Congenital orthopedic knee deformities in children are a reality. The age of onset of these deformities coincides with the age of walking, and both sexes are affected, with a predominance of males.Genu valgum and genu varum make up the majority of congenital orthopedic knee deformities in children, with a slight predominance of genu valgum over genu varum. Most knee deformities are bilateral. Knee deformities are almost always isolated, but certain anomalies such as flat feet and knee rigidity are recorded.Parents, especially in the Bujumbura area, are beginning to understand the value of consulting centers for the treatment of these deformities, once they have been identified. However, these centers are still insufficient in our country.Rehabilitation of congenital orthopedic knee deformities gives very good results if it is started early and if protocols are followed. Nevertheless, there is no shortage of failures in the correction of these deformities, caused by late onset of treatment and non-compliance with treatment protocols.
