T/ F Questions
“Patellofemoral pain” is one of the most common musculoskeletal diagnoses.
Patellofemoral pain is a complex, multifactorial problem.
T/ F Questions
Patellofemoral pain responds reliably well to rehabilitation.
Certified Athletic Trainers and Physical
Therapists provide rehabilitation.
T/ F Questions
The ideal rehabilitation program for a complex, multifactorial problem like patellofemoral pain is hard to define.
“Genius” is hard to define.
Therefore…..
Athletic Trainers and
Physical Therapists are geniuses!!
Thank you.
The evolution of a clinician…..
“So what is our patellofemoral pain protocol?”
“We don’t have ONE. We’ll never have one. No two
PFPS rehabilitations are the same.”
Uh oh, first sign of trouble …..
Midterm time…..M/C
Which of these people has PF pain?
Midterm Time…...Short Answer
When rehabilitating/ requesting rehabilitation for someone with PF pain, I most often utilize/ request…….? (List your top 3)
Top 3 ?
Quad strengthening
VMO facilitation
Stretching (based upon need)
Quadriceps
Lateral structures
Hamstrings
Posterior calf (Soleus)
Hip abductor strengthening
Taping/ Bracing
Arch supports
When the PT’s “cover” clinic….
Referral hangs outside door
Evaluate and Treat
Evaluate and Return to IOSMR
Evaluate and Coordinate with PT close to home

Evaluation AND Treatment

Tools in the toolbox
Timing and rationale → and dosing → and “buy in”
The evolution of a clinician……
Evaluation
Observation
Foot position, Tibial varum, leg length, atrophy
Palpation
Patellar position, patellar tracking, quadriceps “tone”
ROM (Flexibility)
Quad, Hamstrings, “lateral structures” , calf
Strength
SLR x 3, Quads- No
Functional
Squat, Lunges (Stacy V)
The evolution of a clinician…….
Now, for PFPS, just treatment
“Pattern recognition”
Assumptions
Focused treatment
Treatment guides eval
Treatment Approach for PFPS
Phase 1
Everyone gets QS/ SLR x 4
And some stretching
“It may not be exactly right, but it’s never wrong”
“Get on base, don’t swing for the fence”
Phase 2
“Groucho Marx” Therapy
“Hey doc it hurts when I do this.”
Ok let’s do that or something similar
Phase 3
Return to activity
Phase 4
Long term plan
Best Case Scenario
Visit 1
QS, SLR, Stretching, Wall Sits
Visit 2 (1 week later)
30-50% better
Step ups
Isotonics (ham curls, light leg press, hip)
Visit 3 (1 week- 2 weeks later)
~ 70% better
CV Exercises
Talk about progression to running (prn)
Visit 4 (3-4 weeks after I/E)
“How’s running going?”……OK great, here’s how to progress your HEP, have a nice life
Rule of 70’s
“at least 70% of patients will feel at least
70% better within 2-3 weeks of starting rehabilitation”
The remaining 30% …….
The tale of Roy McAvoy
“I can make that shot”
“I know you can, but not right now”
You’re in good shape after 2…..
but you’re staring at a 12
PFPS History Lesson Part 1
My summary of 20 years of PFPS PT Rx. Lit.
Because most patients improve with PT, it is unethical (maybe “unthinkable”) to include a control group
2 treatment groups
Both improve
Equally!!.....arrrgh
VMO Facil., OKC vs. CKC, Conc. Vs. Ecc. ,
Taping vs. Bracing, Bracing vs. Orthotics

Supervised Rehab vs.
Info + HEP (“standard care”)
9 visits over 6 weeks
Progressive resistance every 2 weeks
Quadriceps, Adductors, Gluteal strengthening
Stretching
Balance
“Improved” but not “recovered”
Are they “needy” or “kneedy”

VMO Weakness
Quad strengthening
VMO Facilitation
Differences in timing of VMO / VL – PFPS vs. non.
Just one more risk factor
McConnell’s Critical Test / Taping
Just tape it
When the foot hits the ground …..must control the midfoot
Try some OTC inserts
But the results are stable……the understanding is not
“So what is our patellofemoral pain protocol?”
“We’re not sure, but patients keep getting better anyway”.

October is National PT Month
Happy PT Month!!
Just in case you were interested….
The green lining perhaps
Supervised Rehab (9 visits/ 6 weeks vs. Info + HEP
Where do we go from here?
“PFPS School ” at CRWC
Women aged 18-50
Information
Anatomy, Epidemiology, Natural History (young woman’s disease)
Exercise
Stretching (Q, H, C, Lateral)
Strengthening (Quads, Hip adductors/ abductors)
Instruction for taping (kinesiotaping)
Encouragement
Keep exercising
Call us if
Sx. not at least 50% better after 4 weeks
“Other” groups
Level 6 Evidence – One guy’s opinion
Men with CMP- Stretching!
Patellar Tendonitis – Eccentrics, Aggressive quadriceps and hip abductor strengthening
UI athletes with CMP-
Muscle Imbalances -
Full, Static and Dynamic Eval
Address specific imbalances – specific exercises
Remember where you are “in season”- set expectations accordingly
Don’t assume strong quadriceps (if you only have 1 bullet)
Thank You.

Can you selectively train the VMO?
“….it would appear that isolated recruitment or strengthening of the VMO through selected exercises may not be a realistic goal and any emphasis on selective strengthening of the
VMO would most likely translate into a general quadriceps strengthening program.”
