Pathology 7 - MSK Flashcards
(47 cards)
Patellofemoral Syndrome - what is it
pain or discomfort in the anterior knee
Patellofemoral Syndrome - other term
chondromalacia patella
Patellofemoral Syndrome - is due to what
rep overuse disorder resulting from the increased force at the patellafemoral joint
abnormal tracking of the patella between the femoral condyles - leads to misdirected forces between the patella and the femur
Patellofemoral Syndrome - factors assiociated with increase patellofemoral force include
decreased quad strength - vastus medialis
decreased LE flexibility - quads, hamsrings, gastroc, iliopsoas
patellar instability
increased tibial torsion or femoral anterversion
excessive pronation
knee valgus
femoral anteversion and tibial torsion
internal tibial torsion - IR
Patellofemoral Syndrome - risk factors
increase sport participation
females
growth spurt
overweight
runner who have recently increased their milage
Patellofemoral Syndrome - electromyography based feedback
should be avoids to augment Vastus medialis actvity
what is electromyography based feedback
EMG
based feedback is a technique that uses electrodes to record and display muscle activity in real time
Patellofemoral Syndrome - visual feed back
should be avoid when trying to correct leg alignment
Patellofemoral Syndrome - biophysical agents
US, cyrotherapy, phonophoresus, iontophorese, ESTIM
should be avoided
Patellofemoral Syndrome - what is normally happening to the patella during knee extenion
the patella is being pulled too laterally
Patellofemoral Syndrome - older population
normally associated with OA
Patellofemoral Syndrome - signs and sym
gradual onset of anterior knee pain - increase in activity
retropetellar pain
worse with activity that increae patella femoral force - flexion - and static positioning
point tenderness of the lateral border of the patella
crepitus
visable quad atrophy - vastus med
what is retro-patellar
behind the patella
does medial or lateral glide normally help pt with PFPS
medial glide
the lateral structure are normally tight
PFPS is seen most with what kind of sports
jumping sports
Piriformis Syndrome - physiological causes
compressive irration to the proximal sciatic nerve 2/2 the prirformis muscle inflammation, spasm, or contracture
Piriformis Syndrome - is a common etiology of what
low back pain
what is etiology
the cause of a disease
what is the function of the piriformis
abd and ER the hip
Piriformis Syndrome - external causes
trauma
abnormal gait mechanics
lumbar lordosis
periods of long sitting
Physical activity participation
Piriformis Syndrome - clinical presentation
local of pain in imprecise - midbutt area and progress to radicular complaints in the sciatic nerve distribution
Piriformis Syndrome - sym are normally exberated with what position
prolonged sitting
activities that combine add and medial and IR or the hip
Piriformis Syndrome - pain reproduction
palpation
resistance testing during lateral rotation and abd
radicular sym increased with SLR and decreased with traction of the LE
