Knee replacement is a surgical
procedure to rectify serious knee damage by removing damaged
cartilage and bone in the knee joint. Then, human made artificial
bones or joints are replaced. Knee replacement can relieve pain and
allow you to be more active. Knee replacement surgery can be
performed as a partial or a total knee replacement. In general, the
surgery consists of replacing the diseased or damaged joint surfaces
of the knee with metal and plastic components shaped to allow
continued motion of the knee. Knee replacement surgery is most
commonly performed in people with advanced osteroarthritis. It
should be considered when conservative treatments have been
exhausted. Total knee replacement is also an option to correct
significant knee joint or bone trauma in young patients.
Knee replacements are usually
performed on people suffering from painful arthritic conditions of
the knee severe enough to limit one's normal day to day activities.
Most people who have artificial knees are over age 55, but the
procedure is also offered to younger people with knee degeneration if
their quality of life is severely affected.
Types of Knee
replacement surgery
Traditionally, patients have undergone
total knee replacement for serious arthritis of the knee joint. But
now, the system changed, partial knee surgery or a uni -compartmental knee arthroplasty, is a surgery that may be
considered for treatment of osteoarthritis of the knee joint. The
advantage is that, here a small cut is made and recovery period is
tool fast, whereas total knee replacement, all cartilage is removed
from the knee joint through a big incision.
In a total or full knee replacement,
both sides of your knee joint are replaced. The procedure takes one
to three hours:
* The surgeon makes a cut down the
front of your knee to expose your kneecap. This is then moved to the
side so the surgeon can get to the knee joint behind it.
* The damaged ends of your thigh bone
and shin bone are carefully cut away. The ends are precisely measured
and shaped to fit the appropriately sized prosthetic replacement. A
dummy joint is positioned to test that the joint is working properly.
Adjustments are made, the bone ends are cleaned, and the final
prosthesis is fitted.
* The end of your femur is replaced by
a curved piece of metal, and the end of your tibia is replaced by a
flat metal plate. These are fixed using special bone 'cement', or are
treated to encourage your bone to fuse with the replacement parts. A
plastic spacer is placed between the pieces of metal. This acts like
cartilage, reducing friction as your joint moves.
You will usually be in hospital for 6
to 10 days. Patients who have had a half knee replacement usually have a shorter hospital stay. You may be given some specific
exercises to do. You may also be given advice on taking short walks
and carrying out normal household activities, such as walking up and
down stairs. These exercises will help restore your movement and
strengthen your new knee. Even after you have recovered, it is best
to avoid extreme movements or sports where there is a risk of
falling, such as skiing or riding a bicycle.
