Previous PSI meta-analyses of TKA outcomes typically do not differentiate between PSI systems and assess relatively few outcomes, so the value of their findings is limited. VISIONAIRE<jats:sup>\u2122<\/jats:sup> cutting guides (Smith\u2009+\u2009Nephew Inc., Memphis, TN, USA) is a PSI system based on preoperative magnetic resonance and X-ray imaging. A systematic literature review (SLR) and meta-analysis, focussed specifically on VISIONAIRE, were conducted to assess TKA accuracy, intraoperative outcomes, and postoperative outcomes, compared with conventional instrumentation (CI).<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Materials and methods<\/jats:title>\n                <jats:p>The SLR was performed using PubMed, Embase, and Google Scholar databases to identify relevant studies published until March 2022. Depending on statistical heterogeneity, meta-analyses were performed for outcome measures with fixed effect (<jats:italic>I<\/jats:italic><jats:sup>2<\/jats:sup>\u2009&lt;\u200950%) or random-effects models (<jats:italic>I<\/jats:italic><jats:sup>2<\/jats:sup>\u2009\u2265\u200950%).

Compared with CI, VISIONAIRE reduced odds of mechanical outliers by 40% (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.0001), with no statistically significant differences in odds of overall coronal, sagittal, or rotational plane component outliers. VISIONAIRE improved surgical efficiency (operating room, turnover, and tourniquet times reduced by 7.3% (<jats:italic>p<\/jats:italic>\u2009=\u20090.02), 42% (<jats:italic>p<\/jats:italic>\u2009=\u20090.022), and 15.9% (<jats:italic>p<\/jats:italic>\u2009=\u20090.01), respectively), lowering the odds of blood transfusion by 53% (<jats:italic>p<\/jats:italic>\u2009=\u20090.01) and shortening patients\u2019 hospital stays (11.1% reduction; <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.0001).
