Methodological quality was assessed using the Methodological Index for Non\u2010Randomized Studies.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n A total of 9 studies were included. Reported threshold values varied substantially across patient\u2010reported outcome measures and studies. For the International Knee Documentation Committee\u2010Subjective Knee Form, minimal clinically important difference (MCID) thresholds ranged from 9.0 to 10.4, whereas patient acceptable symptom state (PASS) thresholds ranged from 74.2 to 86.8. Across the Knee Injury and Osteoarthritis Outcome Score subdomains, MCID thresholds ranged from 2.5 to 21.9, including 13.9 for pain, 5.4 for symptoms, 5.1 for activities of daily living, 2.5 for sport\/recreation, and 21.9 for quality of life. PASS thresholds for Knee Injury and Osteoarthritis Outcome Score subdomains ranged from 57.1 to 100.0, including 88.9 to 95.8 for pain, 57.1 to 94.6 for symptoms, 99.3 to 100.0 for activities of daily living, 75.0 to 82.5 for sport\/recreation, and 62.5 to 71.9 for quality of life.<\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n This systematic review of reported MCID and PASS thresholds after anterior cruciate ligament reconstruction shows considerable variability depending on patient population, method of calculation, and the nature of questions asked. This shows that previously published MCID and PASS values are not necessarily applicable in subsequent studies, and the calculation of cohort\u2010specific thresholds is important.<\/jats:p>\n
