Long-term follow-up of Legg-Perthes disease shows minimal functional impairment and symptoms even 30 to 48 years after onset.
May support reassuring long-term expectations in Legg-Perthes; leaves open confirmation in larger cohorts.
Thirty-six patients with Legg-Perthes disease were examined thirty to fortyeight years after the onset of symptoms. The average length of follow-up was 36.3 years. The typical patient had mild limp, minimum shortening, absent or mild hip pain, and minimum or no functional impairment with respect to his job and activities of daily living. Symptoms and functional impairment did not seem to increase with increasing age and length of follow-up.
