Genoa valgus

Genua valga ( bowed knees ) are characterized by an increase in the physiological valgusity of the knee joints (one-/two-sided).

Genoa valgus

At the age of 3-4 years, this is a common finding.

Etiology

The reasons can be different:

• in children – hypoplasia of the lateral femoral condyle , chondrodystrophy , osteogenesis imperfecta , rickets , increased joint laxity, metabolic diseases, fractures,
• in adults – conditions after inflammation of the knee joint, intra-articular fractures, rheumatoid arthritis , arthrosis of the lateral joint surfaces.

Clinical manifestations

• the knees touch with their inner surfaces, the lower leg turns to the side → "legs in X" ,
• the medial condyle of the femur protrudes,
• often associated with a flexible planovalgus position of the foot .

Subjective difficulties

• tiring walking, difficulty running, retropatellar pain, ligamentous instability of the knee, cosmetics.

Size rating

• intermalleolar distance (IMD) – the distance between the inner ankles, physiologically up to 2 cm,
• angle between the longitudinal axes of the lower leg and femur,
• physiological valgusness of the knee joint averages 6 °.

Treatment

A finding in childhood usually resolves without treatment.

• With an IMD of around 8 cm → exercise , modification of shoes – increasing the sole on the inside of the shoe.

On failure → night splints  .

Operative treatment

• temporary growth arrest by medial hemiepiphysiodesis of the distal femur according to Blount  , supracondylar correction osteotomy of the femur.
