Knee joint replacement is surgery to replace a knee joint with a man-made joint. The artificial joint is called a prosthesis.Description

Damaged cartilage and bone are removed from the knee joint. Man-made pieces are then placed in the knee.Knee joint replacement prosthesis

These pieces may be placed in the following places in the knee joint:

You will not feel any pain during the surgery. You will have one of these two types of anesthesia:

The surgery takes about 2 hours.

Most artificial knees have both metal and plastic parts. Some surgeons now use different materials, including metal on metal, ceramic on ceramic, or ceramic on plastic.

Most of the time, knee joint replacement is done in people age 60 and older. Younger people who have a knee joint replaced may put extra stress on the artificial knee and cause it to wear out early.

Before the Procedure

Always tell your doctor or nurse what drugs you are taking, including drugs, supplements, or herbs you bought without a prescription.

During the 2 weeks before your surgery:

On the day of your surgery:

After the Procedure

You will stay in the hospital for 3 to 4 days. During that time, you will recover from your anesthesia and from the surgery itself. You will be asked to start moving and walking as soon as the first day after surgery.

Full recovery will take 4 months to a year.

Some people need a short stay in a rehabilitation center after they leave the hospital and before they go home. At a rehab center, you will learn how to safely do your daily activities on your own.

Outlook (Prognosis)

The results of a total knee replacement are often excellent. The operation relieves pain for most people. Most people do not need help walking after they fully recover.

Most artificial knee joints last 10 to 15 years. Some last as long as 20 years before they loosen and need to be replaced again. Talk to your doctor if you have pain and symptoms from your artificial joint soon after the replacement.
