How long do knee replacements last?

While knee replacements are designed to last a long time, they will not last forever.

The good news is that studies show that common types of knee replacements can last more than 20 years. How long your knee replacement will last depends on how active you are, how much you weigh, and your overall health. While some patients may have knee replacements that last several decades, other patients may require a repeat knee replacement just a handful of years after their surgery.
