Legg Calvé Perthes Disease
Prognosis for Legg Calvé Perthes Disease
Without treatment, the course is usually prolonged but self-limited (usually 2 to 3 years). When the disease eventually becomes quiescent, residual distortion of the femoral head and acetabulum predisposes to secondary degenerative osteoarthritis. With treatment, sequelae are less severe. Young children and children with less femoral head destruction when diagnosed have the best outcome.
