Children who have had Legg-Calve-Perthes disease are at higher risk of developing hip arthritis in adulthood — particularly if the hip joint heals in an abnormal shape. If the hip bones don't fit together well after healing, this can cause the joint to wear out early. Hip replacement surgery eventually may be required.
In general, children who are diagnosed with Legg-Calve-Perthes after age 6 are more likely to develop hip problems later in life. The younger the child is, the better the chances for the hip joint healing in a normal, round shape.
