The purpose of this study was to confirm predictors for the forgotten joint in TKA patients.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This was an observational, prospective longitudinal study. A total of 205 patients who underwent TKA and a 6\u2010month follow\u2010up were included between August 2020 and September 2021. Demographic characteristics, clinical characteristics, and psychosocial variables were collected before TKA surgery (T0). The forgotten joint score (FJS) was taken before TKA surgery (T0) and at 1\u2009month (T1), 3\u2009months (T3), and 6\u2009months (T6) after TKA surgery. The psychosocial variables were also completed at T6. Bivariate and multivariable linear regressions (LR) were performed to screen the predictors associated with FJS (T6).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Patients who underwent TKA in our study had a mean FJS of 20.3\u2009\u00b1\u200912.2 before surgery, 15.9\u2009\u00b1\u200910.3 at 1\u2009month, 28.7\u2009\u00b1\u200912.6 at 3\u2009months, and 40.3\u2009\u00b1\u200912.5 at 6\u2009months. The predictors were sex, combined musculoskeletal disorders (MSD), operation time, FJS (T3), range of motion (ROM) (T6), pain score (T6), Groningen orthopaedic social support scale (GO\u2010SSS) score (T6), and the generalized anxiety disorder scale (GAD) score (T6). The data satisfied the assumptions of multivariable linear regressions. The multiple <jats:italic>R<\/jats:italic><jats:sup>2<\/jats:sup>of LR was 0.71, and the adjusted <jats:italic>R<\/jats:italic><jats:sup>2<\/jats:sup> was 0.70. The <jats:italic>F<\/jats:italic>\u2010statistic of the LR model was 59.5 (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.000).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Our study revealed the level of forgotten knee decreased slightly from preoperation to 1\u2009month postoperatively and then increased from 1\u2009month postoperatively to 6\u2009months postoperatively in TKA patients. The main predictors associated with the FJS at 6\u2009months after surgery were sex, combined MSD, operation time, FJS (T3), ROM (T6), pain score (T6), GO\u2010SSS score (T6), and anxiety
