MAII: knee Flashcards
MA II: knee
normal knee angle (lateral)
170-175
less than 165 = genu valgum
more than 180 = genu varum
MA II: knee
ACL becomes increasingly taut as the knee approaches and reaches full
extension
MA II: knee
Other functions of the PCL include acting as a secondary restraint to ______ of the tibia on the femur at 90 degrees of flexion
external rotation
MA II: knee
Other functions of the PCL include acting as a secondary restraint to ______ of the tibia on the femur at 90 degrees of flexion
external rotation
MA II: knee
As the knee extends toward 90 degrees of flexion, the primary contact region on the patella starts to migrate toward its…
inferior pole
MA II: knee
Both the ACL and PCL lie in the center of the joint, and each is named according to
their attachment sites on the tibia
MA II: knee
in open chain motions, the patella
slides on intercondylar groove of the femur
MA II: knee
Menisci are avascular except
the outer 1/3 or perifery
MA II: knee
As the knee extends through the last 20 to 30 degrees of flexion, the primary contact point on the patella migrates to its
inferior pole
MA II: knee
Because of the bony attachment of the patellar tendon to the tibial tuberosity, the patella follows the direction of the_____ during knee flexion
tibia
MA II: knee
The quadriceps (Q) angle can be described as the angle formed by the bisection of two lines, one line drawn from __________________, and the other line drawn from ____________________________ .
- the ASIS to the center of the patella
- the center of the patella to the tibial tubercle
MA II: knee
MCL provides the primary restraint for ______ and lateral rotation of the tibia, and is a secondary restraint to anterior and posterior translation of the tibia on the femur.
valgus
MA II: knee
Medial meniscus is C-shaped; it’s external border attaches to
MCL
MA II: knee
Lateral meniscus is circular shape and attaches only to
the lateral capsule
