Patients were stratified based on symptom duration into three groups: Group A (6 months to \u22641 year), Group B (1 year to &lt;2 years), and Group C (\u22652 years). The study evaluated perioperative outcomes, PROs, achievement of minimal clinically important difference (MCID) for PROs\u2014including the Visual Analog Scale (VAS), Oswestry Disability Index (ODI), and EuroQol-5D-5\u00a0L (EQ-5D-5\u00a0L)\u2014as well as satisfaction and expectation fulfillment at 6-month, 1-year, and 2-year follow-ups. Multivariable regression analyses were performed to identify predictors of poor outcomes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A cohort of 237 patients met the inclusion criteria and were stratified into three groups based on symptom duration: 66 patients with \u22641 year of symptoms, 73 patients with 1 to &lt;2 years, and 98 patients with \u22652 years. Comparative analyses revealed that patients with symptoms lasting \u22652 years had significantly longer hospital stays and higher complication rates compared to those with \u22641 year of symptoms. Additionally, this group was more likely to fail to achieve the MCID across multiple measures\u2014including the ODI, EQ-5D-5\u00a0L, VAS-Leg, and VAS-Back\u2014at the 2-years follow-up. Similar patterns were observed in satisfaction scores and expectation fulfillment rates. Multivariable regression, using the \u22641-year group as a reference, showed that patients in both the 1 to &lt;2 years and \u22652 years groups had significantly higher odds of failing to achieve MCID for VAS-Leg, VAS-Back, ODI, and EQ-5D (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; 0.05). Furthermore, both longer-duration groups were significantly less likely to report satisfaction and fulfilled expectations at all follow-up points (6-month, 1-year, and 2-years) (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; 0.05).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>A symptom duration of \u22652 years was robustly associated with inferior PROs, reduced postoperative satisfaction, and lower fulfillment of expectations.
