Answer 21

Strengthens inferolateral posterior joint capsule

Question 22

Anterolateral ligament

Answer 22

Stabiliser for rotation of the tibia?

Question 23

Anterior Cruciate Ligament

Answer 23

Limits:

anterior slide of tibia on femur

medial rotation

Question 24

Posterior Cruciate Ligament

Answer 24

Limits:

posterior slide of tibia on femur

medial rotation

Question 25

Medial & Lateral Meniscus

Answer 25

Shock absorption Increase congruence

Question 26

“Screw home” mechanism

Answer 26

* Contributes to tibiofemoral joint **stability** in extension * Close packed position

Question 27

Static: Menisci

Answer 27

* Withstand load bearing forces * Assist in movement of femoral condyles * Assist in stabilising translatory movements * Increase contact area at the tibiofemoral joint → reduces stress at the joint surfaces

Question 28

Iliotibial band

Answer 28

Affords some lateral joint stability particularly in flexion Assists ACL in preventing anterior slide of tibia on femur

Answer 34

* Limits plantarflexion * Prevents posterior slide of fibula and tibia on talus

Question 35

Posterior talofibular

Answer 35

* Limits dorsiflexion * Prevents anterior slide of tibia and fibula on talus

Question 36

Calcaneofibular

Answer 36
