Knee Flashcards
femur condyles
medial condyle is longer and larger
tibia plateaus
medial plateau bigger
Genu Valgum
knock knee
excessive inward angle
femoral to tibial angle is less than 165
genu varum
bow legged
excessive outward angle
femoral to tibial angle is more than 180
genu valgum knee pain
lateral compartment compressed
genu varum knee pain
medial compartment compressed
factors that lead to genu valgum
high BMI
lax of ligs
excessive LATERAL TRACKING
females more likely
clinical fixes for genu
bracing can be applied to offset unilateral compartmental OA
and a high tibial osteotomy HTO
genu recurvatum
knee goes into hyperextension
weak posterior capsule
Q angle
line of pull of quads
ASIS to patella
factors that oppose lateral pull of patella
VMO
patella alta - raised lateral groove
factors that lead to lateral pull of patella
tight IT band
Genu valgum
medial meniscus connects to
MCL ACL PCL semimembranosis
lateral meniscus connects to
ACL PCL popliteus
MOI for meniscus
axial rotation over a flexed knee
meniscus constantly stressed
posterior horn of meniscus during stance phase of gait
compression on meniscus
circumferential tension
meniscus helps with what in the joint
reduces stress
increases contact area
meniscus more stressed at
past 90 degrees of FL and in leg extension 20-0 of OKC
ACL resists
anterior translation of tibia
PCL resists
posterior translation of tibia
MCL resists
Valgus force
LCL resists
Varus force
IT band assists what knee lig
ACL
