Patellofemoral Pain

Question 1

Dysplasia

Answer 1

Bad formation

general term used to describe atypical development of any tissue type, usually instability

Question 2

Patellofemoral Joint Pain

Answer 2

diffuse pain over the anterior aspect of the knee

Question 3

Activities that can increase PFJ contact

Answer 3

squatting
stairs
prolonged sitting
repetitive activities such as running

Question 4

Common groups with PFP

Answer 4

gender: females
Age: 12-17, can be any age though
Occupation: military, cyclists

Question 5

Risk factors for PFP

Answer 5

quads weakness
stronger hip abduction
high level of anxiety/depression
fear of movement/catastrophizing

Question 6

NOT risk factors for PFP

Answer 6

age
height
weight
BMI
Q-angle

Question 7

What structures are potential sources of nociceptive input?

Answer 7

1. increased water content in subchondral patellar bone
2. retinaculum and ligamentous structures
3. infrapatellar fat pad

Question 8

PFJ Contact Areas

Answer 8

In relation to femur

0° = femur contact above joint
30° = small area proximal
60° = medium area, medial
90° = large area, distal
120° = small areas, distal

Question 9

What is a structure in the knee region that does not influence PFP?

Answer 9

Q angle is not a risk factor

Question 10

What are structures in the knee region that do influence PFP?

Answer 10

sulcus angle
inclination of lateral anterior femoral condyle
height of patella within trochlear groove

Question 11

Which trunk factors relate to the development of PFP?

Answer 11

1. excessive hip adduction an/or IR
2. Hip extension moments were reduced in pts with PFP during running
3. glute med activation is delayed and shorter duration
4. Possible contralateral pelvic drop

Question 12

PFP and Foot

Answer 12

pts with PFP use more of their available rearfoot eversion during gait

Question 13

Recommended Training for PFP

Answer 13

Exercise Therapy
Spatiotempral Training
Functional Movement Training

Question 14

Exercise Therapy

Answer 14

Duration: better long-term relief seen > 8-12 weeks of therapy vs shorter episodes of care

Intensity: progression from light weight resistance to body weight

Motion deficits: address all

Pt education: help for motor control and diminish fear

Question 15

Running with an increased step rate

Answer 15

decreases peak hip adduction angle
decrease hip abduction moment during stance phase
increased glut medius activity during terminal swing

Question 16

What decreases pressure and contact area of PFJ?

Answer 16

increased step rate

Question 17

Is patellofemoral pain self-limiting?

Answer 17

NO

Question 18

Cue to control valgus moment at knee

Answer 18

keep knee to the outside
don’t let your knee collapse to the inside

Answer 19

mini-squat
isometrics
wall squat
squat to chair

Question 20

Subacute phase for PFP

Answer 20

body weight
ball squats
squat with band

Question 21

Return to function PFP

Answer 21

jump squat
box jumps
split squat jumps

Question 22

Modifications for PFP exercises

Answer 22

unload body weight
elevate heels
rear leg elevate split squat
