A previous study had established the normative scores of a population in the USA but\u00a0included knees with pathology. The aim of our study is to obtain normative Forgotten Joint Scores in young Asian adults without any pre-existing knee pathologies to increase the interpretability of the Forgotten Joint Score-12 (FJS-12) score.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>We conducted a cross-sectional study across young healthy Asian adults via electronic platforms. Participants who had sought either Western medical consultation, physiotherapy or traditional medical therapies were excluded. Demographic data, occupation, type of sport played, and FJS-12 scores were collected. Scores were stratified into subgroups and analysed.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>There were 172 participants who met our inclusion criteria for this study. The average age of participants in our study was 28.1\u2009\u00b1\u200910.5\u00a0years (range 14\u201370\u00a0years), with 83 (47.7%) participants falling into the ages 21\u201325\u00a0years. Average body mass index (BMI) was 21.9\u2009\u00b1\u20093.3\u00a0kg\/m<jats:sup>2<\/jats:sup> (range 14.7\u201336.3\u00a0kg\/m<jats:sup>2<\/jats:sup>). The average FJS-12 score was 62.8\u2009\u00b1\u200925.6. The median FJS-12 was 63.5 with a range of 4.2\u2013100. Nine participants (5.2%) scored the maximum score possible, and 56 (32.6%) participants scored below the midpoint score of 50. The percentiles for each subgroup of participants were tabulated and reported. Notably, males aged 46\u201370\u00a0years old scored the highest average FJS-12 score of 73.4\u2009\u00b1\u20095.5, and females aged 31\u201345\u00a0years old scored the lowest FJS-12 score of 57.1\u2009\u00b1\u200925.1. Females scored lower than males, although the difference was not statistically significant (<jats:italic>p<\/jats:italic>\u2009=\u20090.157). There were no significant correlations between BMI, age, or type of sport played with FJS-12; however,\u00a0interestingly, we observed that women reported similar FJS-12 scores across all age groups, while men reported better scores with increasing age.Interestingly,\nwe observed that women reported similar FJS-12 scores across all age groups,\nwhile men reported better scores with increasing age.\u00a0<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>Having normative values provides opportunities for benchmarking and comparing individuals against age- and gender-matched peers in the general population.
