 Knee replacement surgery
If your knee is severely damaged by arthritis or injury, it may be hard for you to perform 
simple activities, such as walking or climbing stairs. You may even begin to feel pain while 
you are sitting or lying down.
If nonsurgical treatments like medications and using walking supports are no longer helpful, 
you may want to consider total knee replacement surgery. Joint replacement surgery is a 
safe and effective procedure to relieve pain, correct leg deformity, and help you resume 
normal activities.
Knee replacement, also known as knee arthroplasty, is a surgical procedure to replace the 
weight-bearing surfaces of the knee joint to relieve pain and disability. It is most commonly 
performed for osteoarthritis,[1]  and also 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.
Risks by knee replacement surgery :-
Knee replacement surgery, like any surgery, carries risks. They include:
• Infection
• Blood clots in the leg vein or lungs
• Heart attack
• Stroke
• Nerve damage
Total knee replacement :-
Patients with severe destruction of 
the knee joint associated with 
progressive pain and impaired 
function maybe candidates for total 
knee replacement.
• Osteoarthritis is the most 
common reason for knee 
replacement operation . 
• Physical therapy is an 
essential part of 
rehabilitation after total 
knee replacement.
• Patients with artificial joints 
are recommended to take 
antibiotics before, during, 
and after surgery. 
• Total knee replacements 
require surgery to implant 
artificial knee joints.
What is a total knee replacement ?
A total knee replacement is a surgical procedure whereby the diseased knee joint is 
replaced with artificial material. The knee is a hinge joint that provides motion at the point 
where the thigh meets the lower leg. The thighbone (or femur) abuts the large bone of the 
lower leg (tibia) at the knee joint.
During a total knee 
replacement, the end of the 
femur bone is removed and 
replaced with a metal shell. 
The end of the lower leg 
bone (tibia) is also removed 
and replaced with a 
channeled plastic piece with 
a metal stem. Depending on 
the condition of the 
kneecap portion of the knee 
joint, a plastic “button” may 
also be added under the 
kneecap surface. The 
artificial components of a 
total knee replacement are 
referred to as the 
prosthesis.
The posterior cruciate ligament is a tissue that normally stabilizes each side of the knee 
joint so that the lower leg cannot slide backward in relation to the thighbone. In total knee 
replacement surgery, this ligament is either retained, sacrificed, or substituted by a 
polyethylene post. Each of these various designs of total knee replacement has its own 
particular benefits and risks.
