Total Knee Replacement

tkr1Total knee replacement surgery involves removing parts of the damaged knee and replacing them with artificial parts called prostheses. Damage is the result of arthritis and/or injury.

The knee replacement consists of three pieces:

Femoral component

Metal piece that caps the end of the femur and has a groove, which allows the kneecap to move up and down as the knee bends and straightens.

Tibial component

Flat piece of metal with a plastic (polyethylene) plate that covers the top of the tibia or the shin bone.

Patellar component

Dome-shaped piece of plastic that allows the kneecap to glide smoothly over the new knee.
