Genu varum, commonly known as bow legs, is a condition where a person's legs curve outward at the knees while the feet remain close together. This results in a noticeable gap between the knees when standing. It can occur in children as a normal part of development, but in adults, it may be associated with conditions like arthritis or previous injuries. The severity of genu varum can vary, and it may lead to discomfort or difficulty in walking. Treatment options include physical therapy, braces for children, or surgery in more severe cases. Regular check-ups with a healthcare provider can help monitor the condition.
