What is the prognosis for children diagnosed with Perthes disease?

Fortunately, Perthes disease can respond well to treatment. In most cases, after two to five years of treatment/observation, many children can return to their normal activities without limitations. Children who develop Perthes disease who are six years old or younger have an excellent prognosis with observation alone.

A note from Cleveland Clinic

Although Perthes disease can’t be prevented, the good news is that treatments are available and they can be highly successful. Some children show no symptoms, others have mild pain and subtle symptoms. As the parent, be watchful of any change in your child’s walk or running mechanics or any evidence of a limp. If you see these changes, make an appointment to see your child’s healthcare provider.
