43
Q

A

Little bean

44
Q

Where is the fabella located?

A

tendon of the lateral head of the gastrocnemius muscle

45
Q

What is the correct name for the Patella tendon?

A

Ligamentum patellae

46
Q

What is another name for the surface that the patella glides upon?

A

Trochlear groove

47
Q

What structure covers the ends of bones within a synovial joint?

A

Hyaline cartilage

48
Q

The popliteus muscle is responsible for what action?

A

Unlocking the knee

49
Q

Which adductor muscle has an attachment to the adductor tubercle?

A

Adductor magnus

50
Q

What structure attaches to the Gerdy’s tubercle?

A

IT Band

51
Q

What are the TWO main joint actions for the gastrocnemius muscle?

A

Knee flexion

Plantarflexion

52
Q

Describe the screw home mechanism of the knee

A

Tibia rotates externally and the femur rotates externally to enter the closed packed position.

During the last 30 degrees of knee extension, the tibia (open chain) or femur (closed chain) must externally or internally rotate, respectively, about 10 degrees.
This slight rotation is due to inequality of the articular surface of femur condyles.
Rotation must occur to achieve full extension and then flexion from full extension

53
Q

What is the difference between the medial and lateral condylar surfaces of the femur?

A

The medial surface of the femur is larger
The lateral condyle of the femur is more anterior, to prevent lateral displacement of the patella

The lateral meniscis is larger in comparison to the medial

54
Q

Which nerve when injured causes drop foot

A

Deep peroneal nerve

55
Q

Which nerves supply the anterior knee?

A

Femoral and obturator

56
Q

Nerve to the lateral compartment of the knee

A

Superficial peroneal

57
Q

Nerve to the posterior compartment of the knee

A

Tibial

58
Q

What are the lymph nodes of the knee called?

A

Popliteal

59
Q

What are varicose veins and how do they form?

A

The valves of the veins become lax and weakened, allowing venous blood to back flow. The blood pools and collects causing the veins to adopt a warped, bulging appearance .

60
Q

What is dvt?
