biggest sesamoid bone in body?
patella
-apex
-base
of patella loc
apex =inferiorly
-superior
fibula funct
- provides site for musular attachment
* not really weight bearing

classify knee joint
synovial, hindge
*also element of
internal / external rotation
component of knee joint?
synovial capsule
extracapsular lig
intracapsular lig’s
patella serves as ..
a leaver for mechanical movement
weight leaver
classify
superior tibia fibular joint
synovial, plane
with all synovial joints they will have ..
lig supporting the capsule
patella tendon / lig attaches to..
tibial tuberosity
intracapsular structures *2
fem/tib joint
inside capsule
- menisci - med./lat. (fibrocartlige)
2.
menisci act as..
shock absorbers
medial menisci
larger or smaller?
larger (more c shaped)
menisci att to ?
medial menisci
- knee fibrous capsule
- tibial colateral lig
lat menisci
Q-angle
angle between thigh and
increase Q-angle
knock knees
decrease Q-angle
genu varum
—–outward pointing knees
femoral condyles sit on..
tibial plateaus
knee locking mechanism
is for ?
decr. mus output from the quad’s
the ability of the femar
to sit of the tibia
locking
and stay in that position without much mus contraction
*otherwise quad’s would have to be alway fully contracted and is tiring
poplateus mus (or tendon) is very important for
mn~ tai chi stance
unlocking of the knee
*going from fully locked to just under locked
mn= tai chi stance
> > > knee
extracapsular lig *5
- medial collateral (tibial collateral)
- lat. collateral (femoral collat.)
- patellar lig
- oblique popliteal lig
- arcuate popliteal lig
medial collat. lig runs..
from med epicond. femar
to
medial chondyle
