Knee Replacement

Knee replacement can often help alleviate pain and improve mobility in people who suffer from severe knee arthritis or previous knee injuries. The procedure effectively restores the function of your knee by resurfacing and replacing damaged joint parts with artificial joint parts.

Knee replacement surgery is often recommended after nonsurgical treatments have failed to relieve your symptoms. After a full assessment and discussing your options, your doctor will determine whether you are a good candidate for the procedure.

What to Expect: Knee Replacement Surgery

Most knee replacements are completed in about two hours. You can expect the following on the day of your surgery:

• An anesthesiologist will administer either general anesthesia (puts you to sleep during the surgery) or regional anesthesia (you will not be able to feel anything from the waist down) before the procedure begins. In addition, you will be given intravenous medication so that you’ll be asleep during surgery
• Your surgeon will make a six- to 10-inch incision and carefully move your kneecap to access the damaged or infected joint.
• The surgeon will then remove the damaged joint parts and replace them with the knee prosthesis.
• Once the knee implant in place, your surgeon will put your kneecap back in place, close the incision, and cover the wound with a protective surgical dressing.

Most patients can be discharged on the day of their surgery. Whereas others will need to stay one night in the hospital. Your care team will take measures to prevent infection, swelling, and blood clots. You will also will receive medication to manage your pain levels.

Upon your return home, you will be given exercises to help rebuild your strength and mobility. A physical therapist will show you how the exercises should be performed before you’re discharged from the hospital. It’s important to follow your physician’s instructions to ensure you make a full recovery.

You will need to use an assistive device, such as a walker or cane for a few weeks following surgery. It’s recommended that you find someone to help you with daily tasks while you recover. Most people are able to return to their normal activities within three to six weeks.

Your knee replacement care team may include specialists from these services:

• Orthopedics
• Home Care
• Physical Therapy & Rehab

As with any surgical procedure, there are risks associated with knee replacement surgery. Your doctor will discuss these risks and benefits with you before scheduling the procedure.
