Total Knee Replacement Specialist

Why is a total knee replacement performed?

The knee comprises three bones – the femur (thigh bone), the tibia (shin bone) and the patella (or kneecap). The ends of the tibia and femur are covered in a protective layer of cartilage which helps the joint move smoothly and without pain. Total knee replacement surgery is performed to replace a knee joint that has become diseased or damaged. The most common causes for total knee replacement are osteoarthritis and rheumatoid arthritis, both of which cause substantial damage to the joint surfaces, causing inflammation and pain as well as limited range of motion. During total knee replacement, the worn ends of the tibia and femur are replaced with synthetic components designed to help the joint function normally again.

What happens during the procedure?

During total knee replacement (TKR) surgery, an incision is made above the knee joint to enable the joint to be accessed. The ends of the tibia and femur are prepared for the implants and cleaned of debris. Typically, this involves removing the damaged cartilage as well as a small amount of bone. Once the bones are prepared, the implants are put in place. The patella may also be resurfaced, depending on whether it's damaged or resurfacing is necessary for the new joint to work properly. Next, a spacer is inserted between the implants to help the joint move smoothly. Once the placement of the implant is confirmed, the incision will be closed.

What can I expect during recovery?

Usually within a day of your surgery, you'll be out of bed and moving with the assistance of a walker or cane. Physical rehabilitation will also begin soon after surgery and will continue throughout your recovery. Most men and women recover from surgery within several months as long as they are willing to participate regularly in physical therapy activities.
