Partial knee replacement is used when one side of the knee is damaged. It replaces only the damaged part of the knee.
Your doctor will make a cut in your knee. This cut is called an incision. It will leave a scar that usually fades with time.
You may be able to go home the same day. If you have partials on both knees at once, you may need to stay in the hospital for a day or more.
Most people go back to normal activities or work in 6 to 12 weeks. This depends on your health. It also depends on how well your knee does in your rehab program. This may take longer if you have both knees done at the same time.
