Total Joint Replacement
What is total joint replacement?
When an arthritic or damaged joint is removed and replaced
with an artificial joint called a prosthesis.
How is a total joint replacement
You will be given an anesthetic and the surgeon will replace
the damaged parts of the joint. For example, in an arthritic
knee the damaged ends of the joints are replaced with metallic & non
allergic & durable plastic surfaces that are
shaped to restore knee movement and function. In an arthritic
hip, the damaged ball is replaced by a metal ball attached
to a metal stem fitted into the femur, and a plastic socket
is implanted into the pelvis, replacing the damaged socket.
Although hip and knee replacements are the most common,
joint replacement can be performed on other joints, including
the ankle, foot, shoulder, elbow, and fingers.
The materials used in a total joint replacement are designed
to enable the joint to move just like your normal joint.
The prosthesis is generally composed of two parts. A metal
piece that fits closely into a matching sturdy plastic
piece. Several metals are used, including stainless steel,
alloys of cobalt and chrome, and titanium. The plastic
material is durable and wear resistant. A plastic bone
cement may be used to anchor the prosthesis into the bone.
Joint replacements also can be implanted without cement
when the prosthesis and the bone are designed to fit and
lock together directly.
TOTAL KNEE REPLACEMENT
Total knee replacement is an increasingly effective
and desirable approach to a range of problems affecting
the knee. It is one of the most consistently successful
therapeutic measures in all of medicine and surgery
today. Overall patient satisfaction with the relief
of pain and enhanced mobility is, in general, extremely
high. The procedure can provide many years of improved
mobility and reduced pain.
Though a total knee replacement is a major operation,
you should not feel alone in taking this path : each
year almost half a million all over the world benefit
from it. This information is aimed to make you understand
how a total knee replacement can improve the quality
of your life, we suggest that you speak to someone who
has had the successful surgery.
In the last decade remarkable improvements in technology
have transformed total knee replacement into an efficient
and widely performed procedure. Still, it is a significant
operation, and it demands that patients be given extraordinary
attention- before, during and after their hospital stay.

A Closer Look at Total Knee Replacement
To understand a total knee replacement, it helps to
understand the structure of the knee joint. The knee
is a complex joint that involves three bones: the femur,
the tibia, and the patella. When you bend or straighten
your knee, the end of the femur rolls against the end
of the tibia, and the patella glides in front of the
Research has steadily improved the materials available
for knee replacement. The durability of the prosthesis
can very from patient to patient because each patientís
body places slightly different stresses on a new knee.
Even so, you can expect to enjoy improved mobility,
relief of pain and the ability to walk for many years
TOTAL HIP REPLACEMENT
In a total hip replacement surgery,
the painful parts of the damaged hip are replaced
with artificial hip parts called prosthesis, a
device that substitutes or supplements a joint.
The prosthesis consists of three components: a
socket, ball, and stem. The outer shell of the
socket is usually made of metal and the inner
shell consists of plastic or the entire socket
may be plastic. When the metal ball is joined
with the socket, the new hip allows for smooth
nearly frictionless movement.
