Total Knee Replacement

Knee replacement surgery is among the most successful and proven interventions in modern medicine. A National Institutes of Health (NIH) study concluded that total knee replacement is extremely successful, resulting in “rapid and substantial improvement in the patient’s pain, functional status, and overall health-related quality of life in about 90% of patients.” More than 250,000 people a year undergo the procedure in the United States alone.

A total knee replacement is usually considered when the bone surfaces on both sides of the knee, as well as the underside of the kneecap (patella), are significantly damaged. In total knee replacement surgery, the surface of the thighbone (femur) is replaced with a contoured metal component designed to fit the curve of your bone. The surface of the shinbone (tibia) is typically replaced with a flat metal component and a smooth plastic component that serves as cartilage. The undersurface of the kneecap also may be replaced with an implant made of high tech plastic, or a combination of metal and plastic.
