Background: Leg genu varum abnormalities may be unilateral, bilateral, or part of a windswept deformity; they are often accompanied by internal tibial torsion. Physiological bowlegs, rickets, infections, traumatic growth plate injuries, neoplasms, skeletal dysplasia’s, and Blount disease are among the many potential causes of genu varum deformities. Blount disease and rickets are common causes of genu varum deformities in Africa. Nevertheless, the precise prevalence of these disorders remains mostly unknown. Infantile Blount disease affects 37-62% of Caribbean babies, and one study puts the prevalence at 1/1200 live births. The incidence of rickets in various African countries ranges from 3% to 42%, highlighting the persistent nature of this health concern in emerging nations. Only 0.6% of children in a Gambia population survey had radiographic evidence of rickets, while 3.3% met clinical criteria for the disease. The most prevalent abnormality in this research was knock knee deformity (47%), followed by bilateral bow leg deformity (53%). The purpose of this review is to compare and contrast the functional, clinical, and radiological results of dome osteotomy with genu varum fixation using a T or L plate. In summary: The program takes into account the tibia's and femur's metaphyseal deformities when designing an automatic knee osteotomy. It then recommends the surgery with the right amount of opening to achieve the ideal mechanical axis without causing the joint lines to be too oblique. If the osteotomy of the proximal tibia is done within a certain range of deformity values, utilizing a defined procedure connected to a patented implant, it will provide favorable outcomes. A radically new method is necessary for the treatment of clearly visible Varus malformations. Corrective proximal tibial osteotomies for genu varum need thorough deformity analysis for surgeons to pick the right patients. Because of this, we may take the deformity's size and other features into account, which will lessen the likelihood of technical issues that might develop from correcting the patient utilizing the suggested method in conjunction with a custom implant.
