Partial Knee Replacement: Before Your Surgery
What is partial knee replacement?
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 4 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.
How do you prepare for surgery?
Surgery can be stressful. This information will help you understand what you can expect. And it will help you safely prepare for surgery.
Preparing for surgery
- You may need to shower or bathe with a special soap the night before and the morning of your surgery. It reduces the amount of bacteria on your skin that could cause an infection after surgery.
- Be sure you have someone to take you home. Anesthesia and pain medicine will make it unsafe for you to drive or get home on your own.
- Understand exactly what surgery is planned, along with the risks, benefits, and other options.
- Tell your doctor ALL the medicines and natural health products you take. Some may increase the risk of problems during your surgery. Your doctor will tell you if you should stop taking any of them before the surgery and how soon to do it.
- If you take aspirin or some other blood thinner, ask your doctor if you should stop taking it before your surgery. Make sure that you understand exactly what your doctor wants you to do. These medicines increase the risk of bleeding.
- Make sure your doctor and the hospital have a copy of your advance care plan. If you don't have one, you may want to prepare one. It lets others know your health care wishes. It's a good thing to have before any type of surgery or procedure.
What happens on the day of surgery?
Follow the instructions exactly about when to stop eating and drinking. If you don't, your surgery may be cancelled. If your doctor told you to take your medicines on the day of surgery, take them with only a sip of water.
Take a bath or shower before you come in for your surgery. Do not apply lotions, perfumes, deodorants, or nail polish.
Do not shave the surgical site yourself.
Take off all jewellery and piercings. And take out contact lenses, if you wear them.
At the hospital or surgery centre
Bring a picture ID.
The area for surgery is often marked to make sure there are no errors.
You will be kept comfortable and safe by your anesthesia provider. The anesthesia may make you sleep. Or it may just numb the area being worked on.
You may also get a shot of medicine into your spine. This will make your legs numb. You will not feel pain during the surgery.
You also will get antibiotics through an IV tube before surgery. This lowers the risk of an infection of the incision.
The surgery will take about 2 to 3 hours.
When should you call your doctor?
- You have questions or concerns.
- You don't understand how to prepare for your surgery.
- You become ill before the surgery (such as fever, flu, or a cold).
- You need to reschedule or have changed your mind about having the surgery.
