What are the three articulations of the knee joint?
Medial femerotibial
Lateral femerotibial
Fermeropatellar
Which bone is not part of the knee joint?
The fibular
Why does vastus medialis pull at a much more oblique angle than the other three quads?
to prevent the patella being pulled too laterally
What is the name for an injury in which a body structure is forcibly detached from its normal point of insertion by trauma or surgery?
Avulsion
What are menisci?
Interarticular discs of fibrocartilage in the knee joint
What are the menisci in contact with?
The superior articular surfaces of the lateral and medial condyle
How many menisci are there in the knee joint?
2, one medial, one lateral
Which menisci is more mobile?
The lateral menisci - it is unattached to knee joint
How do the menisci connect to the knee?
By the transverse ligament
How many intrinsic ligaments of the knee are there?
3 - Patella ligament, Cruciate ligament, Collateral ligament
What is the patella ligament a continuation of?
The quadriceps femurs tendon
How many cruciate ligaments are there?
2 - one anterior, one posterior
Which ligament attaches to the lateral condylar of femur?
Anterior cruciate ligament
Which ligament attaches to the medial condylar of femur?
Posterior cruciate ligament
How many collateral ligaments are there?
2 - one on each side of the hinge joint
Which collateral ligament attaches to the lateral femoral epicondyle?
Fibular collateral
Which collateral ligament attaches to the medial femoral epicondyle?
Tibia collateral
What produces extensions at the knee joint?
Produced by quadriceps femoris
What muscles produce flexion of the knee?

What passes through the saphenous hiatus (opening in deep fascia)?
The long saphenous vein
Where does the long saphenous vein originate?
The dorsal venous arch of the foot and the dorsal vein of great toe
What vein does the saphenous vein join in the femoral triangle?
The femoral vein
What forms the base of the femoral triangle?
The inguinal ligament
What forms the medial margin of the femoral triangle?
Adductor longus - medial margin
What forms the lateral margin of the femoral triangle?
Sartorius - medial margin
Which muscles form the floor of the femoral triangle?
Pectineus and adductor longs medially
Iliopsoas laterally
Name the contents of the femoral triangle?
Femoral artery and vein
Femoral nerve
Femoral canal - contains deep lymph nodes and vessels
Which content of the femoral triangle is not contained within the femoral sheath?
The femoral nerve
What carries the femoral vessels, nerve to vastus medialis,saphenous nerve between the femoral triangle and popliteal fossa?
Adductor canal
What is the anterior border of the adductor canal?
Sartorius
What forms the posterior border of the adductor canal?
Adductor longs and adductor magnus
What forms the lateral border of the adductor canal?
Vastus medialis
What is the main function of the muscles of the medial compartment of the thigh?
Adducts the thigh at hip joint
Where is the adductor hiatus located?
In adductor magnus muscle - between muscle and femur
What passes through the adductor hiatus?
The femoral artery - becomes the popliteal artery
