genu valgum
Pronunciation: JEE-noo VAL-gum
A lower limb alignment condition where the knees angle inward, creating a 'knock-knee' appearance. Common in pediatric patients and may resolve spontaneously or require intervention.
Full Definition
Genu valgum, commonly known as 'knock-knee,' is a condition characterized by inward angulation of the knees, where the knees touch while the ankles remain apart. This condition follows a normal developmental pattern in children, typically appearing around age 2-3 years and usually resolving by age 7-8 years. The normal progression includes initial genu varum (bow-legs) in infancy, transitioning to genu valgum in toddlerhood, and finally achieving neutral alignment by school age. Pathological genu valgum may result from metabolic bone disease, growth plate injuries, or lateral growth disturbances. Severe cases with significant functional impairment may require surgical correction through guided growth techniques or osteotomy.
Usage
Usage note: Distinguish between physiologic (normal developmental) and pathologic genu valgum in documentation.
