Knee ReplacementMore Than One Knee Replacement

According to the Center for Disease control fact sheet there were around 50,000,000 inpatient surgeries in 2014. That’s enough surgeries for around one in seven people in the United States. Out of the 50 million people who had to get surgery performed last year almost 720,000 total knee replacements were performed. The only issue more scary than the fact that 720,000 total knee replacements were performed, is the fact that a large percentage of those people are getting a knee replacement for a second or third time! Not only is a total knee replacement bad enough, the revision surgery, or the second time you receive surgery, is more likely to cause you health risks. Check out what is saying about knee replacements.

“Although today’s implants are designed to last many years, it’s possible that at some point in the future—typically 15 to 20 years or more—your prosthetic will break or wear out. If you are overweight or you engage in high impact activities such as running or court sports, the device may fail sooner. When a knee replacement no longer functions correctly, revision surgery is often required. During this procedure, a surgeon replaces the old device with a new one.”

What does this mean? If you’ve been active all of your life, overusing your knees, overweight, or have been in an accident causing a knee injury, there is a chance that you will be told you need a knee replacement at a relatively young age. It isn’t surprising to hear about a 45 year old receiving a total knee replacement. After all the average age to receive a total knee replacement is from 50-75. So if you are told to get a knee replacement when you’re 45 you can expect to need another knee replacement, or a revision surgery, when you’re 60-65. Since the average lifespan in the us is 78 you’ll most likely experiencing a total knee replacement at least twice in your life.

Second Knee Replacement Reasons

You’re probably wondering why you’ll need another knee replacement or a revision surgery, right? You’re most likely thinking that perhaps you need a second knee replacement because changes in your body, wear and tear on the artificial knee, or mechanical failure.


Infection is one of the main reasons why most people need to have their knee replacement, replaced again. According to

“An infection will usually present itself within days or weeks of surgery. However, infection can also occur many years after surgery. The complication rate for surgery due specifically to mechanical failure of the implant is 0.7 percent according to the Center of Medicare and Medicaid Services (CMS). However, CMS data also indicates that the average rate of revision surgery within 90 days is only 0.2 percent; within 18 months, the rate jumps to approximately 3.7 percent. “

What does this all mean? This means that immediately after surgery you have a low chance of getting an infection. However, 18 months later the odds of getting an infection jump up to almost 4%.

Long Term Replacement Reasons

Just like your normal knee joint, the artificial knee isn’t indestructible. In fact it seems as though the knee you were born with is much more durable. The reasons why people need to have a knee replacement for a second and third time vary. Some of the factors include the age of the patient, your weight, the condition of the artificial joint etc.

Just like your original knee joint if you don’t maintain your weight you’re in more risk of having to have the knee replacement, replaced. If you overuse your replacement knee you’ll be more at risk of having to get another knee replacement because of mechanical wear and tear. Just because you got a knee replacement doesn’t mean you are set for life. In fact the knee replacement causes many issues that wouldn’t have been introduced without the total knee replacement. A process called aseptic loosening is likely to occur. This is when the bond between the implant begins to break down. As the breaking down occurs the body attempts to digest the particles and it takes the surrounding bone with it. The body literally harms itself because of the knee replacement.

Non-Invasive Surgery

A total knee replacement is common, but it’s also a very serious surgery. If you are suggested to undergo surgery make sure you get a second opinion. There are other options out there that don’t require surgery, don’t have any chance of infection and are very effective.
