Patellofemoral pain syndrome
Summary
Definition
History and exam
Key diagnostic factors
- ill-defined ache
- pain aggravated by compressive force
- Q angle
- pain on palpation of patellar retinaculum
- patellar tilt test
- mediolateral glide test
- patellar mobility test
- patellar apprehension test
- patellar maltracking test
- decreased muscle flexibility
- muscle weakness
Risk factors
- bony and structural abnormalities
- iliotibial band tightness
- abnormal patellar mobility
- quadriceps muscle weakness
- subtalar joint pronation
- hip internal rotation
- gait deviations
Diagnostic investigations
1st investigations to order
- no initial test
Investigations to consider
- knee x-ray
- MRI
- kinematic MRI or CT
Treatment algorithm
acute pain
abnormal patellofemoral joint mechanics
lower kinetic chain problems
overuse in athletes
post initial and reactivation-phase treatment
