How are O-legs formed?

O-leg is actually a disease called genu varus in medicine. Because of genu varus, the body weight will be concentrated on the articular surface inside the knee joint. The knee joint will wear out for a long time under the action of pressure and friction, and eventually there will be joint pain symptoms, which will affect normal walking. So how are O-legs formed?

There are two foundations for the formation of O-legs, one is calcium deficiency in the body, and the other is genetic factors, but there are also some direct reasons, such as walking splayed feet, relaxing standing posture, wearing shoes with heels of more than 5 cm, sitting on the board (kneeling) and squatting. , will bring outward strength to the knee joint, will continue to pull the lateral collateral ligament of the knee joint, causing relaxation.

The collateral ligament in the lateral position of the knee joint is an important stable structure of the whole knee joint. Once the lateral collateral ligament relaxes, it will affect the medial collateral ligament and cause abnormal symptoms, which will make the medial collateral ligament generate greater force and continuously pull the calf tibia to rotate inward, eventually leading to the knee joint turning inward into an O-shaped leg.

There are many reasons why babies have O-legs. The most common is rickets caused by vitamin D deficiency. In the early days, you will see that the baby has symptoms of sweating and shock. If not found and corrected in time, it will affect bone development and form O-legs. In addition, parents let the baby learn to walk too early, which is also one of the reasons for the baby's O-leg.
