How long will my new knee last, and can a second total knee replacement surgery be done?

All implants have a limited life expectancy depending on an individual’s age, weight, activity level and medical condition(s). We expect most knees to last more than 15-20 years. However, there is no guarantee that yours will last that long, and 5-10 percent will not last that long. A second replacement or a “revision” of the first joint replacement may be necessary. Although revision total knee replacement surgery can be done, it often doesn’t last as long as the first and carries a higher level risk of complication.
