The concept of individualised, functional implant positioning and how it relates to spinopelvic imbalance is an important yet rather novel consideration in THA. There is mounting evidence that a significant percentage of dislocations occur within the perceived \u201csafe zones\u201d; hence, in the challenging subset of patients with a stiff spinopelvic construct, it is imperative to employ individualised component positioning based on the patients\u2019 phenotype. Restoring the native centre of rotation, preserving offset, achieving the desired combined anteversion and avoiding leg length inequality are all very important surgeon-controlled variables that have been shown to be associated with postoperative outcomes. The latest version of the software has a feature of virtual range of motion (VROM), which preoperatively identifies potential dynamic causes of impingement that can cause instability. This review presents the workflow of RoTHA, especially focusing on pragmatic solutions to tackle the challenge of spinopelvic imbalance. Furthermore, it presents an overview of the existing evidence concerning RoTHA and touches upon future direction.<\/jats:p>","DOI":"10.3390\/medicina58111616","type":"journal-article","created":{"date-parts":[[2022,11,10]],"date-time":"2022-11-10T02:01:45Z","timestamp":1668045705000},"page":"1616","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":23,"title":["Robotic-Arm-Assisted Total Hip Arthroplasty: A Review of the Workflow, Outcomes and Its Role in Addressing the Challenge of Spinopelvic Imbalance"],"prefix":"10.3390","volume":"58","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0296-5909","authenticated-orcid":false,"given":"Andrew","family":"Ogilvie","sequence":"first","affiliation":[{"name":"Department of Trauma and Orthopaedic Surgery, University College Hospital, London NW1 2BU, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Woo Jae","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Trauma and Orthopaedic Surgery, University College Hospital, London NW1 2BU, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1056-2942","authenticated-orcid":false,"given":"Rhody David","family":"Asirvatham","sequence":"additional","affiliation":[{"name":"Department of Trauma and Orthopaedic Surgery, University College Hospital, London NW1 2BU, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5547-288X","authenticated-orcid":false,"given":"Andreas","family":"Fontalis","sequence":"additional","affiliation":[{"name":"Department of Trauma and Orthopaedic Surgery, University College Hospital, London NW1 2BU, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pierre","family":"Putzeys","sequence":"additional","affiliation":[{"name":"H\u00f4pitaux Robert Schuman, 2540 Luxembourg, Luxembourg"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fares S.","family":"Haddad","sequence":"additional","affiliation":[{"name":"Department of Trauma and Orthopaedic Surgery, University College Hospital, London NW1 2BU, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"866","DOI":"10.1302\/2058-5241.5.200037","article-title":"Robotics in total hip arthroplasty: A review of the evolution, application and evidence base","volume":"5","author":"Mart","year":"2020","journal-title":"EFORT Open Rev."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"6","DOI":"10.1016\/j.mporth.2021.11.002","article-title":"Robotic total hip arthroplasty: Past, present and future","volume":"36","author":"Fontalis","year":"2022","journal-title":"Orthop.
