Hello,

I am a soon to be 19yo male and around 168-169cm. There is a chance I have some sort of spinal curvature issue (not verified, will check with doctor soon), and if fixed I imagine that will give me 1-2cm more, so I would be 171cm at most. Regardless, I doubt I will grow anymore considering my age, my parents heights (5'5" and 4'11"), and the fact that I haven't grown at all since I was around 16. My height brings me a lot of distress, so I plan to get limb lengthening.
I have a few questions regarding the process.
What is the maximum height increase I can gain while still maintaining athletic ability and mobility? I am aware I will not retain 100%, but a high amount still (maybe 90-95%).
I want to be minimum 174cm, and obviously ideally the taller the better.

What would the differences between lengthening femur and tibia be? Would it be a good idea to say, increase 3 cm in both, as opposed to 6cm in just my femur?

Some physical activities I partake in and would like to continue after LL are combat sports, swimming, hiking, and skiing. Anyone with any experience in these after LL know if I can resume?

Who are the best and most reliable doctors? Money is not a concern for me, but I am based in the US. Obviously cheaper is better but I'm willing to pay whatever's necessary due to how life altering this surgery is.
