16
Q

what is the patient positioning for a lateral/rolled knee

in terms of the knee flexure and what things need to be parallel to the table

A

flex knee 20-30*

pad under the heel so tib/fib and femur are parallel to the table

17
Q

for a lateral/rolled knee what shows no rotation

A

patella in profile

18
Q

for a lateral/rolled knee what joint space is needed and what needs to be superimposed

A

patellofemoral joint needs to be open

femoral condyles superimposed

19
Q

what is the image critique for the lateral/rolled knee view in terms of the positioning

in terms of what 4 things need to be superimposed, the patella and the femoral condyles

A

tibia superimposes 1/2 fibula head

posterior and distal borders of femoral condyles superimposed

patella in profile and patellofemoral joint space open

20
Q

what is the area of interest for knee views

A

distal femur to proximal tibia and fibula

21
Q

what is the CP for lateral hori-ray knee view

A

perpendicular to the knee joint

1.5-2cm distal to the patella apex

22
Q

what kind of lateral is the lateral hori-ray knee

A

lateromedial

23
Q

what is the patient positioning for the lateral hori-ray knee

in terms of affected knee flexion, sponge use, detector placement

A

affected knee flexed 20*

45* sponge pad under knee

IR against medial knee running parallel to the affected leg

24
Q

what is the AP weight bearing knee view used to assess

in terms of anatomy and pathology

A

knee joint, distal femur, proximal tibia/fibula and patella

evaluates OA

25
Q

what is the patient positioning for the AP weightbearing knee view

in terms of the detector and knee rotation

A

both knees imaged

patient erect against upright IR with knee and ankle joint in contact with IR

knees un-rotated (sometimes need to turn the toes in)

26
Q

what is the patient positioning for the skyline knee view

in terms of knee position and what the 2 places are that the detector could be placed at

A

knees flexed

IR at patients heels or against their knee

27
Q

what is the CP for the skyline knee view when the detector is at the heels

A

angled IR to patellofemoral joint space

detector at heels = 30* (to femur) caudal

28
Q

what is the CP for the skyline knee view when the detector is at the knees

A

angled IR to patellofemoral joint space

detector at knees = 10-15* from horizontal, tangential to patella
