PFP Flashcards
How is PFP diagnosed? (5 things)
Pain under or around the patella with functional activities such as stair climbing, squatting, sport participation, prolonged sitting and walking
True or false: PFP patients are more likely to end up with patellofemoral OA.
False
What are the factors that are related to PFP? What are surprisingly not associated with PFP
Are related: female sex, sport specialization, decreased knee isometric strength.
Are not; q angle, BMI, patella mobility, static knee Valgus
To prevent PFP you want to (3 things)
Educate females to participate in a variety of sports and for exercises to improve knee extension strength
These items show up with PFP but are not predictive
Weakness of hip extensors, ER and abductors, decreases flexibility of hamstrings, quads and gastroc. Altered mechanics with squatting and stair climbing
What are two hip dx that could act like PFP?
SCFE and hip fx
What is the most specific test for PFP?
Eccentric step down
What are two differences in patellofemoral OA and PFP?
In PF OA you’re looking at increased age and significant loss of knee ROM
What are the four tx categories of PFP
- Overuse and overload without impairment (military or runners)
- PFP with movement coordination deficits (increased dynamic Valgus with movement)
- PFP with muscle coordination deficits (hip and knee weakness)
- PFP with mobility impairments: hypermobility in the foot >11 MM midfoot measure or foot posture score >6 or positive patellar tilt test and decreased LE flexibility
What is the cutoff for hamstring flexibility in PFP?
78* SLR
What is the cutoff for gastroc flexibility for PFP?
7.4*
What is the cutoff for soleus flexibility?
14.8*
What is the cutoff for flexibility of the quads for PFP
Prone knee flexion of 134*
The KOOS PFP MCID is
14.2
What are the three outcome measures to use for PFP
KOOS PFP: 14.2
Kahala akps: 9
Both scored to 100 with higher better function
EPQ which rates pain level with 6 movements
