Legg-Calve-Perthes Disease: Follow-up
Updated: Jan 27, 2009
Outcome and Prognosis
The prognosis for patients with Legg-Calvé-Perthes disease can be good and depends on the completeness of involvement of the epiphyseal center. The severity of involvement of the femoral head, its subsequent healing, and proper joint space preservation all determine the degree and timing for an athlete to participate in sports. The functional result depends on the amount of deformity that develops when the structure is softened. Overall, the prognosis for recovery and sports participation after treatment is very good for most individuals.
The patient's short-term prognosis is related to femoral head deformity at the completion of the healing stage. Risk factors include a clinical onset at an older age, extensive femoral epiphyseal involvement, femoral head containment, reduced range of motion in the hip, and premature closure of the growth plate.
The long-term prognosis is related to the potential for osteoarthritis of the hip as an adult. In patients with metaphyseal defects, in those in whom the disease develops late in childhood (age 10 y or older), and in those who have more complex involvement of the femoral head with residual deformity, the prognosis is worse, and degenerative arthritis occurs in nearly 100% of these patients. This rate is in comparison to those patients who are younger than 5 years when the problem develops. The incidence of degenerative arthritis is negligible in this younger population.
