Knock knee, medically known as Genu Valgum, is a condition characterized by a noticeable gap between the feet when standing with knees together. While it’s a common part of a child’s development, persistent or severe cases may indicate an underlying issue requiring treatment. In this article, we delve into the types, causes, symptoms, and treatment options for knock knees.

Types of Knock Knees


Typically observed in children aged 3 to 5, this is a natural part of development that often corrects itself by the age of 8.


Severe cases that persist beyond age 8 or develop in adulthood may be associated with underlying medical conditions such as obesity, vitamin D deficiency, or arthritis.
