Osteoarthritis affects more than 21
million individuals in the United
States. Degenerative joint disease
or osteoarthritis is one of the
oldest and most common forms of
arthritis. The disease causes the
normal smooth cartilage of the joint
to breakdown, causing pain and
discomfort. This arthritis process
results in bone against bone
friction and pain associated with
swelling, discomfort, loss of
movement and loss of mobility.
Osteoarthritis usually affects the
weight bearing sections of the knee,
which include the junction of the
lower leg bone (the tibia) with the
upper leg bone (the femur) and
beneath the kneecap (the patella.)
Disease may affect one section of
the knee (medial or inside) leaving
the other two sections relatively
healthy (outside or lateral and
kneecap), or it may affect two or
three of the sections of the knee.
Symptoms include joint pain and
often pain or discomfort at night
with some eventual loss of motion.
There are several options for
treatment of arthritis and as you
know, several promises and cures and
remedies have been explored
throughout the years.
Unfortunately, these palliative
treatments can help assist with some
pain, swelling and keep people
going, but ultimately when the pain
and arthritis get so severe, surgery
is needed.
Conservative
measures include icing, exercising,
range of motion, physical therapy,
and weight management to relieve
stress on the weight bearing joints,
as well as anti-inflammatory
medication (Motrin, Naprosyn,
Celebrex, or Vioxx), as well as
cortisone injections or Synvisc
injections. Ultimately if the
arthritis progresses to the point
where it causes pain or limitation
of motion and restriction of your
normal lifestyle, then surgical
treatment is needed. Surgical
treatment for knee replacement has
normally been a complete total knee
replacement, replacing all three of
the surfaces of the knee using metal
and plastic materials to resurface
the ends of the bone. Our newer,
minimally invasive solution (MIS)
incision is designed to allow
shorter hospital stays minimal blood
loss and quicker rehabilitation
secondary to the smaller incision.
Based on the examination with your
surgeon and after obtaining a x-ray,
it will be decided whether or not
you are a candidate for knee
replacement. Partial knee
replacement is a more conservative
alternative if indeed your arthritis
is limited to one compartment of the
knee joint. If indeed you are a
candidate for the procedure,
typically the MIS procedure is a
treatment option for approximately
10 to 20% of patients who are
suffering from knee arthritis.
Using the new specialized
instrumentation, we are able to
perform a minimally invasive
procedure through a 3-inch incision
as opposed to an 8 or 12-inch
incision required for traditional
knee replacement surgery. I only
remove the diseased portion of the
knee and cement in implants of the
prosthesis, while leaving the
healthy portions of the knee
untouched. This procedure usually
requires half the rehabilitation
time or hospital stay, minimal blood
loss and quicker rehabilitation.
We also feel that the patients will
experience quicker return of normal
range of motion and recovery after a
successful unicompartmental knee
replacement is performed. Partial
knee replacements are designed to
last approximately ten years.
Often younger people are candidates
for this procedure, based on the
fact that they are too young to
receive a total knee replacement.
This is a very excellent procedure
to be able to, what we call, buy
time and allow for a functioning
lifestyle until traditional knee
replacement can be utilized.
Partial knee replacements are used
for people who have osteoarthritis
limited to one compartment and/or
people who develop osteonecrosis,
which is a loss of bone cartilage
secondary to a problem with the
blood supply to the bone, but is not
utilized for patients who are
suffering from rheumatoid arthritis.
In summary, the results of this
procedure are very successful and do
allow quick rehabilitation and
improvement with a good long-term
pain relief, accomplishing a 95 to
98% pain relief satisfaction score.
Again, the limited knee surgery
hurts less, allows less time in the
hospital, and allows a more normal
range of motion and functioning
knee. If you have any further
