What is the weight bearing bone of the lower leg?
Tibia
The proximal end of the tibia slopes posteriorly how many degrees?
10 - 20 degrees
Separation of the tibial tuberosity from the body of the tibia is called?
Osgood-Schlatter’s Disease
Most commonly in boys ages 10-15
The lateral malleolus lies how many degrees more posterior than the medial malleolus?
15 - 20 degrees
The apex of the patella lies where?
Lies 1/2 inch above the knee joint
Patella articulates with what bone(s)?
Only articulates with the femur
The largest and strongest bone in the body is?
Femur
The medial condyle of the femur extends lower than the lateral condyle by how many degrees?
5 - 7 degrees
Intercondylar Sulcus is another name for?
Patellar Surface/Anterior Surface of the femur
Adductor Tubercle is located where?
Located on the posterolateral aspect of the medial condyle of the distal femur

*This is the main joint of the knee
What ligaments stabalize and attach to the intercondylar eminence of the knee?
Cruciate Ligaments
*Restricts anterior and posterior movement
What ligaments restrict adduction and abduction movements of the knee?
Collateral Ligaments
What is the largest joint space in the body?
Knee Joint
What acts as shock absorbers in the knee?
Menisci
What is used to visualize a torn meniscus?
MRI or Knee Arthrogram
If the knee is clipped for a Tib/Fib what should be done to complete the exam?
Shoot an additional AP Knee
True or False.
A fracture of the distal tibia can indicate a fracture of the proximal fibula?
True
What projection best shows the patella towards the tibia?
Medial Oblique Knee
The mediolateral knee projection has a 5-7 degree cephalic angle; where is the CR placed at?
1 inch distal to the medial epicondyle
* Knee is flexed at 20 - 30 degrees
Once the tube angle matches the leg for an Axial Patella projection, the tube then decrease by what?
The tube decrease (Caudally) by 15 - 20 degrees
What projection will provide good visualization of a vertical fracture of the patella?
Axial Patella ( Sunrise, Sunset, Settegast, Skyline)
