Patellofemoral Pain Syndrome (PFPS) is one of the most common knee issues we see at Physio On The Green — especially in runners, cyclists, gym-goers, and anyone who loads their legs heavily. Despite this, it remains one of the most misunderstood injuries. It’s often labelled as “just a bit of kneecap pain” or “overuse,” but that massively undersells what’s really going on.
PFPS isn’t a single diagnosis. It’s a biomechanical overload problem involving the patella (kneecap), femur, soft tissues, and the way you move. And with the right assessment and tailored rehab, it is absolutely treatable.
What Exactly Is Patellofemoral Pain Syndrome?
PFPS is irritation of the joint between the kneecap and the femur. When forces exceed what the joint can comfortably tolerate, you get symptoms such as:
- Pain around or behind the kneecap
- Clicking or grinding
- Pain going downstairs
- Discomfort after sitting
- Pain during running or cycling
- A feeling of “weakness” or instability
For performance athletes, this often shows up when training volume spikes, movement patterns change, or strength imbalances creep in.
Why Active People Get PFPS
- Quad overload vs Quad under-load, both can trigger it: Classic runner’s knee often emerges when the quadriceps muscles are either doing too much (tight, fatigued, overloaded) or too little (weak, slow to engage, lacking force).
- Poor force distribution through the hip and ankle: If the hip abductors aren’t doing their job, the thigh rotates inward, changing the tracking of the kneecap. Cycles are especially prone to this due to long hours spent in flexion.
- Poor shock absorption: When your tissues can’t manage load, the patellofemoral joint becomes the bottleneck.
- Rapid load spikes: A common pattern: “Felt fine → increased mileage → knee starts complaining.”
The joint often struggles with pace or elevation changes (downhill, intervals, sprints).
How We Diagnose Patellofemoral Pain at Physio On The Green
PFPS requires a gold-standard assessment — not a quick poke and hope.
At Physio On The Green, you get:
- Diagnostic Ultrasound (where appropriate) helps us evaluate the fat pad, tendon, bursal structures, cartilage irregularities, and rule out other causes of anterior knee pain.
- VALD ForceDecks Performance Testing. This is a game-changer. We objectively measure:
- Quad vs hip strength
- Left-right asymmetry
- Rate of force development
- Landing mechanics
- Knee Dominant vs hip-dominant loading
These data shine a light on WHY your knee hurts – not just WHERE.
- Biomechanical Assessment: Running Gait analysis, squat mechanics, single-leg strength, foot control, and cycling set-up (if relevant).
- Training load review: We map your mileage, intensity, and cadence to understand your stress picture.
Treatment: What Actually Works (Evidence + Performance Focus)
- Strength training (the cornerstone): Targeted loading makes tissues more resilient. We build progressive strength through:
- Quads
- Hip abductors
- Hip external rotators
- Hamstrings
- Calves
But the magic is in the dosage – sets, reps, tempo, and weekly training load all matter.
- Patellofemoral-friendly modifications: Sometimes adjusting exercise angles (e.g., forward-lean squats) massively reduces pain.
- Running & cycling technique and coaching: We tweak cadence, posture, foot strike, or saddle height depending on the athlete.
- Soft tissue, taping and manual therapy: Useful for reducing short-term sensitivity.
- Injection options: In persistently irritable cases, ultrasound-guided injections can help you tolerate your rehab and allow you to build a foundation upon.
How Long Until It Gets Better?
With a structured rehab plan, many people improve within 6–12 weeks.
Elite athletes or chronic cases may take longer, but progress is consistent when training load and strength work are aligned.
When to See a Physiotherapist
Seek help if:
- Your knee pain lasts >2 weeks
- Pain limits running, cycling or sport
- Sitting becomes painful
- You’re avoiding downhill or stairs
- You’ve tried generic strengthening with no improvement
PFPS rarely “just goes away” on its own – but it responds brilliantly to the right plan.
