genu val´gum a childhood deformity, developing gradually, in which the knees rub together or “knock” in walking and the ankles are far apart; the most common causes are irregularity in growth of the long bones of the lower limb (sometimes from injury to the bone ends at the knee) and weak ligaments. The weight of the body, which is not supported properly, turns the knees in and the weak lower legs buckle until the ankles are spread far apart. See illustration. Called also knock-knee.

Genu valgum in young children varies in seriousness. Milder cases may disappear after early childhood as bones, ligaments, and muscles strengthen and coordination improves. More serious cases can often be corrected by strengthening exercises and by proper manipulation of the joints. Sometimes braces are used to ensure the proper alignment of growing legs. In a very young child, genu valgum involves only the soft bone ends where the bone grows. If allowed to continue for a number of years, the condition can lead to abnormal developments in body structure. The sooner corrective measures are taken, the more effective the treatment is likely to be.
Genu varum and genu valgum. From Copstead and Banasik, 2000.

Genu varum


External deviation of the knee(s). A certain degree is normally present in infants, and corrects itself with bipedal ambulation; when excessive, rickets should be excluded, as vitamin D-induced osteomalacia may lead to bending of the femoral shaft bearing the mechanical brunt of ambulatory kinetics. When combined with anterior curvature of the tibia and fibula, affected children have a “saddle-sore” stance. Anterior or antero-lateral bowing of the tibia may occur in neurofibromatosis with fractures, and may be complicated by pseudoarthrosis .

genu varum

Bowleg Orthopedics A frontal plane deformity of the knee in which the distal tibia is directed towards the midline/median sagittal plane; GV is usually associated with coxa valga–the ankles are together and knees apart, and the Pt stands with feet together, knees separated and the tibias angled downward and inward. See Coxa valga.

ge·nu va·rum

(jē'nyū vā'rŭm)

genu varum

Bow or bandy legs. This is common and normal in healthy toddlers and usually corrects itself by about 18 months. Severe bowing can be caused by OSTEOCHONDROSIS of the main lower leg bone (the tibia) or by rickets. In these cases the condition can be cured by early treatment with night splints.

genu varum

; bowleg frontal-plane deformity characterized by lower-leg adduction (in relation to thigh), characterized by lateral loading of foot (if there is insufficient available subtalar and midtarsal compensatory pronation) or medial loading (if there is excessive available compensatory pronation at subtalar and midtarsal joints) in order to achieve a plantigrade position of the foot during stance
