Orthopedics is dying, so don't use corrective instruments. What a waste of money. I studied orthopedics. I saw a girl during my internship. She had plastic surgery in a city hospital, and her O-leg was made into an X-shape. So I suggest you go to the best orthopedic hospital. Don't trust plastic surgery hospitals. Beijing jishuitan hospital is an authoritative orthopedic hospital in China. I suggest going there!
