What Is Knee Replacement Surgery?
An implant is then placed on the knee to create a new joint surface.
This implant functions similarly to a normal knee.

Total knee replacement surgery takes one to two hours and is performed by anorthopedic surgeonin a hospital.
Less often, it is performed in an outpatient surgical center.
Thetraditional techniqueinvolves making an 8- to 12-inch incision in the knee to expose the joint.
Once this is done, damaged tissues are removed and the knee implant is placed.
Computer-Assisted Total Knee Replacement
Some surgeons utilize a sophisticated computer imaging system when performing total knee replacements.
Talk with your surgeon if you are interested in this investigational technology.
Your implant will be selected during a pre-operative visit with your surgeon.
There are also different ways in which the implant is placed during the surgery.
Traditionally, the implant is fixed into the bone with cement.
Now, though, a novel cement-less technique may be used.
With the normal, smooth joint surface compromised, pain and disability can occur.
Rarely, children with juvenile idiopathic arthritis may undergo knee replacement surgery.
Start by removing fall hazards like throw rugs and loose electrical cords.
A nurse will then record your vital signs and place a peripheral IV in your hand or arm.
Your surgeon will want to ensure that your knee is maintaining good strength, stability, and mobility.
Will I Ever Need Revision Surgery?
Younger patients are more likely to experience implant loosening because they live longer and tend to be more active.
Do not hesitate to ask questions, voice your concerns, and seek out second opinions.
