Soft tissues adaptation is the biggest issue in LL otherwise we could lengthen at rates of 0,5cm oer day and use a bone graft and gain 8cm in 2 weeks.
But if you do that you will not able to walk again.
You are completely ignorant and don't know even basic staff about LL. I hope you are never do LL because you will be completely ruined.
I see no reason or evidence soft tissues cannot adapt to extensive lengthening over longer periods of time. If you provided me with a study, I would definitely read it and make up my opinion accordingly. Otherwise, it is just fearmongering.
And yes, I plan to lengthen way over 16 cm in the span of couple years, so I don't live with regret of losing massive amount of money to become just slightly below average or average height.
People here who seriously consider lengthening 5 cm or so are hilarious, your life experience won't change in the slightest. And even if you do full 16 cm, it doesn't matter if you are like 5'1 or so, you will still be the short guy anywhere in the West, so you are just wasting your time and effort.
For really short people every inch counts and the shorter you are, the more you are willing to look past "muah my legs are 0.005 percent longer than my torso now" or "oh no i can't run a marathon in under 5 hours ahhh". Honestly, anyone who cares about proportions or biomechanics too much is either privileged enough not to be short enough or is just not serious about this surgery at all.
