We hypothesized that the anatomical design of the H1 cup would reduce the need for medialization to avoid rim overhang, thereby preserving acetabular bone stock. A retrospective three\u2010dimensional simulation study was performed in 12 hips with osteoarthritis and femoral head size \u2265\u200948\u2009mm. H1HR and BHR were virtually implanted using 3D planning software to minimize the risk of groin pain. The primary outcome was the volume of acetabular bone resection. Secondary outcomes included the position of the cup relative to the native hip centre and the cup non\u2010coverage ratio. H1 cups required a mean volume of acetabular bone resection of 11\u2009cm\n                    <jats:sup>3<\/jats:sup>\n                    , while BHR cups required 17\u2009cm\n                    <jats:sup>3<\/jats:sup>\n                    . This 35% reduction was statistically significant. H1 cups had less medialization (\u22121\u2009mm vs. \u22126\u2009mm), superior displacement (\u22121\u2009mm vs. \u22122\u2009mm), and posterior displacement (\u22121\u2009mm vs. \u22123\u2009mm). The mean cup non\u2010coverage ratio was not significantly different (10% vs. 8%). The anatomically designed H1HR achieved a significant 35% reduction in acetabular bone resection compared with BHR. This substantial volume of bone preservation was primarily attributed to the design enabling cup placement with minimal medialization, without increasing the cup non\u2010coverage ratio. Although further validation in cadaveric or postoperative imaging studies is needed, H1 may be a promising option for bone preservation, particularly for young, active patients who might require future revision surgery.\n                  <\/jats:p>","DOI":"10.1002\/jor.70221","type":"journal-article","created":{"date-parts":[[2026,5,7]],"date-time":"2026-05-07T07:17:14Z","timestamp":1778138234000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Acetabular Bone Preservation in H1 Ceramic Hip Resurfacing: A Comparison With A Conventional Metal\u2010on\u2010Metal Hip Resurfacing"],"prefix":"10.1002","volume":"44","author":[{"given":"Yuki","family":"Yamamuro","sequence":"first","affiliation":[{"name":"MSk Lab Imperial College London London UK"},{"name":"Department of Orthopaedic Surgery Kanazawa University Kanazawa Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Simon","family":"Harris","sequence":"additional","affiliation":[{"name":"MSk Lab Imperial College London London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rima","family":"Nasser","sequence":"additional","affiliation":[{"name":"MSk Lab Imperial College London London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amir","family":"Ardakani","sequence":"additional","affiliation":[{"name":"MSk Lab Imperial College London London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Justin","family":"Cobb","sequence":"additional","affiliation":[{"name":"MSk Lab Imperial College London London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,5,7]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jor.2020.12.036"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1080\/17453674.2019.1594096"},{"issue":"10","key":"e_1_2_9_4_1","first-page":"1186","article-title":"Effects of Physical Activity on Long\u2010Term Survivorship After Metal\u2010On\u2010Metal Hip Resurfacing Arthroplasty: Is It Safe to Return to Sports?","volume":"101","author":"Amstutz H.
