A three-year-old child’s inward curvature can be corrected through orthopedic exercises, customized orthopedic shoes, or surgical procedures. 1. With the help of parents or under the guidance of doctors in rehabilitation centers, 3-year-olds with mild inward curvature can strengthen their legs, arches and ankles to enhance local strength and improve their symptoms. 2. If the child goes to the hospital and asks the doctor to customize the orthopedic shoes according to the child’s own condition, together with the rehabilitation exercise, the symptoms can also be improved. 3. If the above treatments are not effective, surgical correction may be required. Whether or not a three-year-old child needs to be corrected for walking with an inward curvature needs to be determined by the clinician after the child has been examined in the hospital.
