Knock knees: 
Genu valgum is an angular deformity of the knee, often treated surgically by osteotomy or by growth modulation (using tension band, staples, transphyseal screws and eight-plate which require removal after correction). With this study, we attempt to evaluate the efficacy, rate of correction and complications with the use of 8-plate in the correction of genu valgum deformity in children.

Material and method:
In a retrospective study of 24 patients with 11 bilateral and 13 unilateral (35 knees) genu valgum deformity which required surgical corrections were included. There were 11 males, and 13 females and all of them were treated with Steven’s technique (Stevens, 2006) using eight-plate and monitored closely.

Result:
Twenty-four patients with an average age of 10 years and 8 months (range: 5 yrs, 7 months–14 yrs, 2 months), with the mean preoperative & post-implant removal (Post-IR) tibiofemoral angle of 22.02° ± 5.15° (range 14°–31°) & 6.14° ± 1.92° (range 2°–10°) respectively, required an average time period of 1yr & 5m ± 5 m (range 10 months–28 months) for correction after which implants were removed. Of the 35 limbs, we achieved excellent results in 91.6%. One case (4.16%) had a partial correction of the deformity, and one case (4.16%) had reported a superficial infection which was taken care of. There were 2 cases (8.33%) of over-correction, which was gradually self-corrected during follow-up.

Conclusion:
Our results reflect the efficacy of the flexible titanium eight plates which corrects angular deformity by acting as a tension band on one side of the growth plate and offers the advantage of reversible Hemi epiphyseal growth modulation. Guided growth modulation is the best available alternative for the treatment of an angular deformity in the patients with open physis.

Bow Legs:  Bow leg (varus knee) is a condition in which one or both knees of a child are bent outward. This allows more space than usual between the knee and lower leg. Keep your knees wide apart when your child is standing with their feet and ankles together. Children’s feet can look like arches, especially when walking.
Who will get the bowleg?   Bow legs are common in infants. The condition is rarely serious. Babies born with bow legs usually outgrow the condition by the time they are 18 months old. Bow legs can also occur in older children. These cases should be evaluated by a healthcare provider. symptoms and causes

What causes a baby’s leg to bend? Bow legs occur for a variety of reasons. The most common cause of bow legs is a condition called physiological club knee. When the fetus was developing inside the womb, the uterus was in a cramped position. Some of the fetal bones had to rotate inside the uterus to fit into the small space. Physiological varus knees are just your child going through a normal developmental process. These include:

Brandt’s disease. Blount’s disease (inner tibia) is a growth disorder caused by problems with the growth plate of the tibia in children. Brandt’s disease is more common in African-American children, overweight children, and children who walk fast. rickets. Rickets is caused by a deficiency of calcium or vitamin D. Deficiency of these important nutrients causes children’s bones to become soft and weak and their legs to bend. Rickets is very rare in the United States but remains common in developing countries. Short stature The most common type of dwarfism is caused by a defect in bone growth called achondroplasia. This disorder can cause bowlegs and other bone problems. Bow legs can occur when fractures do not heal properly and bones develop abnormally (osteodysplasia). Fluoride or lead poisoning.
