What is a knee replacement?
In total knee replacement surgery, the parts of the bones that rub together are resurfaced with metal and plastic implants. Using special, precision instruments, your surgeon will typically remove the damaged surfaces of all three bones. The replacement surfaces will then be fixed into place.
The surface of the femur is replaced with a rounded metal component that comes very close to matching the curve of your natural bone. The surface of the tibia is replaced with a smooth plastic component. This flat metal component holds a smooth plastic piece made of ultra-high-molecular-weight polyethylene plastic that serves as the cartilage. The undersurface of the kneecap may also be replaced with an implant made of the same polyethylene plastic.
How do I prepare for knee replacement surgery?
If you and your surgeon decide that total knee replacement is right for you, a date will be scheduled for your surgery. Several things may be necessary to prepare for surgery. For example, your surgeon might ask you to have a physical examination by an M.D. physician or your regular doctor.
Because blood transfusions are likely to be needed during your surgery, you may want to donate one unit of your own blood or possibly two units if your surgeon feels it is needed. All preparations for surgery should be discussed with your surgeon.
How soon can I return to normal activities after surgery?
Within six weeks after surgery, most patients are able to walk without a cane. You will probably feel well enough to drive a car within seven to eight weeks after surgery.
In most cases, successful joint replacement surgery will relieve your pain and stiffness, and allow you to resume many of your normal daily activities. But even after you have fully recovered from your surgery, you will still have some restrictions. Normal daily activities do not include contact sports or activities that put excessive strain on your joints. Although your artificial joint can be replaced, a second implant is seldom as effective as the first.
How common is knee replacement surgery?
Knee replacement is a routine surgery performed on over 600,000 people worldwide each year. Over 90% of people who have had Total Knee Replacement experience an improvement in knee pain and function.
How old is the average patient?
In the U.S., the average joint replacement patient is around 65-70 years old, however patients of all ages have received knee implants.
How long will my artificial Knee joint last?
There are several factors on which longevity of Implants depend. Your Doctor will explain you in detail but approximately it will last for 18-22 years in 96% of patients
