Use of the VELYS Robotic-Assisted Solution in knee arthroplasty: A scoping review.
Review in Journal of experimental orthopaedics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Purpose: Robotic knee arthroplasty has been associated with improved knee-specific outcomes, but results are relatively immature. The VELYS Robotic-Assisted Solution is an imageless semi-active 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-surgery 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. Methods: A scoping review using five-stage methodology following Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) guidelines was undertaken. Articles were screened against pre-determined criteria, with data synthesized descriptively and thematically. Results: One hundred twenty-six 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-inferior safety profile. However, despite studies appearing to highlight favourable early patient-reported 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-term follow-up. Conclusion: The available literature regarding the VELYS Robotic-Assisted Solution is limited and of moderate-to-poor quality. Implant positioning was more accurate; however, other results, especially regarding improved patient outcomes, are not currently well-evidenced. Evidence was largely retrospective or early prospective, with no randomized controlled trials or long-term data. High-quality, randomized studies are required to evidence this technology. Level of Evidence: N/A.
