Will My Knee Replacement Last Forever?

If you are considering a knee replacement, you may be wondering how long it will last. The answer to that question is, unfortunately, "not forever." Knee replacements are made of metal and plastic, which over time, begin to wear. While they are designed to last many years, they will eventually need to be replaced.

What is a Knee Replacement and Why Might You Need One

A knee replacement is a surgery that replaces the worn-out surfaces of your knee joint with new, man-made surfaces. It's also called ‘knee arthroplasty.’

You might need a knee replacement if you have severe arthritis or another injury that has damaged your knee joint.

How Long Do Knee Replacements Last?

The average lifespan of a knee replacement is about 15 to 20 years. However, the exact amount of time that your replacement will last depends on a number of factors, including your health at the time of surgery, the type of implant you receive, and your level of activity following the surgery.

In general, those who are healthy and active prior to surgery tend to have longer-lasting replacements.

Factors That Impact How Long a Knee Replacement Lasts

There are a number of factors that can impact how long a knee replacement will last. For instance, patients who are overweight may put additional stress on their joints, which can lead to premature wear and tear. Likewise, patients who lead an active lifestyle may also put their joints at risk. In addition, the health of the bones, muscles, and ligaments surrounding the joint can also affect its longevity.

For example, patients with strong muscles and ligaments may be less likely to experience instability and dislocation, which can damage the joint.

Ultimately, the best way to ensure a long-lasting joint replacement is to maintain a healthy weight, lead a healthy lifestyle, and have strong surrounding tissues.

How to Prepare for Surgery

If you're getting ready for surgery, there are a few things you can do to make sure everything goes smoothly.

First, it's important to get your home ready. This means arranging for someone to stay with you or check on you several times a day during the first week or two after surgery.

You should also make sure you have everything you need within reach, including any medicines, ice packs, and pillows. This will help you avoid any unnecessary stress or movement during your recovery.

Second, it's important to follow your surgeon's instructions regarding diet and activity. This will help your body heal properly and reduce the risk of complications.

Finally, it's important to be as relaxed as possible on the day of surgery. This will help the procedure go more smoothly and minimize any discomfort.

Recovery After Surgery

Knee replacement surgery is a major surgery with a long recovery process. However, it is an outpatient surgery, which means you can go home the same day.

You will need someone to drive you home, as you will be unable to drive yourself.

Full recovery from knee replacement surgery takes about three to six months.

During that time you'll have physical therapy to help rebuild the strength and flexibility in your new knee joint.

Physical therapy will be essential in your full recovery.

It is important to follow your therapist's orders and do your exercises at home so that you can regain full use of your knee. With time and patience, you will be back to your old self in no time.
