The aim of the study was to examine gait function pre\u2010 and postoperatively between CoC\u2010HRA, MoM\u2010HRA, and THA using subjective and objective measures with comparison to a healthy control group. Nineteen unilateral CoC\u2010HRA, 19 unilateral MoM\u2010HRA, and 18 unilateral THA gender, age, and BMI matched participants completed patient\u2010reported outcome measures (PROMs) (Oxford hip score [OHS] and metabolic equivalence of task score [MET]) and underwent gait analysis on an instrumented treadmill, preoperatively (2\u20138 weeks) and then postoperatively (40\u201352 weeks). Spatiotemporal measures and vertical ground reaction forces (GRF) were recorded. Statistical parametric mapping was used to detect differences in GRF between affected and nonaffected leg and to healthy controls. Preoperatively, there were no differences between groups in PROMs or objective measures. All groups showed an improved OHS postoperatively with only CoC\u2010HRA and MoM\u2010HRA demonstrating significant increase in MET. Postoperatively, TWS in both HRA groups improved with no difference to CON while THA was unable to demonstrate improvements. Postoperatively, at 6.5\u2009km\/h, THA demonstrated an asymmetric GRF profile, whereas CoC\u2010HRA and MoM\u2010HRA showed no differences between legs. In comparison of the affected leg GRF, THA demonstrated a weaker push off when compared to both resurfacing groups and CON. CoC\u2010HRA and MoM\u2010HRA showed no significant differences to CON. CoC\u2010HRA emerges as a potential alternative to MoM\u2010HRA, effectively addressing metal ion release concerns while retaining similar functional benefits.<\/jats:p>","DOI":"10.1002\/jor.70112","type":"journal-article","created":{"date-parts":[[2026,1,7]],"date-time":"2026-01-07T17:47:07Z","timestamp":1767808027000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["The Effect of Hip Arthroplasty on Gait Function: Comparison of Ceramic\u2010On\u2010Ceramic Hip Resurfacing, Metal\u2010On\u2010Metal Hip Resurfacing, and Total Hip Arthroplasty"],"prefix":"10.1002","volume":"44","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-1199-4592","authenticated-orcid":false,"given":"Dylan","family":"Leon","sequence":"first","affiliation":[{"name":"Imperial College London Sir Michael Uren Hub London UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Amy","family":"Maslivec","sequence":"additional","affiliation":[{"name":"Imperial College London Sir Michael Uren Hub London UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Brogan","family":"Guest","sequence":"additional","affiliation":[{"name":"Imperial College London Sir Michael Uren Hub London UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Natasha","family":"Allott","sequence":"additional","affiliation":[{"name":"Imperial College London Sir Michael Uren Hub London UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Justin","family":"Cobb","sequence":"additional","affiliation":[{"name":"Imperial College London Sir Michael Uren Hub London UK"},{"name":"Embody Orthopaedic Limited, Sir Michael Uren Hub London UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2026,1,7]]},"reference":[{"key":"e_1_2_7_2_1","article-title":"Global, Regional, and National Burden of Osteoarthritis, 1990\u20102020 and Projections to 2050: A Systematic Analysis for the Global Burden of Disease Study 2021","volume":"59","author":"GBD 2021 Osteoarthritis Collaborators","year":"2023","journal-title":"Lancet Rheumatology"},{"key":"e_1_2_7_3_1","volume-title":"The National Joint Registry 19th Annual Report 2022","author":"Ben\u2010Shlomo Y.","year":"2022"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(18)31859-2"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(18)31665-9"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1249\/MSS.0000000000003365"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.2106\/JBJS.20.01679"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.2106\/JBJS.G.01012"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1080\/17453674.2019.1594096"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11999-009-0938-z"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00264-010-1040-6"},{"key":"e_1_2_7_12_1","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.101B11.BJJ-2019-0383.R1"},{"key":"e_1_2_7_13_1","first-page":"164","article-title":"Adverse Reaction to Metal Debris Following Hip Resurfacing: The Influence of Component Type, Orientation and Volumetric Wear","volume":"93","author":"Langton D.
