Answer 3

Trochlear groove

Question 4

What is the groove on the patella called and for?

Answer 4

Articular facet for medial condyle

Question 5

What is on the more inner side of the condyles on the femur and tibia?

Answer 5

Epicondyles

Question 6

What is the function of the patella?

Answer 6

Increases the leverage of the quadriceps at the knee

Question 7

How does the leverage of the patella function?

Answer 7

Creates a longer lever from where the quadriceps are pulling from, thus giving a higher contracting force

Anterior to the patella

Question 11

Where is the Suprapatellar bursa located?

Answer 11

Superior to the patella

Question 12

Where is the infrapatellar bursa located?

Answer 12

Inferior to the patella

Question 13

Where is the tibial plateau?

Answer 13

Superior surface of the tibia

Question 14

What does the tibial plateau do?

Answer 14

Articulates with the lateral condyles to create flexion and extension in a hinge manner

Question 15

Where is the anterior cruciate ligament located?

Answer 15

The posterior medial border of the lateral femoral condyle

Question 16

Where does the ACL attach?

Answer 16

Anteriorly to the tibial plateau

Question 17

What is the role of the ACL?

Answer 17

Helps stabilise the joint

Question 18

Where is the posterior cruciate ligament located?

Answer 18

The anterior medial border of the medial femoral condyle

Where does the PCL attach?

Answer 19

Posteriorly to the tibial plateau

Question 20

Where does the fibular collateral ligament run from?

Answer 20

The lateral side of the lateral femoral condyle to the lateral aspect of the fibular head

Question 21

Where does the tibial collateral ligament run from?

Answer 21

The medial aspect of the medial femoral condyle to the medial aspect of the tibial shaft

Question 22

What does the medial collateral ligament do?

Answer 22

Resists a valgus force

Question 23

What is valgus force?

Answer 23

A force that tries to push the knee joint medially

Question 24

What does the lateral collateral ligament do?

Answer 24

Resists a varus force

Question 25

What is varus force?

Answer 25

A force that tires to push the knee laterally

Question 26

What do the popliteal ligaments do?

Answer 26

Provide stability to the posterior aspect of the tibiofemoral joint

Question 27

What are the 2 popliteal ligaments?

Answer 27

Oblique popliteal ligament (runnign diagonally across the posterior aspect of the knee)
Arcuate popliteal ligament (running down lateral aspect of the knee)

Question 28

Answer 28

A crescent shaped cartilage tissue

Question 29

Where are the menisci located?

Answer 29

Between the articular surfaces of the tibia and femur
