POST SAG TEST

Question 14

MCL anatomy

Answer 14

medial tbis proximal
medial epicondyle femur

taut in ext and end of flexion

Question 15

MCL function

Answer 15

prevents valgus/ abduction
limit extension/ internal rotation
resist anterior tib translation

Question 16

MCL MOI

Answer 16

meniscus test

Answer 21

McMurrays
steinman displacement

Question 22

Ptella dislocation types

Answer 22

single- trauma
reccurent- regular
habitual- every knee movement
persistant- sublaxation

Question 23

patella MOI dislocation

Answer 23

traumatic powerful quad contraction
blow

ligament laxity

Question 24

patella fracture MOI

Answer 24

direct blow
forceful contraction

decrease inability to extend knee

Question 25

LCL anatomy

Answer 25

lateral epicondyle
head of fibula

resists varus/ adduction
limit external rotation

HYPEREXTENSION
direct medial blow
rotatory dislocation

Question 27

test LCL
