genu

 [je´nu] (pl. ge´nua) (L.)
genu extror´sum genu varum.
genu intror´sum genu valgum.
genu recurva´tum hyperextensibility of the knee joint.
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 va´rum an outward curvature of one or both lower limbs near the knee; see illustration. Called also bowleg.

For correction of genu valgum, a surgical procedure of medial close wedged osteotomy at distal end of femur was done.
It can be assumed that genu valgum can be a consequence of weight bearing by weakened bones.
In physiologic genu varum there is a gentle curve involving both the thigh and the leg with more pronounced bowing in the lower third of the femur and at the juncture of the middle and upper thirds of the tibia [17]; whereas in ligamentus hyperlaxity it is at the knee joint.
Next, inspect the gait and determine the foot progression angle; in genu varum the foot progression angle may be medial or normal.
The alignment of a child's leg changes during normal growth from genu varus up to 18 months to genu valgus up to 7 years of age.
The petrosal artery runs parallel to the greater superficial petrosal nerve and supplies the facial nerve at the area of its first genu and the labyrinthine segment.
2) Consequently, excessive tension was placed on the greater petrosal nerve, which passed over to the internal genu and resulted in the facial palsy.
