  1. The values represent demographic data of all participants, participants with early knee osteoarthritis (EKOA), and those without EKOA. Data are presented as mean ± SD for age, BMI, and KOOS. The data of Kellgren–Lawrence (KL) grade are based on the number of participants (percentage of the whole population). The Mann–Whitney U test was used to compare the mean values of age, BMI, and KOOS scores. The Chi-square test was used to compare the proportions of KL grade between participants with and without EKOA.
  2. BMI body mass index, KOOS Knee injury and Osteoarthritis Outcome Score, KL grade Kellgren–Lawrence grade.
