A

Varus

17
Q

When the knee is fixed and the distal end of the tibia has deviated laterally.

A

Valgus Deviation (aka. Knock-Knee)

18
Q

When the knee is fixed and the distal end of the tibia has deviated medially.

A

Varus Deviation (aka. Bow-Leg)

19
Q

What are the 4 types of ligaments in the knee?

A

1) Collaterals
2) Cruciates
3) Coronary
4) Transverse

20
Q

What are the 2 collateral ligaments of the knee?

A

1) Lateral Collateral Ligament
2) Medial Collateral Ligament

21
Q

A pencil-like ligament of the knee that attaches to the lateral epicondyle of the femur and the fibular head.

A

Lateral Collateral Ligament (aka. Fibular Collateral Ligament)

22
Q

What does the LCL of the knee restrict?

A

Varus Deviation

23
Q

A ligament of the knee that attaches to the medial epicondyle of the femur and the medial condyle of the tibia. It is a flat thickening of the joint capsule and the deep fibres of the ligament are attached to the medial meniscus.

A

Medial Collateral Ligament (aka. Tibial Collateral Ligament)

24
Q

What does the MCL of the knee restrict?

A

Valgus Deviation

25
Q

What are the 2 cruciate ligaments of the knee?

A

1) Anterior Cruciate Ligament
2) Posterior Cruciate Ligament

26
Q

A ligament of the knee that attaches to the anterior intercondylar area of the tibia and the posteromedial side of the lateral femoral condyle. It is slack when the knee is flexed and taut when the knee is in full extension.

A

Anterior Cruciate Ligament

27
Q

What does the ACL of the knee restrict?

A

1) Anterior Translation of the Tibia on the Femur
2) Posterior Translation of the Femur on the Tibia
3) Knee Extension

28
Q

A ligament of the knee that attaches to the posterior intercondylar area of the tibia and the anterolateral side of the medial femoral condyle. It is slack when the knee is extended and taut when the knee is in full flexion.

A

Posterior Cruciate Ligament

29
Q

What does the PCL of the knee restrict?

A

1) Posterior Translation of the Tibia on the Femur
2) Anterior Translation of the Femur on the Tibia
3) Knee Flexion

30
Q

Ligaments of the knee that attach the medial and lateral menisci to their respective tibial plateaus.

A

Medial & Lateral Coronary Ligaments

31
Q

C-shaped plates of fibrocartilage attached to the articular surfaces of the tibia and the centre is thinner than the outer edges. They are slightly mobile and help in spreading of synovial fluid during knee movement.

A

Menisci of the Knee

32
Q

What do menisci of the knee function as?

A

1) Shock Absorbers
2) Deepen the Articulation to Provide Stability

33
Q

The medial meniscus is attached to the ______ __________ ligament.

A

Medial Collateral

34
Q

A ligament of the knee that connects the medial and lateral menisci anteriorly.

A

Transverse Ligament
