<jats:title>Introduction</jats:title>
<jats:p>The present study evaluated whether patient demographic characteristics influence the subsidence of the stem in total hip arthroplasty (THA). The following characteristics were evaluated: age, height, weight, and sex. The association between the time elapsed from the THA implantation and the amount of stem subsidence was also investigated.</jats:p>

<jats:title>Methods</jats:title>
<jats:p>The records of patients who underwent THA in the period between 2016 and 2023 were accessed. All patients underwent two-staged bilateral THA using cementless DePuy collarless Corail (DePuy Synthes, Raynham, MA, USA) stems. The following parameters were measured and compared to assess stem subsidence: distance from the proximal femur at the stem bone interface and the medial apex of the regular triangle built within the trochanter minor (point A); distance from the medial apex of the regular triangle built within the trochanter minor and the distal portion of the femoral stem (point B).</jats:p>

<jats:title>Results</jats:title>
<jats:p>Overall, 294 patients were included. 62% (182 of 294 patients) were women. 45% (134 of 296 THAs) were on the right side. The mean age was 64.9 ± 10.4 years. The mean BMI was 28.3 ± 5.1 kg/m<jats:sup>2</jats:sup>. The mean length of the follow-up was 14.4 ± 11.0 months. The mean subsidence in point A was 2.1 mm (<jats:italic>P</jats:italic> < 0.0001), and that in point B was 3.1 mm (<jats:italic>P</jats:italic> < 0.0001). There was evidence of a weak positive association between patient weight (<jats:italic>P</jats:italic> < 0.0001), age (<jats:italic>P</jats:italic> = 0.03), follow-up (<jats:italic>P</jats:italic> = 0.002) and the amount of stem subsidence. Patient height did not demonstrate any association with the amount of stem subsidence (<jats:italic>P</jats:italic> = 0.07). There was no difference in stem subsidence between women and men (<jats:italic>P</jats:italic> = 0.9).</jats:p>

<jats:title>Conclusion</jats:title>
<jats:p>Stem subsidence in THA using cementless DePuy collarless Corail implants is approximately 2.6 mm after 14.4 months. Greater patient weight, age, and longer time elapsed from THA implantation were associated with greater stem subsidence. Patient height and sex did not demonstrate any influence on the amount of stem subsidence. These results must be considered in light of the limitations of the present study.</jats:p>
