Knee Injuries Flashcards
wipe test
allows to see less obvious swelling of the knee. medial leg use palm to sweep up/ medialy and then down and laterally
ACL risk factor-Sex
1 in 29 female athletes and 1 in 50 male athletes
Female vs male atheltes RR=1.5
ACL risk factor- family history
1st degree relative- OR 2.53
What muscles could be involved in knee injury
hyperectesnion-hamstrings
hyperflexion-quates
valgus-pes anserine
also consider hip joint since some muscle that corss knee also cross hip
Injury prevention programs
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

Single leg jump
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
Anterior knee pain treatment strategies
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.
2 way pull on patella
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.
Knee extensor mechanism
lateral force, vertical force- drixn of pull (along valgus angle) follows femur- patella pulled laterally and up when quads contract.
