I’m Josh medical correspondent today
we’ll be talking about the anatomy of
and common injuries to the knee the
needs a joint containing three bones the
first being the femur for the thigh bone
patella which is the kneecap and the
tibia which is a larger bone in the shin
at the end of each of these bones the
tissue called cartilage which allows for
smooth movement within the joint as well
as the desorption of shock due to
everyday movement the movement of the
knee is governed by two muscles in both
containing the thigh the first being the
quadricep which is the front of the
thigh which functions to extend or
straighten the leg and the hamstring
which is at the back of the thigh and
functions to bend the knee or contract
the leg in addition to the muscles
cartilage and bones in the knee there’s
a series of tendons and ligaments
ligaments being the ACL MCL PCL and lco
the ACL in the MCL are very common sites
of injury is we saw in the 2006
Superbowl playoffs Carson Palmer
injuring both of those with one hit the
function of the ACL is to sort of
stabilize rotation within the need to
prevent the knee from twisting too much
one way or the other however sometimes
in sports you’ll have a foot planted in
your body will twist one way or the
other such as in basketball when your
foots plants if you’re pivoting and what
will happen is the ACL will stretch upon
this twisting motion and depending on
the degree of the stretch it will either
be pulled or torn the same case is true
with the MCL however rather than
providing rotational support it provides
a linear support to the knee and what
happens when you playing a contact sport
like football or hockey if you get a
large impact to the outside of the knee
what will happen is the msci will
stretch and the same case depending on
the degree of the stretch you’ll either
pull or tear the MCN so depending on the
severity of the injury the
rehabilitation program can take anywhere
from two weeks to six months or more of
injury involve surgery but in any case
the rehabilitation program involves
strengthening exercises which allow the
muscles in the ligaments to regain
strength that they continue offering
support to the knee
with patience and adherence to a strict
training regimen outlined by a doctor or
physical therapist the individual the
injured knee can safely know that
they’re neat will regain strength and
they’ll be able to go back to the active
lifestyle that they had before with
little consequence due to the previous
knee injury
