This study aimed to evaluate the analgesic effects of regular postoperative duloxetine after high tibial osteotomy (HTO) and its influence on knee function, pain severity, and daily life.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This open-label randomised controlled trial was designed as a single-centre, parallel-group study. Patients undergoing HTO were randomly allocated to the control and duloxetine groups. Patients allocated to the duloxetine group were administered oral duloxetine for the first 12\u00a0weeks postoperatively and were followed up for 6\u00a0months following surgery. The primary outcome was pain assessed by the visual analogue scale (VAS), and secondary outcomes included evaluations using the Brief Pain Inventory, the Knee Society Score, and the 2011 Knee Society Score.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 38 patients in the duloxetine group and 37 patients in the control group were analyzed. The duloxetine group demonstrated significantly lower pain VAS scores at rest 6\u00a0months postoperatively compared with the control group (0.5 \u00b1 1.0 vs 1.3 \u00b1 2.0, respectively;\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      = 0.029). There were no significant differences between the groups in the other scores. However, patients in the duloxetine group showed significantly lower consumption of acetaminophen in the third postoperative week (0.0 \u00b1 0.0 vs 0.3 \u00b1 0.8 tablets\/day, respectively).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Duloxetine demonstrated a modest analgesic benefit following HTO, with reduced pain at rest at 6\u00a0months and decreased rescue medication use during the third postoperative week. Routine use after HTO may therefore not be warranted in unselected patients.
