Studies were included if they used the FJS\u201012 to assess patients after ACLR. The quality of included studies was appraised, and data were extracted on demographics, surgical details, and outcome measures including FJS\u201012 and its correlations with other PROMs. Descriptive statistics were used to summarize the findings.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Thirteen studies encompassing 1295 patients and 1316 knees were included. The mean age was 31.3\u2009years, and the mean follow\u2010up time was 44.3\u2009months (range of means, 12.0\u2010139.0\u2009months). FJS\u201012 scores ranged widely from 37.0 to 92.6. The score showed strong, significant positive correlations with International Knee Documentation Committee subjective knee form score, Lysholm, and Knee Osteoarthritis and Outcome Score (\n r<\/jats:italic>\n \u2009>\u20090.80 in 3 of 4 studies reporting correlations), particularly in isolated ACLR cases. FJS\u201012 showed a significant low\u2010to\u2010moderate correlation with Tegner activity levels (\n r<\/jats:italic>\n \u2009=\u20090.318\u20100.606,\n P<\/jats:italic>\n \u2009\u2264\u2009<\/jats:bold>\n .003) in 2 of 3 studies. Subgroup analyses suggested higher FJS\u201012 scores in patients with restoration of hyperextension >5\u00b0 and symmetrical range of motion to the contralateral limb. Factors such as radiographic osteoarthritis and partial meniscectomy were associated with lower FJS\u201012 scores. Across studies evaluating sex\u2010based differences, no consistent or clinically meaningful differences in FJS\u201012 scores were observed between men and women.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n The FJS\u201012 is a patient\u2010centered PROM that complements traditional metrics by capturing the subjective experience of joint awareness after ACLR. It shows moderate\u2010to\u2010strong correlations with established ACLR PROMs, supporting construct validity, and clinically meaningful thresholds have been reported, supporting clinical interpretability; however, the magnitude of responsiveness over time cannot be fully characterized because of limited reporting of longitudinal effect sizes.<\/jats:p>\n <\/jats:sec>\n \n Level of
