what are the findings to indicate the need for patellar traction

A

dislocation, unable to extend knee, patella is out of place

41
Q

name 4 post checks for patellar traction

A

visualization, light palpation, active ROM, xray

42
Q

what procedures would you not use for post-checking patellar traction

A

fluid motion, patellar apprehension, patella femoral grinding test

43

is the tibial tuberosity medial or lateral compared to inferior tip of the patella

A

slightly lateral

44
Q

bounce holme test

knee doesn’t bounce= joint mouse

swelling, guarding muscles, torn meniscus, scar tissue

45
Q

what test would you run if you suspected a false positive with an anterior drawer sign of the knee

A

sag sign-> PCL

46
Q

varus stress test

A

excess motion indicates a LCL tear
pain gets worse= partial tear
pain stays the same= complete tear

47
Q

test to run to verify a positive varus stress test

A

Apley’s distraction on LCL

48
Q

knee traction can be used for what subluxations and pathologies

A

P tibia, AM tibia, AL tibia, OA, RA, other arthridities, fixation of the knee, knee swelling

49
Q

CP for knee traction prone

A

thumb web

50
Q

for a big-kneed pt and a doc with small hands, how might you modify knee traction prone

A

use a padded object as a fulcrum

51
Q

which knee traction is the move of choice

A

prone

52
Q

what is the best way to post check knee traction prone

A

keep pt in position and try various fluid motion checks within the knee

53
Q

best post check for knee traction

A

fluid motion that wasn’t there on the pre-check

54
Q

knee traction is probably most effective for what subluxation

A

P tibia

55
Q

what is the move of choice when there’s limited flexion of the knee

A

knee traction, limited flexion

56
Q

indications for lateral fibula

A

pain over fibular head, swelling over joint, pain on ankle ROM, loss of fluid motion

57

supine, knee in full extension

58
Q

what is the CP for fibula lateral

A

8 or 11

59
Q

LOD for fibula lateral

A

L-M

60
Q

MC missed on fibula lateral during a practical

A

not having straight L-M LOD or having knee flexed

61
Q

what is the best post-check for fibula lateral

A

fluid motion

62
Q

what protects the knee joint during the fibula lateral thrust

A

knee in full extension, SH across the knee joint

63
Q

what is the first thing to do for tibia P

A

have pt prone and turn their head

64
Q

what ortho test checks for tibia fluid motion

A

anterior drawer sign

65

PA

67

pain in the back of the knee

68
Q

what are some pathologies that might cause pain in the back of the knee

what is done for pt protection for tibia P

A

have pt turn head before traction

71
Q

describe the contact on the posterior tibia

A

hand over hand- do not interlock fingers

72

Q

why does a varicosity occur

A

incompetent valves

74

walk, support stockings, elevation

75
Q

MC group to have varicosities

A

pregnant women

76
Q

second MC group to have varicosities

A

middle-aged and older men

77
Q

order of procedures for knee traction, limited flexion

A

flex to pt tolerance, traction, release, repeat

78
Q

how many times do you flex, traction and release

A

repeat until no more flexion can be gained on that visit

79
Q

would you expect more, less or same motion 24 hours after knee traction limited flexion

A

about 15% more movement once they begin using it after traction

80
Q

why don’t we traction, flex, and then release

A

it may entrap a joint mouse

81
Q

best post check for knee traction limited flexion

A

increased ROM

82
Q

what is the move of choice for any knee involvement

A

knee traction prone

you can palpate the joint at the same time

83
