What is Medium-term Outcomes of Conventional Versus Short Uncemented Femoral Stems for Primary Total Hip Arthroplasty in Patients Younger Than 55 Years about?

## Background: Short stems are designed with a bone preservation philosophy in mind. This study aims to compare the outcomes/complications and survival of a collarless fully hydroxyapatite (HA)-coated conventional tapered stem and a HA-coated partial neck-retaining uncemented short stem in patients ⩽55 years old at medium-term follow-up. ## Methods: We retrospectively studied 247 uncemented THAs operated between 2010 and 2014, comparing 146 patients treated with the fully HA-coated collarless stem (Group A) with 101 patients treated with a partial neck preserving, HA-coated short stem (Group B). 87 and 62 males were in groups A and B, respectively ( p = 0.11). The mean age of the series was 46 years (17–55) ( p =0.16). The mean follow-up of groups A and B were 9.9 (7–12) years and 9.7 (7–12) years, respectively ( p =0.21). ## Results: Mean Harris Hip Score improved from 55 to 92 in group A ( p <0.001) and from 54 to 95 in group B ( p <0.001), without differences between groups. Mean femoral neck length preservation in groups A and B was 13.6 (0–28) mm and 26 (11–38) mm, respectively ( p =0.001). 13 (8.9%) and 1 (1%) patients in groups A and B presented postoperative complications,
