O-leg, scientific name genu varus, refers to the defect that there is a gap between the knees when the feet are together and relaxed. Generally speaking, standing with feet side by side, ankles together and knees apart 10 cm or more is an O-shaped leg. O-leg is caused by congenital developmental or degenerative arthritis. It doesn't matter if adults have mild O-legs. After all, no one is perfect. If you want to treat them, you need surgery. Unlike children, adult bones cannot be corrected by non-surgical methods.

O-leg is a kind of defect that seriously affects people's figure. According to our market survey, O-shaped legs are uglier than obesity, accounting for 30%, which affects people's external beauty as much as obesity, accounting for 40%. For college students, O-legs may affect their future employment and love, and have a great negative psychological impact. Therefore, the desire to correct O-legs is generally strong. As long as the effect of correcting products is accurate and the price is reasonable, it is not difficult to turn potential demand into actual purchase behavior. The proportion of O-legs in the crowd is about 35%. /kloc-the proportion of O-legs among young people aged 0/8 ~ 22 is about 30%.

Surgical correction of O-legs is suitable for the following situations:

1, O-shaped legs really affect the appearance, you can't wear skirts in summer, you don't walk gracefully, and your height is a little shorter than others. 2. Severe O-leg will change the load-bearing line and negative focus of the upper and lower joints, leading to premature joint degeneration and osteoarthritis, which is also the greatest harm brought by O-leg. After surgical correction, the upper and lower joints can return to normal force lines.

Expert tip: If you decide to have surgery, you must go to a regular hospital for detailed consultation and examination. At the same time, the following points should be considered: 1. Although osteotomy is a mature routine operation, if the operation is not standardized, complications may occur, such as poor fracture healing or poor osteotomy position, affecting the articular surface or causing nerve damage.

2. If the O-leg is not very serious, but only affects the appearance, then surgery is not recommended. Orthopedic osteotomy will inevitably leave surgical edges and scars, which will affect the beauty of patients (especially women). In addition, after corrective surgery, bone healing takes several months.

3. If the correction is too early, with the growth and development, there is the possibility of a second operation. It is suggested that the operation should be performed after the growth and development stop. Usually, the O-leg is caused by the bending of the tibia, so the general corrective operation is the valgus osteotomy of the upper end of the tibia. The so-called eversion osteotomy refers to removing an outer triangle, and then combining the bones on both sides to correct the O-shaped leg.

There are several operations to correct the O-shaped leg, depending on the deformed shape of the O-shaped leg, and the commonly used ones are as follows: 1. Inverted U-shaped osteotomy of tibial tubercle and external fixation with tubular plaster after operation. 2. External fixator plus inverted U-shaped osteotomy of tibial tubercle. The advantages of this method are simple and safe osteotomy, fast bone healing and not easy to delay healing. The use of external fixator is convenient to master the angle of plastic correction, which can make the angle of bone healing accurate and convenient to adjust; Patients can move on the ground during the treatment, and the muscles of lower limbs will not atrophy. According to statistics, the complete correction rate of deformity can reach more than 96%. The disadvantage is high cost.
