To prevent the early onset of secondary osteoarthritis, rotational acetabular osteotomy has been proposed\n                      <jats:sup>1<\/jats:sup>\n                      .\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Description:<\/jats:title>\n                    <jats:p>The approach combines the anterior iliofemoral and posterior approaches through a single skin incision. The pubic bone is cut independently, and the ilium and ischium are cut in continuity. The rotation of the acetabulum provides a more horizontal weight-bearing area and, at the same time, returns the superiorly subluxated femoral head to a more normal position.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Alternatives:<\/jats:title>\n                    <jats:p>\n                      The Ganz periacetabular osteotomy involves the same concept as a rotational acetabular osteotomy with a different surgical approach. The rate of major complications, such as intra-articular osteotomy, nerve palsy, loss of fixation, malreduction, and symptomatic heterotopic ossification, is lower in rotational acetabular osteotomy (0% to 18%)\n                      <jats:sup>2<\/jats:sup>\n                      than in periacetabular osteotomy (6% to 37%)\n                      <jats:sup>3<\/jats:sup>\n                      . Because of a wide surgical exposure, osteotomy can be performed under direct vision in rotational acetabular osteotomy.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Rationale:<\/jats:title>\n                    <jats:p>Rotational acetabular osteotomy for osteoarthritis secondary to hip dysplasia can alter the position of the acetabulum en bloc and cover the femoral head with cartilage.
