X-ray image of genua vara in rickets

Genua vara ( bent knees ) represent a very common deformity of childhood. They are normal in newborns. When the child begins to walk, the deformity becomes even more pronounced.

Etiology

• Rickets,
• conditions after fractures, inflammation and paralysis, Arthritis,
• Blount's disease – avascular necrosis of the medial part of the proximal metaphysis of the tibia.
• Fibrocartilaginous dysplasia ( unilateral ),
• deforming arthrosis ( adults ).

Clinical manifestations

• while standing upright, feet and ankles together, knees apart → "legs in O" .

Size rating

• intercondylar distance,

• the angle between the longitudinal axes of the Femur and lower leg.

Therapy

In children up to 2-3 years of age, the varus position of the knees is considered physiological. The adjustment usually occurs spontaneously.

For more severe deformities (intercondylar laxity around 10 cm), the boots are adjusted (increasing the outer edge of the sole). Night correction splints are applied to sleep.

In adulthood, a corrective osteotomy of the tibia can be performed to align the axis of the lower limb.
