Knock knees is a condition in which the legs curve inward at the knees. When a child stands, the knees appear to bend toward each other and the ankles are spread apart.

Knock knees most often develop as a part of normal growth. In some cases, especially if the child is 6 years of age or older, knock-knees may occur as a result of other medical problems such as injury of the shin bone, osteomyelitis (bone infection), overweight, and rickets.
