The reported outcomes of total hip arthroplasty (THA) for developmental dysplasia of the hip (DDH) varied widely because a wide range of deformities were included and different treating protocols and different materials were applied. The most common complications were dislocation, infection, and nerve palsy. The middle-term results are similar to ordinary THAs. But long-term results are compromised by young age of the patients, small cups, and conventional polyethylene insert. To reconstruct the acetabular cup at or near the anatomic level without lateral placement is better than a high center and lateral placement. Application of ceramic head, liner, and highly cross-linked polyethylene insert may improve the complications caused by wearing. Loosening and component wearing are the most common reasons for revision. A comprehensive planning is advised to face the problems of the cup, the stem, and the leg length discrepancy at revision.
