I got one hip replaced in my thirties with titanium and ceramic. I am so glad I did it. I can't run too much but, beside that, I got back entire mobility after couple of months. More than 10 years have passed and it's like not having a prothesis. Ceramic was suggested by doctor as it lasts longer (though it's more fragile in case of accident).
Thank you for sharing that - it seems to be the rule that everyone I've talked to who has the surgery recommends it, though I have not known anyone who had it done in their 30's. My understanding is that ages are averaging down for a few reasons. I had a co-worker who had it done in his early 40's back at a time when that was nearly unheard of. He wore it out after 22 years but also had a successful revision. That was before ceramics or newer plastics so there's reason to believe that the current ones might last much longer, but it is still daunting facing the prospects of multiple surgeries; something I'm sure you must have grappled with.
