The mean age of the patients was 37.3\u2009years; 5 were men and 53 were women. All patients underwent THA through the posterolateral approach using the Pinnacle acetabular cup, a ceramic\u2010on\u2010ceramic bearing, and the modular S\u2010ROM stem. Subtrochanteric shortening osteotomy was performed on 86\/116 hips. Intraoperative conditions were recorded.

The mean operative time was 276.5\u2009\u00b1\u200957.9\u2009min (range, 175\u2013540). The mean intraoperative blood loss was 933.6\u2009\u00b1\u2009400.8\u2009mL (range, 300\u20132000). The mean transfusion requirement was 1778\u2009\u00b1\u2009798.0\u2009mL (range, 575\u20134550). The mean length of hospital stay was 8.6\u2009\u00b1\u20093.7\u2009days (range, 5\u201322). At the final follow\u2010up, no loosening of acetabular and femoral components was observed. No osteolysis and heterotopic ossification occurred.
