Patellofemoral jt. Flashcards
believed to be a softening or fissuring of the underside of patella
Patellofemoral pain syndrome. PFPS
demographics of PFPS?
mostly in 12-17 y/o
Woman>men
Obesity is a risk factor
different than PFJ OA
Symptoms of PFPS
Anterior knee pain
pain with stairs, squatting,and STS
In relation to patella alta, The femoral groove provides what?
a stabilizing force to patella
happens more often with patella alta
in relation to trochlear mechanics, a decrease in height of lateral femoral condyle or shallow femoral groove cause what?
compressive forces on underside of patella
what are the 2 patellar malalignments?
patella alta
trochlear morphology
patella tracking is largely influenced by ______
bony geometry and position of patella in trochlear groove.
What does an increase in q angle cause?
theoretically
a bowstring effect of quad tending causing patella to track laterally.
What is theory of correcting Q angle?
strengthen VMO
What are the positional faults of patella?
how are they treated?
med/lat tilt/glide/rotated
ant/post tilt
taping. (medial works best)
Can you isolate VMO
whats best way to address PFPS
vm-NOOO
quad strengthening/ exercise therapy.
tight quads or ITB causes what
compressive force in PFJ.
What does tight hamstrings cause?
quads contract harder to compensate increases compressive force.
hip musclular weakness for PFPS, you should use
hip extension/abd muscle retraining to reduce functional valgus
What are the proximal and distal factors of PFPS?
proximal: Hip weakness
Distal:altered foot mechanics
