Total Knee Replacement

What is Total Knee Replacement?

This is an operation with a success rate of over 90 per cent at 10 years. It can restore your mobility and greatly reduces pain, hence its popularity.

The operation involves replacing the joint surface at  both sides of the knee joint -  at the  end of your femur (thigh bone) and the joint surface at the tip of the tibia (shin bone). In some cases the patella or knee cap may also be replaced.

Experts say a new knee should last you between 15 and 20 years.

 

What Happens? Step-By-Step

  • The diseased end of your femur and tibia are removed and a made to measure artificial joint is inserted.
  • Then the end of the femur is replaced by a curve-shaped piece of metal and the end of the tibia by a metal plate.
  • Both are fixed in place with a special type of cement or textures to encourage the bone to grow onto the component.
  • A piece of plastic is inserted between the metal pieces to act as a substitute for cartilage, reducing wear and tear/ friction as you move your knee.
