Which condition involves knees that are aligned closer together than ankles?

The condition where the knees are aligned closer together than the ankles is known as genu valgum, commonly referred to as "knock-knees." In this alignment, the femurs angle inward, causing the knees to touch or be closer together while the feet remain apart. This can lead to an abnormal gait and increased stress on the knee joints, potentially resulting in discomfort or other complications over time.

Genu valgum is typically identified in children and may correct itself as they grow, though in some instances, medical intervention may be necessary to manage severe cases. This condition contrasts with genu varum (bowlegs), where the knees are farther apart than the ankles, and coxa vara or coxa valga, which refer to conditions involving the hip and the angle of inclination of the femur with respect to the pelvis. Understanding these terms is essential for correctly identifying these orthopedic conditions and their implications for patient care.
