Knee Replacement Knee replacement, or knee arthroplasty, is a surgical procedure to replace the
weight-bearing surfaces of the knee joint to relieve the pain and disability of
osteoarthritis. It may be performed for other knee diseases such as
rheumatoid arthritis and psoriatic arthritis. In patients with severe deformity
from advanced rheumatoid arthritis, trauma, or long standing osteoarthritis,
the surgery may be more complicated and carry higher risk. Osteoporosis
does not typically cause knee pain, deformity, or inflammation and is not a
reason to perform knee replacement.
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.
The operation involves substantial postoperative pain, and includes
vigorous physical rehabilitation. The recovery period may be 6 weeks or
longer and may involve the use of mobility aids.
Slide 3:
The Arthroscopic Knee Surgery is operated with the help of a small camera
inserted into the knee joint through a small incision and through the attached
video monitor doctor is able to see inside the knee. The surgeon pulls out
various tissues, a shaver to remove damaged or unwanted tissues such as torn
cartilage and a burr to remove bone.
Procedure
Knee replacement surgery is a procedure that is performed when the knee
joint has reached a point when painful symptoms can no longer be controlled
with non-operative treatments. In a knee replacement procedure, your
surgeon removes the damaged joint surface and replaces it with a metal and
plastic implant.
The procedure of knee replacement surgery involves removal of the damaged
bone of the knee joint and replacement with prosthesis or an artificial joint
made of metal alloys, high grade plastics and polymers.
Slide 4:
During the surgery, the knee is kept in bent position so that the surface of
the knee is fully exposed. An incision of 6-12 inches is made after which the
muscles, kneecap and connective tissues are moved aside to expose the
damaged joint surface. After smoothening the bone's rough surface, the
prosthesis is inserted.
Alternatives to Knee Replacement
Treatment should begin with the most basic options and progress to the
more involved, which may include surgery. Not all treatments are appropriate
for every patient.
Knee replacement is generally reserved for patients who have tried all of the
other treatments and are still left with significant pain during normal activities.
Patients who have occasional pain, are able to participate in athletic activities,
or have not tried non-operative treatments are probably not ready for a knee
replacement.
