Preoperative and follow\u2010up (FU) scores in each\u00a0Scoliosis Research Society\u201022\u00a0(SRS\u201022)\u00a0domain were compared with age\u2010 and sex\u2010matched normative references. At baseline, patients were classified by differences from normative values in four groups: Worst, Severe, Poor, and Moderate. At 2 years postoperative FU, patients were divided into four groups (Worst\u00a0Severe Poor Asymptomatic) based on the difference in MCID between postoperative and normal values. The changes in MCID were considered as the criterion for surgical efficacy. In addition, we calculated the classification of preoperative and FU clinical symptom severity in each domain in same patient. The distinction among curve types was also performed based on the SRS\u2010Schwab classification. A total of 123 patients were included. During FU, patients with more severe preoperative clinical symptoms were more likely to achieve clinical changes (&gt;1 MCID, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05), but the rate of reaching \u201casymptomatic\u201d was lower (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05). Kendall's tau\u2010b correlation analysis found that preoperative clinical severity was correlated with clinical changes category in Activity (Tau\u2010b\u2009=\u20090.252; <jats:italic>p<\/jats:italic>\u2009=\u20090.002), Pain (Tau\u2010b\u2009=\u20090.230; <jats:italic>p<\/jats:italic>\u2009=\u20090.005), Appearance (Tau\u2010b\u2009=\u20090.307; <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001), and Mental (Tau\u2010b\u2009=\u20090.199; <jats:italic>p<\/jats:italic>\u2009=\u20090.016), and it also was correlated with FU clinical severity in Activity (Tau\u2010b\u2009=\u20090.173; <jats:italic>p<\/jats:italic>\u2009=\u20090.023), Pain (Tau\u2010b\u2009=\u20090.280; <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001), and Mental (Tau\u2010b\u2009=\u20090.349; <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001). There was a correlation between preoperative clinical severity and FU\u00a0SRS\u201022 score outcomes. Patients with severe preoperative clinical symptoms can experience better treatment outcomes during FU, but it is also more difficult to recover to the normal
