 The early clinical and radiographic results of 184 total hip arthroplasty (THA) performed by a direct anterior approach (DAA) on consecutive patients with Crowe grade 2 to 4 developmental dysplasia were assessed. The mean duration of follow-up was 3.1 years. The mean JOA hip score improved from 42.4 preoperatively to 90.4 at the latest follow-up examination. Four cups were revised because of early migration due to initial fixation failure, however, no cup fixation failures occurred after the first 63 cases. Once the surgeon completes the learning curve, the DAA appears to be a safe and reproducible technique for THA on dysplastic hips, and to provide the reported advantages of DAA, including rapid recovery, correct implantation of the cup, and a low dislocation rate.
