Final answer:
Genu varum, or bow-leggedness, is the movement impairment where the knees bow outward. It can be caused by various conditions and may require different treatment options.
Step-by-step explanation:
Knees bowing outward is a movement impairment known as genu varum, also called bow-leggedness. It is commonly seen in various conditions such as osteoarthritis, rickets, and Blount's disease.
In genu varum, the knees are positioned away from each other, causing a gap between the ankles when the feet are together. This can lead to an abnormal walking gait and potential complications.
Treatment for genu varum depends on the underlying cause and severity. It may involve physical therapy, orthotic devices, or in some cases, surgical intervention.
