Knee Flashcards
1
Q
Which has condyles , tibia or femur?
A

2
Q
Which femoral condyle is larger?
A
Medial
3
Q
Are menisci available on plain film?
A
No
4
Q
What does the rosenberg test typically look for?
A
Joint space patho
5
Q
If the femoral condyles arent overlapped near patella then what is the problem?
A
Rotation
6
Q
If the femoral condyles arent overlapped near tibia then what is the problem?
A
Beam angulation
7
Q
LIPOHAEMARTHROSIS
A
The bursa appears expanded and has a darker upper half and a lighter lower half. This is because the fat is less dense than blood and therefore floats on top of the blood and does not absorb as much of the x-ray beam
8
Q
JOINT EFFUSION
A
Joint effusions may occur without a fracture present but fat will not be included in the effusion
9
Q
Two types of knee dislocations
A
patellafemoral
tibiofemoral
10
Q
Patella subluxation
A
Mis tracking or slight dislocation of patella
11
Q
view typically used for patella instability
A
Skyline (axial)
12
Q
Projection typically used for loose bodies in knee joint space
A
Intercondylar
13
Q
FABELLA
A
Accessory ossicle
in the gastronemius
muscle
14
Q
Varus and valgus xray appearance
A
Radiographic Appearance – Decreased joint space – Subchondral bone sclerosis – Joint margin osteophytes – Subchondral cysts
15
Q
OSGOOD SCHLATTER
DISEASE
A
An irritation of the patellar ligament at the tibial tuberosity. • Occurs in active children aged 9–16 coinciding with periods of growth. • Boys > Girls • Caused by stress on the tendon • Multiple subacute avulsion fractures along with inflammation of the tendon, leading to excess bone growth in the tuberosity and producing a visible lump which can be very painful when hit
