Despite appropriate treatment, secondary hip osteoarthritis may develop after Legg-Calvé-Perthes disease at a relatively younger age. Total hip arthroplasty is safe and efficient method for the treatment of sequelae after Legg- Calvé-Perthes disease. Implementation of today`s conventional total hip arthroplasty after Legg-Calvé-Perthes disease produces similar success rates as total hip arthroplasty after primary osteoarthritis of the hip. However, according to literature, larger series report higher rates of neurologic complications and peri-prosthetic fractures. Residual coxa breva, a typical deformity seen after Legg- Calvé-Perthes disease involves short femoral neck, relatively overgrown trochanter major, larger femoral head and decreased neck-shaft angle. However, the femoral diaphysis is often unaffected and allows the placement of conventional prostheses. On the other hand, the acetabulum is often shallow, has lost its concavity and adapted to the femur. But it has enough medial wall for placement of a hemispherical component. Some reports suggest using modular or custom made components. Specifically, the size and shape mismatch between metaphysis and diaphysis is aimed at here. The results of these series are also similar to those of total hip prosthesis after primary osteoarthritis.
