How Long Does Knee Replacement Last?

For many individuals suffering from severe arthritis, knee replacement can be a life-changing procedure, allowing them to restore full function and resume a life free of chronic pain. More than 600,000 knee replacement procedures are performed in the United States every year. If you’re unable to find the relief you’re seeking from more conservative treatments such as cortisone injections or physical therapy, knee replacement may be the right solution to help you enjoy a pain-free life once again.

If you’re considering knee replacement, you may be wondering how long your new implant will last. The good news is that modern implants and knee replacement techniques deliver long-lasting results. However, knee implants aren’t meant to last forever. Over time, the materials used in knee implants may wear out and require replacement.

Most Knee Replacements Last 15 Years or Longer

In most instances, you can expect your knee replacement to last at least 10-15 years. Recent data published in the medical journal The Lancet found that:

Based on this data, roughly 90% of patients are having their knee replacements last at least 20 years. This figure is expected to rise over the next few years as well. Knee replacement technology continues to evolve at a rapid rate, and materials used today are more durable than ever. For example, the highly cross-linked polyethylene material used in many modern knee implants exhibits lower wear properties than the plastic and metal materials used in older implants. This should extend the lifespan of implants that use this more durable plastic.

In addition, there are new surgical techniques being used with knee replacement surgery that achieve more precise results and may potentially help your implant last longer. One technique which has significantly improved knee replacement results is the Mako Robotic-Arm Assisted Surgery System by Stryker. The 3D CT-based modeling software used with this technique gives surgeons a clearer picture of the surgical site and allows for a more customized surgical plan. This improved customization reduces risks, improves the precision of the procedure, and increases the likelihood of longer-lasting results.

Factors Impacting the Longevity of Your Knee Replacement

knee replacement patient While early failure of a knee implant is rare, it can occur in some situations. This generally happens as a result of an infection in the joint following surgery. Fortunately, you can minimize the chances of infection by effectively managing your risk factors before surgery.  This can be accomplished by:

When implants fail after long-term results, it is most commonly due to a loosening of the bond between the bone and the implant, which can occur from wear and tear over time. In some instances, long-term implant failure may also be caused by a component of the implant wearing down.

In general, the following factors will impact how long your knee replacement will last:
