee?

• Overuse: Repeated stress from high-impact activities.
• Weak muscles: Insufficient strength in the hips, glutes, or quads.
• Poor running form: Misalignment can strain the knee.
• Improper shoes: Wearing worn-out or unsupportive shoes exacerbates the issue.
• Sudden activity changes: Rapidly increasing mileage or intensity without proper adaptation.

How do I test if I have a runner's knee?

If you’re experiencing knee pain, here are some signs to check for runner’s knee:

• Activity-specific pain: Notice discomfort when squatting, climbing stairs, or after long runs.
• Kneecap sensitivity: Press gently around the kneecap. If it’s tender, you may have PFPS.
• Stiffness after sitting: Pain or stiffness after prolonged sitting can also indicate runner’s knee.

Pro tip: If your pain persists or worsens, consult a healthcare provider for an accurate diagnosis and treatment plan.

Where does the runner's knee hurt?

Runner’s knee typically causes discomfort in the following areas:



• Around the kneecap: Pain may occur at the front or sides of the kneecap.
• Behind the kneecap: Grinding sensations or deep aches may originate here.
• Surrounding tissues: Swelling or tightness around the knee joint.

How to prevent runner’s knee

Preventing runner’s knee is easier than treating it. By focusing on proper form, strength training, and recovery, you can reduce your risk of injury.

Warm-ups and cool-downs

Always start your runs with a dynamic warm-up to prepare your muscles and end with a cool-down to aid recovery. Simple movements like leg swings and lunges can go a long way in reducing strain on your knees.

Strengthening exercises

Incorporate cross-training activities like cycling or yoga to strengthen supporting muscles and improve flexibility.

Proper footwear

Wearing the right running shoes can make all the difference. Replace shoes every 300–500 miles to ensure proper cushioning and support. For guidance, check out our blog on the best marathon shoes.

Gradual training progression

Avoid rapidly increasing your mileage or intensity. Follow the 10% rule: increase your weekly mileage by no more than 10% to give your body time to adapt.

How long does a runner's knee last?

Recovery from runner’s knee varies based on severity and treatment:

• Mild cases: Pain may subside within a few days to a week with rest and care.
• Moderate cases: Recovery can take 4–6 weeks with consistent rehabilitation.
• Severe cases: May require several months and professional intervention.

What does a runner's knee feel like?

Runner’s knee can manifest in various ways:

• Dull ache: Persistent pain around or behind the kneecap.
• Sharp twinges: Sudden pain during activities like squats or stairs.
• Grinding sensation: A feeling of grinding or popping when bending the knee.

Emotionally, runner’s knee can be discouraging, especially when it disrupts training plans. However, with patience and the right care, you can overcome it.

Tips for managing runner’s knee during training

Dealing with a runner's knee doesn’t mean you have to give up running altogether. Here’s how to manage it while staying active:

1. Modify your training: Reduce mileage and avoid high-impact activities until your knee heals.
2. Low-impact alternatives: Swap running for swimming or cycling to maintain fitness.
3. Gradual return: Ease back into running by starting with shorter distances and slower paces. Change the running surface like a track or the treadmill to reduce impact
4. Track your progress: Use a running watch to monitor your recovery and ensure you’re not overloading your knees.

Pro tip: Listen to your body and stop immediately if pain worsens.

Top tools for preventing and recovering from runner’s knee

• Foam rollers: Relieve tight muscles and improve flexibility. Example: TriggerPoint GRID Foam Roller. 
• Compression sleeves: Support healing and reduce inflammation. Example: Pro-Tec Athletics Knee Sleeve. 
• Running shoes: Minimize knee impact with cushioned shoes. Example: Hoka Bondi 8
• Massage balls: Target deep muscle knots for improved mobility. Example: RAD Massage Ball.
