Hi, I am a tyro here and I have been reading the contents  for days. But still I have several questions and want get a relatively pertinent answer.       
      For starters, the concept of best is different by everyone. In my case, I am now 168cm, and would like to gain 7cm more. However, I also want to obtain my athletic abilities as much as possible. At least 90%_95% I would say. My current plan is to get a 3+4 surgery.

1. Is there a difference in recovering moving abilities between femur and tibia surgery? Rumors haven been heard that the patients who did femur surgery obtain more athletic abilities.

2. Will do 7cm in tibia or femur better than 3+4 or even worse?

3. If the single surgery in tibia and femur would keep 90% abilities, would doing them both mean that I would only obtain 0.9*0.9~0.8 abilities?

4. Rarely have people uploaded their athletic abilities test here. Is there any data or treatise that I can get? Just want to know how fast can people run in 100m test and 1000m test on average when they are recovered
5. I am now living in China where only external surgery is provided. Do you suggest me to do the surgery here or somewhere in Europe where I might cost all my lifesavings. Will the effect be different in external and internal cases if the surgeries are successful. Also, I have seen advertisements from Turkey. Are they a good choice?

You reply would be rather important for me and I would really appreciate it.
