What is the term for a 'bow-legged' condition?

The term 'bow-legged' refers to a condition known as genu varum. In this condition, the legs appear to curve outward at the knees while the feet and ankles remain closer together, creating a noticeable gap between the knees when standing. This distinctive outward curvature is what defines bow-leggedness.

Genu varum can arise due to various factors, such as genetic predisposition, certain medical conditions, or nutritional deficiencies in childhood. Understanding this condition is crucial in sports medicine as it can affect an individual's biomechanics and potentially lead to joint issues or injuries if not properly addressed.

Other options refer to different conditions. Genu valgum, often known as 'knock-knees,' describes legs that curve inward. Genu flexum refers to a flexed knee condition that can limit extension. Genu rectum, while not commonly used in medical terminology, would imply straight legs, which is not related to the bow-legged condition. Thus, the correct term for a 'bow-legged' condition is indeed genu varum.
