According to the data of China Leg Plastic Surgery Center, there are countless patients with O-legs all over the country, but there are very few cases of O-legs caused by bone bending. Almost everyone has light or heavy O-legs in their legs, and many beauty seekers who think they are O-legs have also been to regular hospitals for X-rays. The result is that the bones don't bend at all, and the main reason why the legs are not straight is the lack of soft tissue or asymmetry, that is to say, people with straight legs have a lot of fat in this curved place, so they are straight, while people with bent legs lack fat in this place, so they bend.

Therefore, autologous fat transplantation to correct O-leg is not a palliative, but a minimally invasive method to fundamentally correct O-leg once and for all.
