41
What 2 joints make up the Knee Joint?
Tibiofemoral and Patellofemoral Joint
42
What kind of bone is the patella?
Sesamoid bone
43
As the tibiofemoral joint flexes,
stress at the patellofemoral joint increases
44
Another name for Medial Collateral ligament?
Tibial collateral ligament
45
Another name for the lateral collateral ligament?
Fibular collateral ligament
46
What 2 things does the Anterior cruciate ligament do?
-Keeps the tibia from sliding forward -Helps control and limit rotation
47
What group of dynamic stabilizers help the ACL?
The hamstrings
48
What happens when the hamstrings concentrically contract?
They move the tibia backwards
49
What 2 things does the Posterior cruciate ligament do?
-prevent tibia from sliding backwards -prevents, reduces, and controls rotation
50
What group of dynamic stabilizers help the PCL?
The quads
51
What happens when the quads concentrically contract?
they move the tibia forwards
52
There is a medial and lateral one of these AND it is considered fibrocartilage?
Menisci
53
How many menisci are there?
4; 2 in both knees
54
Both Menisci are attached to the tibia in 2 places, where is that?
The anterior and posterior horn
55
Anterior cruciate ligament
ACL
56
Posterior cruciate ligament
PCL
57
Medial collateral ligament
MCL
58
Laterla collateral ligament
LCL
59
Suprapateller bursa
Between femur and quads tendon
60
Infrapatellar bursa
Between tibia and patella tendon
61
Subcutaneous prepatellar bursa

62
Bursar is a ?
Shock absorber and reduces friction
63
Knee flexion
140 degrees
64
Knee extension
0 degrees (10 degrees of hyper extension)
65
Screw home mechanism
In order for the knee to fully extend, it has to externally rotate (v. medialis) In order for the knee to flex, it has to internally rotate (popliteus)
66
