- lateral
- patellofemoral

10

medial compartment of the knee

- medial condyle
- medial meniscus
- medial tibial plateau

11

lateral compartment of the knee

- lateral condyle

12

What does a strong quad prevent?

hyperextension

13

What is the purpose of q angle?

- a way to look at alignment of the lower extremities

3

17

What are the 3 compartments of the lower leg?

- anterior
- lateral

18

compartment syndrome

- fluid builds up in compartment or open space between compartment
- puts pressure on vascular tissue

19

What forms the superior portion of the ankle?

- distal end of the tib-fib joint
- MORTIS

20

What is a primary function of the fibula during WB?

dissipates force to the tibia via the interosseous membrane by flexing

21

What is the type of joint is the distal tib-fib joint?

syndesmosis

22

What is injury to the distal tib-fib syndesmosis?

high ankle sprain

23

What is the ankle joint called?

talocrural joint

24

Which is closer to the ground: tibia or fibula?

fibula

27

Which aspect of the dome of the talus is wider?

anterior aspect is wider than posterior aspect

28

What happens to the head of the talus during dorsiflexion?

dome glides posterior into the mortise

29

What happens to the distal tibia and fibula during dorsiflexion?

- spread apart
- gapping of the syndesmosis

30

Where does dorsiflexion and plantarflexion occur?

talocrural joint
