DO NOT GO FOR TIBIA SURGERY. I will repeat myself! Complication rate for Tibia is higher no matter what other people are trying to tell you. Because of the alignment that easily can be screwed up between tibia and fibular espically if it is without a nail inside the bone. This can give you issues with walking without pain for the rest of your life, happens to many Tibia patients. Do you really wanna wear giant fixators for like 10 Months / 5 cm? Femurs heal faster, barely any chance of malalignment, and almost zero chance of you delevoping deep infections that can be deadly.
Summarize internal Femur: Safer, less complications, easier to hide, quickest. Almost any western doctor recommends internal femur over any external method including Rozbruch, Paley etc... And these are some of the best surgeons in the world!
AND THE MOST IMPORTANT PART OF ALL! You doing this surgery to gain as much height as possible and with the femurs you can get up to 8 cm safely, where for the tibias only 5 cm safely. Most who go over gets into serious complications unless there starting height is like 173+ cm.
