O-leg, also called internal knee roll and rotundity, is a physical defect. When the feet are together and the legs are fully relaxed and upright, if the two knee joints cannot come together between them, it means that there is an O-leg.
The standard leg shape should be in the aforementioned posture, with four contact points at the knee, mid-thigh, mid-calf, and ankle, and correspondingly, two diamond-shaped gaps above and below the knee joint. In the case of O-legged people, there is a large gap between the thighs, calves and knee joints, just like the shape of O. Therefore, it is commonly called O-legged.
1, O-legged harm O-legged will seriously affect the external image and temperament of people.
First of all, when the knee joints are upright, they can’t come together, which affects the height. And, from the front, it will look like the proportion of the leg is small. When viewed from the side, the proportions are more normal.
Secondly, people with O-shaped legs have swollen lower limbs because there is a gap between the legs and the outer contour of the legs is shifted outward. Adding to this performance, people with O-shaped legs tend to have more muscles on the outside of their large and small legs, and less muscles on the inside.
