Yes, I met Dr Giotikas, and before had Skype consultation too, as you have to have a right connection with the doctor before making this decision. You seem to be in a very early stage on your possible journey, so only an advice, all your questions will be answered by a doctor, don't ask Q's, like what would you choose, because this operation is not a joke. On this forum 1% is a medical professional (or less), even me, as a doctor can't answer you precisely, as I'm not an ortophedic surgeon.
In my opinion this forum is very useful for basic infos (methods, doctors, supplements), and for reading solid, realistic diaries. The rest, like discussing clearly BDD (Body dimorphic disorder) standpoints as reliable opinions, or other projections are completely a waste of time, even misleading, if someone is new, and fresh in this topic, plus it takes time to realize the junk "information", additionally there is zero moderation on this forum as I see. I think (maybe I'm alone with this opinion) if someone didn't go through this (maybe only because of financial burden, it doesn't matter in this instance), and is not a professional, in 90% of cases is not a reliable source of info.
Long story short, read a lot (mainly publications Pubmed, Scholar, collections about the methods, supplements etc., and diaries), and ask after the doctor, or someone who has experience (I'm happy to answer these kind of Q's) more specifically (not to ask someone to decide which of your segments to choose, when your proportions, finance etc. are not even clear).
