Q

why is lachmans preferred over anterior drawer for ACT testing

A

25
what does a positive valgus indicate
MCL damage | perform apleys distraction
26
what test would you run to verify a valgus stress test
Apleys distraction
27
the best way to check a tibia AM for fluid motion
rotation | tight medial ligaments
28
is it normal to have a little bit of movement during valgus stress
yes
29
what other ligaments might be torn if the MCL is torn
medial meniscus, ACL
30
with valgus stress, excess motion indicates
MCL tear pain gets worse= partial tear pain stays the same= complete tear
31
should you compare valgus to varus stress on the same knee
no, compare right and left knees
32
what is the direction of pull for patella grind
S-I
33
what is the positive for patella femoral grinding test
pain or crepitius
34
what does a positive patella femoral grinding test indicate
chondromalacia patella
35
what is a positive patella femoral grinding most likely indicative of in an adult
DJD
36
which direction is pressure applied for patellar apprehension test
M-L, L-M
37
positive for a patella apprehension test
look of apprehension
38
most common direction for a patellar dislocation
superior and lateral
39
patella traction
flexed knee, hx causing pain
40
what are the findings to indicate the need for patellar traction
dislocation, unable to extend knee, patella is out of place
41
name 4 post checks for patellar traction
visualization, light palpation, active ROM, xray
42
what procedures would you not use for post-checking patellar traction
fluid motion, patellar apprehension, patella femoral grinding test
43
is the tibial tuberosity medial or lateral compared to inferior tip of the patella
slightly lateral
44
bounce holme test
knee doesn't bounce= joint mouse | swelling, guarding muscles, torn meniscus, scar tissue
45
what test would you run if you suspected a false positive with an anterior drawer sign of the knee
sag sign-> PCL
46
varus stress test
excess motion indicates a LCL tear pain gets worse= partial tear pain stays the same= complete tear
47
test to run to verify a positive varus stress test
Apley's distraction on LCL
48
knee traction can be used for what subluxations and pathologies
P tibia, AM tibia, AL tibia, OA, RA, other arthridities, fixation of the knee, knee swelling
49
CP for knee traction prone
thumb web
50
for a big-kneed pt and a doc with small hands, how might you modify knee traction prone
use a padded object as a fulcrum
51
which knee traction is the move of choice
prone
52
what is the best way to post check knee traction prone
keep pt in position and try various fluid motion checks within the knee
53
best post check for knee traction
fluid motion that wasn't there on the pre-check
54
knee traction is probably most effective for what subluxation
P tibia
55
what is the move of choice when there's limited flexion of the knee
knee traction, limited flexion
56
indications for lateral fibula
pain over fibular head, swelling over joint, pain on ankle ROM, loss of fluid motion
57
what is the pt placement for fibula lateral
supine, knee in full extension
58
what is the CP for fibula lateral
8 or 11
59
LOD for fibula lateral
L-M
60
MC missed on fibula lateral during a practical
not having straight L-M LOD or having knee flexed
61
what is the best post-check for fibula lateral
fluid motion
62
what protects the knee joint during the fibula lateral thrust
knee in full extension, SH across the knee joint
63
what is the first thing to do for tibia P
have pt prone and turn their head
64
what ortho test checks for tibia fluid motion
anterior drawer sign
65
what is pt placement for tibia P
prone, knee flexed less than 90 degress
66
LOC for tibia P
PA
67
where is the pain point for tibia posterior
pain in the back of the knee
68
what are some pathologies that might cause pain in the back of the knee
tibia P, baker's cyst, arthritis, aneurysm
69
what is the move of choice for tibia P
prone traction
70
what is done for pt protection for tibia P
have pt turn head before traction
71
describe the contact on the posterior tibia
hand over hand- do not interlock fingers
72
what would be a contraindication to tibia P thrusting
varicosities, thrombus, bakers cyst
73
why does a varicosity occur
incompetent valves
74
what can be done for varicosities
walk, support stockings, elevation
75
MC group to have varicosities
pregnant women
76
second MC group to have varicosities
middle-aged and older men
77
order of procedures for knee traction, limited flexion
flex to pt tolerance, traction, release, repeat
78
how many times do you flex, traction and release
repeat until no more flexion can be gained on that visit
79
would you expect more, less or same motion 24 hours after knee traction limited flexion
about 15% more movement once they begin using it after traction
80
why don't we traction, flex, and then release
it may entrap a joint mouse
81
best post check for knee traction limited flexion
increased ROM
82
what is the move of choice for any knee involvement
knee traction prone | you can palpate the joint at the same time
83
with the leg in full extension for AM tibia, where should the femur be
on the table, for stabilization
84
procedure after setting up on an AM tibia
traction, flex, thrust
85
what are some findings with an AM tibia
pain over joint space, toe-out, loss of valgus stress
86
what are your stabilizations for tibia AM
femur against table, SH, tib-fib between knees
87
what is the LOD for tibia AL
AP
88
what is the best post check for tibia AL
fluid motion | varus stress
