What it is Genu Valgum (knocked knee)
Knock knees is a condition in which the legs curve inward at the knees when in a straight position. Many young children have knock knees, which tend to be most obvious around the age of two to four. Though this can be a normal part of development, it normally resolved after age 7-8. When Genu Valgum presents in older children or adults, it may be a sign of other underlying conditions that need treatment.
