Patient's question:
Newborns have genu varum, which approaches normal by the age of 2; after 2 years, they gradually develop genu valgum, and it returns to normal by the age of 10.Doctor's answer:
After the age of 10, most people will maintain normal or slightly varus (5 to 10 degrees) knees, which falls within the normal physiological range and does not require treatment. If there are still relatively severe symptoms of O-shaped legs after the age of 10, it is often caused by conditions such as rickets, epiphyseal injury, post-polio syndrome, arthritis, or developmental disorders, and should be treated as early as possible.
