Background: Genu varum is the condition of the legs that bend inward, leading to walking disruptions. However, data on genu varum are still lacking to prevent the disease. This study aimed to identify the epidemiology of patients with genu varum in preventing, managing and determining the prognosis and as a source for future research.Methods: This research is a descriptive study using a retrospective research design. The sampling technique used is a total sampling of genu varum patients gained from the Department of Orthopedics and Traumatology database, medical records from Dr. Soetomo General Academic Hospital Surabaya, and patients' home visits. The target population is all genu varum patients from 2010-2018.Results: The total sample was 31 patients, 21 patients were male (67%), and 10 patients were female (32%). The average age of patients was 4.3 years. The first complaint of the disease was, on average, realized at 1.8 years. The birth weight data obtained an average of 3.49 kg. The average body mass index is 26.3. Langenskiold stage I,II,III,IV,V,VI type; 2 (3%), 43 (70%), 2 (3%), 5 (8%), 2 (3%), 8 (13%). Eighteen patients (58%) had bilateral Blount disease and 7 patients (22%) had unilateral Blount disease, and only six patients (20%) had physiologic genu varum. Eighteen patients were carried out conservative methods, and 13 underwent operative methods.Conclusion: Blount disease is the commonest cause of genu varum in Dr. Soetomo General Academic Hospital, specifically infantile. The highest number of patients are male and those who underwent operative treatment.
