Knee Replacement Surgery
Whether it be that you blew out your knee playing
football, severe arthritis has deteriorated your cartilage,
or an unfortunate accident has injured your knee, we’ve all
heard stories of how crippling the pain and frustration can
be. The most common culprit is severe osteoarthritis, of
which are most noted in elderly patients, and the surgery
can provide an immense relief to those in need and aid you
through many years. Simply taking those nice, refreshing
walks can cause pain and the utmost discomfort. Even
sitting, or lying down, can cause knee pain and result in
major pain and frustration.
While medication can be useful, it usually just covers
the pain and can lead to an even worse state of your knee
because of the disillusionment of being pain free. If you
still experience pain while using walking supports with no
relief and have changed your activity levels, you may want
to consider total knee replacement surgery. By replacing the
damaged and worn surfaces of the knee, it can relieve pain,
correct leg deformity and help resume normal activities.
With surgical procedures rapidly advancing in favor of
the quick and easy pain relief, in 1968 the first knee
replacement was then performed. With it being one of the
most important orthopedic surgical advances of the twentieth
century, improvements in surgical materials and techniques
since then have greatly increased its effectiveness.
Approximately 581,000 knee replacements are performed each
year in the United States.
Arthroplasty, also known as the “go to” procedure for
procuring pain relief in severe arthritis patients, is
commonly referred as knee replacement surgery. This 2 hour
surgery can help relieve pain and restore function in
severely diseased knee joints. During knee replacement, our
orthopedic surgeon uses an artificial joint made of metal
alloys, polymers, and high-grade plastics that are put in
place of the damaged bone and cartilage from your thighbone,
shinbone, and kneecap.
Once you are under general anesthesia , spinal, or
epidural anesthesia, an eight- to twelve-inch cut is made in
the front of the knee. The injured part of the joint is
removed from the surface of the bones, and the surfaces are
then molded to hold a metal or plastic artificial joint. The
artificial joint is attached to the thigh bone, shin and
knee cap either with cement or a special substance. When fit
together, the fixed artificial parts form the joint, relying
on the nearby muscles and ligaments for support and
function.
Minimally invasive surgery (MIS) has revolutionized knee
replacement surgery as well as many fields of medicine. Its
key attribute is that it uses specialized procedures and
instrumentation to allow the surgeon to perform major
surgery without a sizeable incision.
MIS knee joint replacement necessitates a much slighter
incision, three to five inches, versus the standard method
and incision, which is typically eight to twelve inches. The
smaller, less invasive tactics result in less tissue trauma
by permitting the surgeon to work between the fibers of the
quadriceps muscles instead of requiring an incision through
the tendon. It can lead to less pain, decreased recovery
time and improved motion due to less scar tissue growth.
Currently this less invasive technique is accomplished by
only a minor fraction of orthopaedic surgeons in North
America. Because this kind of surgery remains relatively
new, research has been introduced to establish how the
immediate and long-term results will compare to traditional
surgery.
Knee replacement surgery is very successful, but the
success of the practice is partially due to the
rehabilitation phase that follows the surgery. For patients
anticipating a beneficial result from knee replacement
surgery, they must be an active rehab participant.
Rehabilitation after knee replacement commences immediately.
Patients will work with a physical therapist as soon as the
surgical procedure has been achieved. The importance in the
early phases of rehab is to maintain motion of the knee
replacement and to warrant that the patient can walk safely
and securely. The body reacts to surgery by creating scar
tissue, and patients may never recover normal motion if they
do not place emphasis on bending and straightening their
knee replacement.
