Knee injuries

Question 1

Wipe test

Answer 1

allows to see less obvious swelling of the knee. medial leg use palm to sweep up/ medialy and then down and laterally

Question 2

Risk factor for ACL - Sex

Answer 2

1 in 29 female athletes and 1 in 50 male athletes
Female vs male atheltes RR=1.5

Question 3

Risk factor for ACL - Family history

Answer 3

1st degree relative- OR 2.53

Question 4

Muscles involved in knee injuries

Answer 4

hyperectesnion-hamstrings
hyperflexion-quates
valgus-pes anserine
also consider hip joint since some muscle that corss knee also cross hip

Question 5

Prevention programs

Answer 5

to improve neuromuscular control for high risk sports- activate musculature/react faster.
P-plyometrics
F-Feedback of landing technique
A-Agility
B-Balance
S-Strength

Question 6

ACL injury prevention IRR

Answer 6

0.47

Question 7

Knee injury IRR injury prevention program

Answer 7

0.73

Question 8

injury prevention- female soccer, lower extremity injury IRR

Answer 8

0.73

Question 9

Single leg jump

Answer 9

control/limit: valgus knee position and hip internal rotation
address asymmetry in limb mechanics
increase knee flexion to absorb impact throguh knee
improve trunk control

Question 10

Anterior pain treatment

Answer 10

training of muscles- hip abductors help control valgus, hip internal rotation (limit int rot), quads (control range and load)
Some athletes food targeted exercise-targeted intrinsic muscles to increase stability and orthotics (stabilize while work on it) especially helpful for excessive pronators.

Question 11

Patella 2 way pull

Answer 11

deeper flexion- more compression of joint from quad-stronger more compression force (pushing patella against femur)
factors: higher body mass- more force- higher compression amount of knee flexion, alignment, muscle fatigue, form.

Question 12

Knee extensor mechanism

Answer 12

lateral force, vertical force- drixn of pull (along valgus angle) follows femur- patella pulled laterally and up when quads contract.
