Bow legs, also known as genu varum, is a physical condition that describes an outward curvature of the legs, resulting in a distinct bow shape that can affect an individual's mobility and balance. The following are some synonyms that are commonly used in place of the term bow leg: knock-knee, bandy-legged, curved leg, bent leg, cow-hocked, and sabre-legged. These terms are often used interchangeably and describe similar physical characteristics, which make the legs appear "bent" or "curved" in shape. Bow legs can be caused by several reasons and can be corrected using orthopedic devices, exercises, or surgical procedures depending on the severity of the condition.
