Graded A+
Snynovial fluid - provides nutrition for the articular cartilage
osteophytes - outgrowth of bone aka bone spur
Medial tibiofemoral - the inside of the knee
Lateral tibiofemoral - outside of the tibia on the knee
Patellofemoral - Under the patella
Front view of the knee - AP view (Anterior posterior view)
Side view of the knee - Lateral view
Back view of the knee - Oblique view
Medial Collateral ligament - Inside ligament that goes outside of the knee
Lateral collateral ligament - outside ligament that goes outside of the knee
What do the medial and lateral collateral ligaments do? - Provides stability to the knee
in the coronal plane
The medial collateral ligament is the largest and - Strongest of the collateral ligaments.
The lateral collateral ligament attaches - Posterior femoral condyle and fibular head
The medial collateral ligament origin is - the medial femoral epicondyle and attaches to
the medial tibial condyle
ACL is - the major ligament that regulates anterior tibial translation
PCL - Posterior tibial translation control
-lower attachment to tibia
Menisci - Disperses body weight
reduces friction
provides stability.
What is the thickest cartilage in the body - patella articular cartilage
The capsule attaches to - The femur and tibia to provide fluid sack. (Snynovial fluid)
Extensor mechanism - Quadriceps muscles.
, -connects to the patellofemoral joint
Flexion mechanism - Hamstrings.
The hamstring contains what 3 muscles? - Biceps femoris
semimembranosus
semitendinosus
Knee anatomy -
What 4 bones is in the knee - Femur, tibia, fibula, patella
What 3 joints are in the knee - The medial tibiofemoral
lateral tibiofemoral
patellofemoral
Anatomical Axes of the knee - A line drawn down the center of the medullary cavity of
the bone.
Mechanical Axes of the knee - Axis of weight bearing in the lower limb.
drawn from the center of the femoral head, to the center of the knee and center of the
ankle
Varus - Bowlegged
Valgus - Knock knees
Which is stronger the LCL or the MCL? - The MCL
6 degrees of motion present in the human knee -
When the femoral is bent, what way does the roll back contact point go? - More
posterior
The axis of rotation changed throughout the degree of flexion - J curve or better now a
days as the C curve
MCL and PCL work together on the - Medial side with minimal motion
LCL and ACL work together on the - lateral side to accommodate sliding
What are the 3 arcs of motion? - Screwhome arc, Functional arc, deep flexion arc.
Screwhome - As the knee flexes from -5 extension to 10 flexion.
Flex and lock
- Passive motion.
