At 6\u00a0months postoperatively, patients graded their knee function based on a domain\u2010specific anchor question. A satisfaction anchor question was used to indicate achievement of the PASS. Receiver operating characteristic analysis determined the relevant psychometric values. Cutoff analysis was performed to find preoperative patient\u2010reported outcome scores predicting achievement of clinically significant outcomes (CSOs).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>A total of 73 patients (41.1% female patients) were included, with a mean age of 44.9 \u00b1 12.8.0\u00a0years and average follow\u2010up period of 24.0 \u00b1 1.2\u00a0weeks. The MCID on the PROMIS PF CAT was calculated to be 2.09 (area under the curve [AUC], 0.75; 95% CI, 0.57\u20100.94). Net score improvement equivalent to achievement of SCB was found to be 6.50 (AUC, 0.77; 95% CI, 0.55\u20100.99). The PASS was found to be 46.1 (AUC, 0.86; 95% CI, 0.76\u20100.96). A preoperative score below 37.6 on the PROMIS PF CAT predicted achievement of the MCID (AUC, 0.76; 95% CI, 0.62\u20100.87), whereas scores above 41.9 predicted achievement of the PASS (AUC, 0.77; 95% CI, 0.65\u20100.90). Higher baseline functional status and the absence of pre\u2010existing arthritis were also found to be statistically significant predictors of achieving CSOs.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Our study defined the MCID, SCB, and PASS for the PROMIS PF CAT. We found that a preoperative score below 37.6 was predictive of achieving a meaningful clinical change with surgery whereas a preoperative score above 41.9 was predictive of patients who would attain an acceptable postoperative health state. In addition, exercising more days per week and the absence of arthritis increased the likelihood of achieving postoperative CSOs.<\/jats:p>\n                  <\/jats:sec>\n
