Stretching little is it possible to get a 100% recovery to play sports?

Edit Post

Hello everyone, I have 174cm of height and 185cm of wingspan. I want to get a real gain of 5cm (it would be necessary to lengthen how many cm? 6?) Making tibia and femur (2.5cm or 3cm in each), it seems a safe size and I will be satisfied with 179cm of height. And the correction of genu varum.
    I wonder if 100% recovery is possible because i would like to be able to play sports such as football and cycling? And if possible, what is the total recovery time? Which doctors are most recommended for my situation (I mean Paley from experience)?

   Thank you in advance and forgive me for English because I am not a native of that language.

I'm from Brazil, but in my family all men are taller than me (on average 180 cm). I think about making 3cm in each member
