The VELYS Robotic\u2010Assisted Solution is an imageless semi\u2010active system used with the ATTUNE knee arthroplasty system. Recently, the UK National Institute for Health and Care Excellence called for a multidomain evaluation of six robotic\u2010surgery platforms in orthopaedics, of which VELYS is one. This review aimed to (i) evaluate current evidence on VELYS in total knee arthroplasty, (ii) assess outcomes, complications, cost and versatility, (iii) appraise study quality and (iv) identify knowledge gaps.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A scoping review using five\u2010stage methodology following Preferred Reporting Items for Systematic Reviews and Meta\u2010Analyses extension for Scoping Reviews (PRISMA\u2010ScR) guidelines was undertaken. Articles were screened against pre\u2010determined criteria, with data synthesized descriptively and thematically.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>One hundred twenty\u2010six studies were identified, with 22 included. Evidence level ranged from II to IV. Analysis highlighted improved implant positioning as seen with other robotic systems, as well as a non\u2010inferior safety profile. However, despite studies appearing to highlight favourable early patient\u2010reported outcomes and function as well as greater workflow efficiency, the overall quality of the published work was poor, giving little evidence to robustly support many of the conclusions drawn in these studies. Limitations of these studies included small sample sizes, a lack of information on patient characteristics and patient selection, retrospective design and a lack of long\u2010term follow\u2010up.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The available literature regarding the VELYS Robotic\u2010Assisted Solution is limited and of moderate\u2010to\u2010poor quality. Implant positioning was more accurate; however, other results, especially regarding improved patient outcomes, are not currently well\u2010evidenced. Evidence was largely retrospective or early prospective, with no randomized controlled trials or long\u2010term data. High\u2010quality, randomized studies are required to evidence this technology.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Level of
