26
Q

what soft tissue structure lies superficial to the vastus lateralis

A

IT band

27
Q

what is the VMO and what is it impt for

A

vastus medialis oblique

distal portion of the VM

important for patellar tracking (if weak, patella pulls laterally, if strong–pulls patella more medially)

28
Q

most common location for patellar injury

A

laterally

29
Q

where is popliteus found

A

very deep, posterior knee

30
Q

does popliteus touch the fibia

A

no

31
Q

what is the main function of the popliteus

A

unlocks the knee by rotation femur on fixed tibia

32
Q

to straighten knee/ lock, which way does the tibia rotate

A

quads straighten, bones do outward twist to lock

33
Q

to unlock knee, which way does the tibia rotate

A

popliteus unlocks by medially/inward twist

34
Q

where does superior gluteal nerve run to

A

TFL???

35
Q

where does the inferior gluteal nerve run to

A

gluteus maximus

36
Q

how many hamstring muscles are biarticulate

A

3 of 4

37
Q

which hamstring muscle is not biarticulate

A

biceps femoris

38
Q

what are the hamstring muscles

A

semitendinosus, semimembranosus, biceps femoris (long/short heads)

39
Q

what are the lateral 2 hamstring muscles and what are the medial 2

A

lateral: biceps femoris
medial: semitendinosus, semimembranosus (both semis go medially)

40
Q

what makes up the pes anserine

A

gracilis, semitendinosus, sartorius

41
Q

what is the order of the pes anserine, what are the nerves, and what’s the saying

A

SGT FOT

sartorius, gracilis, semitendinosus

femoral, obturator, tibial nerve

medial to lateral

42
Q

when does the femoral artery become the popliteus artery

A

after passing through the adductor hiatus in the adductor magnus

43
Q

where do clots happen in veins

A

deep vein (deep vein thrombosis)

44
Q

where are saphenous structures

A

medial leg

45
Q

what is a femoral hernia caused by

A

abdominal viscera protrudes through the femoral ring at the saphenous opening

46
Q

popliteal fossa contents

A

popliteal artery and vein, tibial nerve
AVN

47
Q

which nerve does lateral and which stays straight: tibial, common fibular

A

common fibular nerve goes lateral
tibial nerve stays straight

48
Q

whats the parent structure of common fibular nerve

A

sciatic nerve

49
Q

where are sural structures located

A

lateral lower leg

50
Q

genu varum and valgum laymans term

A

varum: bowleg (decreased Q angle)
valgum: knock knee (increased Q angle)

51
Q

what is the Q angle and do males or females have a bigger angle

A

difference between the line of gravity and where the femur runs/angle of the femur
female have a bigger Q angle bc hips are wider

52
Q

what movement does the LCL restrict

A
53
Q

what movement does the MCL/ tibia collateral ligament resist

A
54
Q

the oblique popliteal ligament is an extension of what tendon

A
55
Q

what movement does the ACL resist

A

prevents anterior displacement of tibia
hyperextension of knee joint

56
Q

what movement does the PCL resist

A

prevents anterior displacement of the femur on the tibia
prevents hyperflexion of knee

57
Q

ACL two bundles

A

AM and PL
anteromedial, posterolateral

58
Q

what part of the meniscus has blood

A

very outer part

59
Q

what meniscus is bigger

A

medial

60
Q

which meniscus is circular, smaller, and more freely moving

A

lateral

61
Q

which meniscus is c-shaped, wider posteriorly than anteriorly, and less mobile

A

medial

62
Q

which meniscus is more likely to be injured

A

medial

63
Q

what three structures are injured with an unhappy triad

A

MCL, ACL, and medial menisc
