How long do total knee replacements last for an active 45 year old before a revision is needed ?

Ballpark only: 10-15 years is the conservative lifespan--but some get decades, and some have failure issues after only a few years. Stay active and do not worry about uncontrollable things, you will be happier!

Varies: Based on recent data on all patient with surgery 12-15 years ago the cirrent estimate is that more than 80% will stii be in place at 20 years. Younger more active patients may not do as well . There are new materials awailable that show decreased wesr rates in the lab, it is not known if this will translate to clinical survival, but it may. There are many modes of failure besides "wearing out".
