What is knee replacement?
In knee replacement surgery, the bone surfaces and cartilage that have been damaged are removed and replaced with artificial surfaces, called implants, made of metal and plastic. The procedure is intended to give you restored mobility and reduce painful bone-on-bone contact.
Unicompartmental knee replacement
For some people with osteoarthritis, the joint damage is limited to only one portion of their knee. If you experience pain only on one side, or compartment, of your knee, your surgeon may prescribe what is called unicompartmental knee replacement. In this partial knee replacement surgery, only one side of the joint – the diseased portion – is replaced, leaving the healthy portion untouched.
Patella-femoral knee replacement
If you experience pain under the kneecap, your surgeon may recommend another type of partial knee replacement called patella-femoral knee replacement. This procedure replaces just the diseased portions of your knee, the femur and patella, while preserving the undamaged portion of your knee and your tibia.
When osteoarthritis affects more than one area of the knee, total knee replacement is often used as treatment. In total knee replacement surgery, the surface of the thighbone (femur) is replaced with a contoured metal piece. The surface of the shinbone (tibia) is typically replaced with a flat metal piece and a smooth plastic piece that serves as cartilage. The undersurface of the kneecap may also be replaced with an implant made of plastic or a combination of metal and plastic.
