Legg-Calvé-Perthes disease is a similar condition seen in children and adolescents.

On the contrary, Legg-Calvé-Perthes disease frequently results in a deformed femoral head that leads to arthritis and the need for joint replacement.

At 5, Mr. Shannon learned that he had Legg-Calvé-Perthes disease, a degenerative condition affecting the hips.

Avascular necrosis of the femoral head (Legg-Calvé-Perthes disease) typically occurs in children aged 4-8, and is also more common in boys.

Some, notably Kienbock's disease of the wrist, may involve considerable swelling, and Legg-Calvé-Perthes disease of the hip causes the victim to limp.

There was also some controversy about whether continuous high intra-articular pressure in transient synovitis could cause avascular necrosis of the femoral head (Legg-Calvé-Perthes disease), but further studies did not confirm any link between the two conditions.
