Some general knowledge of O-leg

“O-leg is a common deformity in China, which is not only a problem for beauty lovers, but also affects the future health. The most common reason for the formation of O-leg is that the two knees cannot come together when the feet are standing together naturally.

The most common reasons for the formation of O-leg can be divided into three categories: 1, developmental factors: during the development of the body due to malnutrition or intestinal diseases caused by a lack of calcium and phosphorus and other nutrients, bone development disorders, bone deformation or articular cartilage dysplasia, and changes in the knee inversion; 2, imbalance factors: due to long-term bad posture or incorrect force habits caused by the imbalance of the muscle mechanics governing the joint. Long-term imbalance in muscle mechanics can lead to joint displacement and the formation of internal knee rollover. This joint displacement is completely different from the familiar joint dislocation, which is the relative displacement of the two corresponding joint surfaces and the loss of the normal correspondence. This is caused by the overall rotation of the knee joint, not patellar subluxation, and as soon as the joint is corrected, the patella will return to the front. In general, the medial and lateral collateral ligaments of the knee are not the key factors in the formation of O-leg, but in some cases, such as trauma causing damage to the lateral collateral ligaments that destabilize the knee joint can also lead to O-leg.

In O-legged people, when standing and walking, the muscles on the outside of the leg usually exert force and the inside does not. Therefore, the muscles of the legs are not developed evenly, often with more muscles on the outside and less muscles on the inside. In this way, the formation of the leg muscle contour line is curved, giving the impression that the bones are bent. In fact, not all the bones are bent. If you want to determine whether the bone is bent, the most direct way is to take an X-ray orthopantomogram.

Also, some of the imbalanced O-leg is accompanied by the abduction of the hip joint, which will lead to a large gap between the legs. By understanding the causes of O-leg formation and the different types of O-leg, you can choose the right treatment method that suits you. The correct treatment for O-leg caused by developmental factors is surgery; for O-leg caused by other diseases, the primary disease should be treated first. Therefore, for most young people with O-leg, since the medial and lateral collateral ligaments of the knee joint are the stable structures of the medial and lateral angles of the knee joint, it is best not to try to correct O-leg by stretching the ligaments or forcibly squeezing the ligaments. It is very important to choose the treatment method carefully.
