However, robotic assistance and computer navigation may mitigate the volume-dependent risk of instability. This study sought to compare dislocation rates between lower-volume surgeons performing technology-assisted (TA) THAs and higher-volume surgeons utilizing conventional instrumentation (CI).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>The Premier Healthcare Database was queried to identify adult patients who underwent primary elective THA from 2016 to 2023. Surgeons with &lt;10% technology use formed the CI group, and surgeons with \u226590% technology use formed the TA group. These groups were further subdivided into higher-volume (HV) and lower-volume (LV) on the basis of surgeon annual case-volume, using a previously validated threshold of 109 cases\/year. Mixed-effects modeling was used to compare the 90-day risk of dislocation between patients treated by low-volume surgeons using TA (LV-TA group) and high-volume surgeons using CI (HV-CI group).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>A total of 669,098 patients undergoing THA were identified. Of these, 5,447 patients were treated by LV-TA surgeons and 190,550, by HV-CI surgeons. Notably, LV-TA surgeons achieved a similar rate of dislocation compared with HV-CI surgeons (0.48% versus 0.42%, p = 0.510). After controlling for confounding factors, the risk of dislocation remained comparable between LV-TA and HV-CI surgeons (adjusted odds ratio: 1.062, 95% confidence interval: 0.677 to 1.668, p = 0.793).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>Surgeons with a lower case-volume who used technology assistance achieved a rate of dislocation similar to that of surgeons with a higher case-volume who used conventional instrumentation. These findings demonstrate that technology assistance, including computer navigation and robotic assistance, may attenuate the association between surgeon case-volume and dislocation risk following primary THA.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Level of Evidence:<\/jats:title>\n                    <jats:p>\n                      Therapeutic\n                      <jats:underline>Level III<\/jats:underline>\n                      .
