1

What is the purpose of Anterior drawer test

instability of the ACL

2

How is the anterior drawer test performed

patient sat or laying down
knee 90 degree flexion
sit on foot of bent knee
hands placed either side of patella
tiba drawn forwards feeling for anterior translation

3

what makes a positive anterior drawer test?

increased anterior exertion of medial tibial condyle

4

What is the purpose of the Lachmans test

Instability of ACL

5

How is the Lachmans test performed

patient on back
rehab placed bent knee under clients knee
one hand fixed ontop of the patella
other hand under top of the calf
rehab drawers calf upwards

6

what makes a positive lachmans test

increased anterior exertion of tibia on femur
change in end feel indicates significant injury

7

what are the two tests used for ACL

Lachmans
Anterior drawer

8

Name the 8 tests for the knee

anterior drawer
lachmans
posterior drawer
posterior sag
McMurrays
Thessalys
Valgus stress test
Varus stress test

9

What is the purpose of the posterior drawer test

instability of PCL

10

How is the posterior drawer test performed

patient sat or laying down
knee 90 degree flexion
sit on foot of bent knee
hands placed either side of patella
tiba drawn backwards feeling for posterior translation

11

what makes a positive Posterior drawer test

increased posterior exertion of tibia on femur

12

Whats the purpose of the posterior sag

detect PCL instability

13

How is the posterior sag test performed

patient on back
knee 90degress flexion and hip 90 degree flexion looking for posterior translation

14

what makes a positive posterior sag test

posterior translation

15

What is the purpose of the McMurrays test

determine medial / lateral meniscal injury

16

how is the McMurrays test performed for medial meniscal injury

patient on back
one hand on top of patella holding it between thumb and finger applying varus force
other hand holding heel in heel of hand
slowly extend the knee while laterally rotating

17

How is the McMurrays test performed for lateral meniscal injury

patient on back
one hand on top of patella holding it between thumb and finger applying valgus force
other hand holding heel in heel of hand
slowly extend the knee while medially rotating

18

What determines a positive McMurrays test?

reproduction of symptoms
pain

19

what is the purpose of Thessalys test

detect meniscal injury

20

How is the thessalys test performed

standing on one leg
bend knee 20 degree flexion
rotate femur across body and back several times
external and internal rotation repeated

21

what makes a positive Thessalys test?

pain
apprehension
locking

22

what is the purpose of the Varus stress test?

pain / laxity LCL injury

23

How is the Varus stress test performed

leg lifted and rests between rehabbers hip and arm
one hand hold lateral side of leg below the knee
other hand applied pressure on the medial side forcing the ligament to open up

24

what makes a positive Varus stress test?

knee pain =lcl injury
normal end feel/ resistance to varus stress = intact ligament

25

What is the purpose of the vaalgus stress test?

Pain/ Laxity MCL

26

How is the Valgus stress test performed ?

leg lifted and rests between rehabbers hip and arm
one hand hold lateral side of leg below the knee
other hand applied pressure on the lateral side forcing the ligament to open up

27

what makes a positive valgus stress test?

knee pain = MCL injury
normal end feel/ resistance to valgus stress = intact ligament
