The Harris hip score (HHS) was used to evaluate the clinical outcomes. Imaging was assessed by X-ray. Clinical failure was defined as postoperative total hip arthroplasty (THA) or the HHS was poor (&lt;\u200970). The Kaplan\u2013Meier survival curve was used to conduct a univariate analysis of risk factors. The analysis factors included gender, age, International Association Research Circulation Osseous (ARCO) stage, etiology, body mass index (BMI), 25-hydroxyvitamin D (25(OH)D), and type I collagen carboxy-terminal peptide (CTX).

The Harris score (76.29\u2009\u00b1\u200910.38) at the last follow-up was significantly higher than the preoperative HHS (64.45\u2009\u00b1\u20092.93) (\n                      <jats:italic>P<\/jats:italic>\n                      \u2009&lt;\u20090.05). The postoperative HHS was excellent with a success rate of 36.17%. Postoperative imaging evaluation showed that 9 hips improved, 28 hips stabilized, and 10 hips progressed. Moreover, 17 out of 47 hips were defined as a postoperative clinical failure and the success rate was 63.83%. 25(OH)D and preoperative ARCO stage were risk factors for postoperative clinical failure (\n                      <jats:italic>P<\/jats:italic>\n                      \u2009&lt;\u20090.05).
