As value-based care initiatives prioritize PROMs such as pain relief, functional recovery, and satisfaction, understanding age-specific differences is critical.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We analyzed 1772 patients who underwent unilateral, fully cementless primary TKA between 2016 and 2023 using a prospectively collected institutional registry. Patients were stratified by age (\u2264\u200960, 60\u201370,\u2009&gt;\u200970\u00a0years), and outcomes included KOOS subscales (Pain, Physical Function Shortform [PS], and Joint Replacement [JR]), minimal clinically important difference (MCID), Patient Acceptable Symptom State (PASS), and satisfaction at 1\u00a0year. Multivariable logistic regression adjusted for baseline PROMs and demographic covariates.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Older patients (&gt;\u200970) had significantly higher baseline KOOS scores and were more likely to exhibit favorable PROM phenotypes compared to younger cohorts. At 1\u00a0year, all groups experienced substantial improvement, with the\u2009&gt;\u200970 group achieving the highest absolute KOOS scores. Patients aged 60\u201370 had significantly lower odds of failing to meet MCID (KOOS JR: OR 0.58; p\u2009=\u20090.027) and PASS thresholds (KOOS Pain: OR 0.75; KOOS PS: OR 0.75) compared to those\u2009\u2264\u200960. Older adults demonstrated non-inferior performance across all metrics, including satisfaction, which exceeded 83% across all age groups (p\u2009=\u20090.88).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Cementless TKA yields strong MCID and PASS threshold achievement and high satisfaction across all age groups.
