Dual-energy X-ray absorptiometry (DXA) is the standard diagnostic tool; however, many patients remain unscreened. Preoperative computed tomography (CT) scans obtained for robotic-assisted total knee arthroplasty (TKA) planning present an opportunity for opportunistic osteoporosis screening without additional radiation exposure.\n                    <jats:italic>Methods<\/jats:italic>\n                    : A retrospective observational study was conducted on 637 patients (307 males, 330 females) who underwent robotic-assisted TKA between January 2023 and December 2024. Preoperative CT scans were analyzed using quantitative computed tomography (QCT) software to determine\n                    <jats:italic>T<\/jats:italic>\n                    -scores,\n                    <jats:italic>Z<\/jats:italic>\n                    -scores, and percentage of bone mineral density (BMD) relative to a young-adult reference.

Notably, 37.0% of female patients were osteoporotic compared to 15.3% of male patients. Bone density parameters declined progressively with age, with females over 80 years exhibiting a mean\n                    <jats:italic>T<\/jats:italic>\n                    -score of \u22122.53 and BMD at 68.25% of the young-adult reference.\n                    <jats:italic>Discussion<\/jats:italic>\n                    : Opportunistic screening using preoperative CT scans in robotic-assisted TKA patients reveals a high prevalence of undiagnosed low BMD, particularly among elderly women. Integrating QCT analysis into the preoperative workflow may facilitate early identification of at-risk individuals, informing surgical planning and enabling timely interventions to improve bone
