Q

Patellofemoral symptoms can be due to:

A

joint reaction forces as well

17
Q

which specific muscle groups should you address activation deificts for pts with PTF pain?

A

quads, hip abductors/lateral rotators, core

18
Q

mechanism of injury of patellar dislocation

A

pivot

19
Q

what is important to note about a patellar dislocation?

what is the most common kind of dislocation

A

it spontaneously relocate

lateral dislocation

20
Q

risk factors that can lead to patellar dislocation

A

increased Q angle, increased femoral anteversion, increased pronation

21
Q

treatments for acute patellar dislocation

A 
aspiration and check for fat globules 
bent knee 
brace 
mcConnel tape 
arthroscopy
22
Q

in order to balance the medial vector, what ligament is there a repair to? malpositions can cause what

A

medial patellofemoral ligament

forces to be distributed differently

23
Q

postop management for medial patellofemoral ligament reconstruction

A

NMES to tape patella medially and stimulate the VM of the quads

24
Q

distal realignment pathologies addressed:

A

lax medial PF ligament
patella alta
increase Q angle
chondral damage

25
Q

what is the curve ball to a patellar realignment?

A

stress fracture at 6-12 weeks due to 50 % pop, ankle swelling, pain at distal incision with varus and valgus stress

26
Q

what does lateral patellar/compresion/facet syndrome affect?

A

causes a tight lateral P-F ligament - primary pathology

27
Q

s/s for lateral patellar compression:

A

lateral patellar facet pain
positive patellar tilt test
worsening with patellar compression activities

28
Q

difference between osgood schlatters disease and sinding-larsen johansson disease.

A

osgood - tenderness/swelling over tibial tubercle

sinding - tenderness/swelling at inferior pole of patella

29

AM stiffness < 30 minutes 
intermittent joint swelling 
bony osteophytes 
joint effusion 
decreased muscle strength, ROM, 
decreased proprioception
33
Q

how does a patella fx occur?
