Bowlegs and Knock Knees in Children: Should you be Concerned?
It is common for children to have bowlegs when they are born. It may straighten out at 2 years, become knock knees at 4 and then become straight between 6 and 11.
Knock knees can vary in severity and timing depending on ethnicity and gender. Some children, for example, tend to straighten out their knees sooner after birth and may even get knock knees later. The knock knee angle is higher among girls than boys at all ages.
There are, however, some problems associated with knock knees. Most knock knees are considered normal, but further treatment is required if the angle is large or if it appears late or worsens with age.
