Movement Notes — Pilates on George — by Olya Kudryavtseva
Patellofemoral pain (PFP) is pain around or behind the kneecap, typically aggravated by squats, stairs, and prolonged sitting. Imaging usually shows nothing structural. The 2018 international consensus statement confirms hip and knee strengthening combined is more effective than knee-only programs. The knee is downstream but the work is upstream.

The research has been telling us for years that’s the wrong place to look.
What Is Patellofemoral Pain (PFP)?
PFP is pain around or behind the patella (kneecap), typically aggravated by loading the knee in flexion: squats, stairs, hills, prolonged sitting (the “theatre sign”). It’s not a single pathology. It’s a clinical pattern that can have multiple contributors.
What it usually isn’t found: structural cartilage damage. Imaging studies show that chondral findings correlate weakly with symptoms. Many people with bone-on-bone changes have no pain. Many people with severe pain have unremarkable imaging.
How the Patellofemoral Joint Actually Works
The patella sits in the trochlear groove of the femur which is a shallow channel on the front of the thighbone. The quadriceps tendon attaches above it, the patellar tendon below. The patella tracks through this groove during knee flexion and extension.
Its position is influenced by quadriceps balance, femoral rotation, tibial position, and foot mechanics. The patella isn’t working on its own – it goes where the femur and tibia tell it to go.
What Causes Patellofemoral Pain?
Powers et al. (2010) demonstrated through 3D motion analysis why hip mechanics matter so much. The knee’s position in space is determined more by hip and foot mechanics than by anything happening locally. If the femur internally rotates and adducts (knee falling inward), the patella tracks poorly relative to the femur, even if the patella itself isn’t doing anything wrong.
Common contributors:
• Hip abductor weakness: gluteus medius can’t control femoral adduction during single-leg loading
• Hip external rotator weakness: femur internally rotates under load, dragging the trochlea away from the patella
• Foot pronation: excessive subtalar pronation can drive tibial internal rotation, which the knee absorbs
• Quadriceps tightness or weakness: still relevant, just not in the VMO-isolation way
What Does the Research Say About Treating PFP?
The 2018 International Patellofemoral Pain Research Retreat consensus statement summarised the evidence. Key points:
• Hip and knee strengthening combined is more effective than knee-only programs
• Vastus medialis oblique (VMO) selective activation – the holy grail of 1990s knee rehab is not actually achievable. The quad fires as a unit.
• Patellar taping and orthoses can give short-term relief but don’t replace strength work
• Outcomes correlate with hip abductor and external rotator strength gains
What Exercises Help Patellofemoral Pain?
• Hip strength first: abductors, external rotators, extensors. Side-lying leg series, standing single-leg work, banded clamshells with progression.
• Squat mechanics – watch knee tracking. If it falls inward under load, that’s where the work is — not in avoiding the squat.
• Foot work – intrinsic foot strength, controlled pronation/supination work.
• Load the knee – don’t avoid flexion forever. Capacity is built by progressive loading. Pain that subsides quickly after activity is acceptable; pain that escalates needs dose reduction.
Frequently Asked Questions
Are squats bad for patellofemoral pain?
Not necessarily. Avoiding squats long-term often makes things worse. What matters is squat mechanics, particularly that the knee doesn’t fall inward under load, and the dose. Pain that settles within 24 hours of squatting is generally acceptable.
What’s the best exercise for runner’s knee?
The strongest evidence supports hip strengthening, particularly abductors (gluteus medius) and external rotators, combined with progressive knee loading. Single exercises aren’t the answer; a combined program over 6–12 weeks is.
Should I avoid stairs with patellofemoral pain?
Reduce dose if symptoms are severe, but don’t avoid completely. Stairs are often used as a marker of progress in PFP rehab: the goal is to gradually rebuild tolerance, not avoid permanently.
Can Pilates help knee pain?
Yes! Pilates is particularly suited to PFP rehab because it allows precise control of load and excellent training of the hip and core musculature that supports the knee. Our Sydney CBD studio works with many clients managing knee pain.
How long does patellofemoral pain take to heal?
Most cases improve significantly within 6–12 weeks of consistent strengthening, though full recovery and return to all activities can take 3–6 months. Patience with the progression matters.
The Bottom Line
When the knee complains, look what is above it. The body rarely tells you where the problem is, only where the symptom is.
PFP is one of the clearest examples of why a whole-body movement approach matters. The knee will follow what the rest of the body teaches it. Teach it well.
