Flashcards in 04 Knee Special Tests: Meniscus Deck (18):
1

clusters of s/s for meniscus tests?

- history of macrotrauma
- twisting MOI
- delayed effusion
- reproducible click/clunk
- pseudolocking
- joint line pain

2

How do older people commonly get a twisting MOI?

- can just go from kneeling to standing
- normal screw home mechanism of the tibia

3

delayed effusion time

over 12 hours

4

What else does the recurvatum test assess aside from the PCL?

anterior horns of the meniscus

5

What does Steinman's test assess?

posterior horns of the meniscus

6

How to do Steinman's test

- flex hip to 90˚
- slowly flex knee
- proximal hand palpates medial/lateral joint line
- distal hand at ankle
- 3 overpressures

7

What is McMurray's test?

- end position of Steinman's test
- take distal hand and put under heel
- internally and externally rotate tibia 3x

8

What is McMurray's test assessing?

posterior horns of meniscus

9

What is a positive Steinman's or McMurray's test?

- pain on joint line palpation
- 95% positive predictive value for meniscus tear

10

What does the dynamic McMurray's test assess?

entire meniscus
- posterior horns
- middle
- anterior horns

11

dynamic McMurray's test: part 1

- hand on heel, forearm on medial side of foot to ER tibia
- give valgus force on lateral femoral epicondyle, fingers to ceiling
- move knee from flexion to extension
- don't let hip go into IR

12

dynamic McMurray's test: part 2

- hand on heel, forearm on lateral side of foot to IR
- varus force to medial side of knee
- move from flexion to extension
- hand under posteromedial portion of knee to prevent bounce

13

What does the Apley's compression test assess?

posterior horns of meniscus

14

Apley's compression position

- prone
- flex knee to 90˚
- hands on heel
- give axial compressive loading while internally and externally rotating tibia

15

positive Apley's compression test

- replication of joint line pain
- snapping
- cracking
- clicking, clunking, pseudocatching, locking

16

What does the Apley's dynamic compression (DDV) assess?

entire meniscus

17

What do you need to remember before performing the Apley's dynamic compression (DDV)?

put a towel or pillow under the distal femur so patella isn't being crushed on the table

18

positioning for the Apley's dynamic compression (DDV)

- prone
- knee flexed to 90˚
- compress, externally rotate, and take knee to full extension 3x
- repeat with internal rotation
