Participants were allocated by admission date: the intervention group (March\u2013April, [Formula: see text] 35) received enhanced recovery protocols with standard pain management, while the control group (May\u2013June, [Formula: see text] 35) received standard management alone. Pain outcomes were assessed at postoperative weeks 2 (T1), 1 month (T2), and 3 months (T3) using validated tools: Pain Catastrophizing Scale (PCS), Numerical Rating Scale (NRS), and APS-POQ-C (Chinese version) to evaluate catastrophisation, intensity, and management efficacy. Generalized Estimating Equations (GEEs) were employed for longitudinal statistical analysis.<\/jats:p>\n                  <jats:p>Results: The ER program showed statistically significant main effects across groups ([Formula: see text]), temporal effects (P \u0393 0.001), and group-time interaction effects ([Formula: see text]) on pain catastrophisation scores, pain intensity scores, and pain management outcomes, respectively. And as time went on, the intervention group showed greater improvement than the control group in pain catastrophizing (PCS:T1[Formula: see text]16,T2[Formula: see text]9,T3[Formula: see text]5 versus T1[Formula: see text]29,T2[Formula: see text]23,T3[Formula: see text]19.5), pain intensity (Pain: T1[Formula: see text]4,T2[Formula: see text]2.5,T3[Formula: see text]1 versus T1[Formula: see text]4,T2[Formula: see text]3,T3[Formula: see text]2) and pain management outcomes (APS-POQ-C: T1[Formula: see text]12.125,T2[Formula: see text]3.875,T3[Formula: see text]1.25 versus T1[Formula: see text]15.75,T2[Formula: see text]9.5,T3[Formula: see text]5).<\/jats:p>\n                  <jats:p>Conclusions: The ER program significantly reduced postoperative pain intensity and catastrophisation in TKA patients, enhancing pain management outcomes compared to conventional therapies. Its concentrated 2 h format demonstrates promising efficacy over standard care, offering a streamlined alternative to traditional postoperative regimens.<\/jats:p>","DOI":"10.1142\/s1013702526500125","type":"journal-article","created":{"date-parts":[[2026,6,30]],"date-time":"2026-06-30T17:23:03Z","timestamp":1782840183000},"page":"157-174","source":"Crossref","is-referenced-by-count":0,"title":["Effects of empowered relief on pain catastrophizing and outcomes post-total knee arthroplasty: A quasi-experimental study"],"prefix":"10.1142","volume":"46","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-2074-1199","authenticated-orcid":false,"given":"Qiongfang","family":"Cui","sequence":"first","affiliation":[{"name":"Nursing Department, The Second Hospital of Lanzhou University, Lanzhou 730030, P.
