Well, I know for a fact I have very short legs compared to rest of my body. Unfortunately, I feel like there have been multiple factors as to why I am short. I am just trying to get to an average height.
Not only that, the surgeon that I spoke with only allows 8cm on each bone as the max which I think is safe. Anymore than that may lead to serious complications down the road. I'd rather be safe than sorry. I am glad I found this site because when I first found LL and old forum years ago, I was one of those delusional people that thought I could just go for 12 to 13cm in one or 2 go's, not really aware of the potential consequences of that much lengthening. After reading on this site of the horror stories and finding out some of the so called "patient diaries" were fake diaries being used to promote certain surgeons, I found myself taking a step back and talking to other surgeons instead of the one's being promoted. The one I intend to go to is operating in Frankfurt as of now.
As far as 10cm+ goes, I am sure there are people who have done it but i'd rather be 5'8 1/2 than to try to make it to six feet tall. That to me would be unrealistic.
