| Summary: | The aim of this study was to evaluate the outcomes of Total hip arthroplasty (THA) performed for hip osteoarthritis caused by Hartofilakidis type 2 and 3 developmental dysplasia of the hip (DDH) and to compare these two types in terms of clinical scores. Thirty-six hips of thirty patients who suffered from hip osteoarthritis caused by DDH and who underwent THA operations from January 2005 to May 2010 were included in the study. In the case of insufficient coverage of the acetabular cup, roof reconstruction was performed using femoral head autografts. Subtrochanteric transverse femoral osteotomy was performed when required. Clinical evaluations were performed using Harris Hip Score (HHS). 3 male and 27 female patients were included in this study. Mean age was 57.2 (25-76) years. Mean follow up time was 34.3 (1265) months. 24 hips were classified as Hartofiladikis type 2, and 12 as type 3. HHS was 43.2 (38-54) points and 90.1 (76-96) points at the preoperative and postoperative last control visits, respectively (p [Med-Science 2018; 7(2.000): 378-82]
