A varus deformity is defined as:

1. Knees bent outward - bowlegged

2. Knees bent inward - knee knocked

3. Knees straight - normal alignment

4. Knees locked in extension

The correct answer is: Knees bent outward - bowlegged

A varus deformity is characterized by the outward bending of the knees, leading to a bowlegged appearance. This alignment occurs when the angle between the femur and tibia at the knee is less than normal, resulting in the lower extremities appearing to diverge from the midline of the body. In a varus deformity, the knees do not align directly beneath the hips, which can lead to an increased pressure on the outer part of the knee joint. Understanding this concept is crucial, as varus deformities can have implications for the function and mechanics of walking and running, potentially leading to complications or discomfort over time. The other descriptions do not accurately represent varus; the inward bending of the knees refers to a valgus deformity, while locked knees and normal alignment describe different conditions or postures entirely.
