Knee Surgery

Total or unilateral knee replacement

If your osteoarthritis is affecting your quality of life, your surgeon may recommend surgery.

Total knee replacement surgery In total knee replacement surgery, the surgeon reshapes the damaged bones to fit the shape of the metal prosthesis.

The thigh bone (femur) and the shin bone (tibia) are covered with two metal shells separated by a plastic liner.

If the kneecap (patella) is damaged, it might be lined with a plastic disc. 

Most people who have their knees replaced enjoy improved mobility and decreased pain for up to 15 to 20 years.

Partial knee replacement surgery A partial knee replacement surgery is done when the cartilage is damaged on only one side of the knee. The damaged part of the joint is removed and replaced with two metal shells separated by a plastic liner.

Often people who have a partial knee replacement surgery have a shorter recovery time compared to a total knee replacement.

Knee precautions after knee replacement surgeryKeep your knee moving after surgery; do NOT avoid exercising.  Knee bending exercises are very important for returning to normal activities.  When resting, ensure that your knee is straight.  Do not use a pillow under your knee.  

These activity restrictions will help your joint to heal and reduce stiffness in the new joint.
