Total Knee Replacement

You're not alone if you're thinking about total knee replacement. More than 600,000 Americans undergo this surgery annually, usually due to arthritis that causes cartilage in the joint to deteriorate.

More than 90 percent of patients who have total knee replacement surgery enjoy a dramatic reduction of knee pain, according to the American Academy of Orthopedic Surgeons. If you're like most of the patients having this surgery, you'll also see a significant improvement in your ability to perform common daily activities.

During a total knee replacement your entire knee joint is removed and replaced with an artificial joint. The implant is designed to move just like a healthy human joint. Surgery involves the:

  • Lower end of the femur (thigh bone). The replacement part is usually made of metal.
  • Upper end of the tibia (shin bone). The replacement part is usually made from metal and a strong plastic.
  • Back side of the patella (kneecap). The replacement part is usually made from a high-grade plastic.

Revision Knee Replacement

After years of use or overuse, or if you're overweight, components in your knee implant can wear down and become detached from the bone to which they were once anchored. This could require a revision knee replacement.

During this procedure, the surgeon removes components of the original implant, bone cement and loose tissue without damaging surrounding bone surfaces. When the surgeon places the new implant, a thicker, more deeply implanted stem component may have additional reinforcements.
