How long does a knee replacement last?
As successful as most of these procedures are, over the years the artificial joint can become loose or wear out, requiring a revision (repeat) surgery. How long it will last depends not only on a person’s age, but also on a patient’s activity level. These issues — together with the fact that increasing numbers of younger and more active people are receiving total joint replacement — have challenged the orthopaedic industry to try to extend the life cycle of total joint replacements.
