Q

What prevents lateral dislocation of the patella?

A

Active: medial fibres of vastus medialis - keeps patella central
Passive: lateral ridge of patellar groove is higher than medial ridge - greater mechanical resistance to movement

27
Q

What is compromised if the neck of the femur is broken?

A

The blood supply to the head of the femur –> necrosis

28
Q

What prevents the hip joint from dislocating?

A

Fibrocartilaginous labrum captures the head of the femur

29
Q

What does the anterior cruciate ligament do?

A

Resists anterior translation of the tibia

30
Q

What does the posterior cruciate ligament do?

A

Resists posterior translation of the tibia

31
Q

What does the medial collateral ligament do?

Resists valgus force on the knee

32
Q

What does the lateral collateral ligament do?

A

Resists varus force on the knee

33
Q

At what degree of flexion of the knee is the ACL completely taut?
