Knee Replacement- A Best Solution of
Arthoplasty Knee arthroplasty replaces a
damaged, worn, or diseased knee joint. The goal
is to eliminate pain and restore mobility. If
an injury damages the cartilage or is worn away
by arthritis, it can make the joint ache or
stiff. Generally, a new knee joint improves
mobility and reduces pain, although your new knee
will not be able to bend as much as a normal
knee joint. Depending on your knee joint
condition, they will replace part or all of your
knee joint. A total knee replacement is more
common. Artificial knee pieces can be made of
metal and/or plastic, and a knee replacement can
last up to 20 years.
WHAT ARE THE ALTERNATIVES? The Knee Replacement
Surgery is generally recommended only if
nonsurgical treatments, such as physical therapy
and exercise, taking medications, or using
physical support devices such as a cane, no
longer help to decrease pain. Alternative
surgical procedures include arthroscopy (if the
arthritis is not very severe) or osteotomy (in
which the leg bones are cut and put back). The
Knee Replacement Surgeon will explain best
options to you. PREPARING FOR A KNEE
REPLACEMENT The Best Doctors in India will
explain how to get ready for the operation. For
example, if you smoke, they will ask you to stop
smoking, which increases your risk of infection
in the chest and wound, which can delay your
recovery. You usually need to stay in the
hospital for best quality treatment in India
about five days, and the surgery is done under
general anesthesia. If you prefer, the surgery
can be performed under epidural or spinal
anesthesia. This type of anesthesia completely
numbs from the waist down, and you will remain
awake during the operation. If you are going to
have general anesthesia, you will be asked to
fast. This means that you should not eat or
drink normally for about six hours before general
anesthesia. However, it is important to follow
the instructions of your anesthetist. The nurse
can check your heart rate and blood pressure in
the hospital and do a urine test.

For you, the chirurgie will explain what will
happen before, during, and after the procedure
and any pain you may have. This is your
opportunity to understand what will happen, and
it may help prepare questions about the risks,
benefits, and other alternatives to the
procedure. This will help you stay informed to
give your consent if you are asked to sign a
consent form to perform the procedure. You may
be asked to wear compression stockings on your
unaffected leg to prevent blood clots from
forming in your veins (deep vein thrombosis,
DVT). You may need an injection of a
blood-thinning medicine called heparin in
addition to or instead of wearing compression
stockings. WHAT HAPPENS DURING A KNEE
REPLACEMENT? Generally, a knee replacement takes
about two hours. The surgeon will make a single
cut (10 to 30 cm long) in the front of your knee.
You will push the kneecap to the side to reach
the knee joint. The surgeon will remove the worn
or damaged surfaces from the end of the femur
and the top of the tibia. Typically, the
anterior cruciate ligament will be removed, and
the posterior cruciate ligament may be removed.
For support, the surgeon will not remove the
collateral ligaments. It will shape the femur
and tibia surfaces to fit the artificial knee
joint and then fit the new joint over both
bones. Sometimes the back of the kneecap is
replaced with a piece of plastic. This is known
as patella lining. After placing the new joint,
the surgeon will close the wound with stitches or
clips and cover it with a bandage. The surgeon
will place a tight bandage on your knee to help
minimize swelling.
