I am Chinese so my English will be not so good, sorry.

I have realized that it's relatively feasible and safe to gain about 5-6cm by surgery, because there are so much pictures on the internet.

But it seems much more difficult to gain 10cm by surgery, even if I undertake surgery twice. I scarcely saw picture or article about people who really gain 10cm.

Some surgeons claim it's possible to gain 16cm if you undertake more than once surgery.(FOR EXAMPLE femur 6+ tibia 7+ femur  3 )

I think gaining 16cm would be too greedy, I consider gaining 10cm is enough to me. More than once surgery will be affordable to me.

How do you think?
