We hypothesised that older age, female sex, and meniscectomy are associated with inferior PROs.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We conducted a prospective cohort study involving 733 patients (396 males and 337 females) who underwent ACLR using autologous hamstring tendons. Participants were enroled in the Hiroshima Clinical ACL Research Project. Pre\u2010operative assessments included demographic data, injury history, and scores from the five subscales of the Knee Injury and Osteoarthritis Outcome Score (KOOS). Additional assessments included the International Knee Documentation Committee (IKDC) subjective form, Lysholm score, and Tegner activity scale. Multivariable linear regression analysis was performed to identify predictors of KOOS subscale outcomes, including sex\u2010specific subgroup analyses at 1 year postoperatively.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Older age was a significant predictor of poorer KOOS outcomes across all subscales (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001). Higher body mass index (BMI) was also associated with inferior KOOS outcomes overall (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.000\u20130.012).
