Limb lengthening surgery in Germany

I am Chinese, but unfortunately my height is only 65.4 inches, which is a relatively low height in Asia. Please ask my friends, how should I choose a doctor? I plan to have surgery to 67.7 inches and I want to be safe. After all, there are a lot of accidents in Asia and Turkey. I would like to ask which hospital in Germany is safe and the sports ability has been restored as much as possible. Thank you.
