Method The KOOS or KOOS-Child (each containing five subscales) was administered to participants aged 8–101 years within the 1000 Norms Project, an observational study of 1000 self-reported healthy individuals. Self-efficacy, physical activity, body mass index (BMI), lower limb alignment, knee frontal plane projection angle (FPPA), knee range of motion (ROM), knee and hip strength, six-minute walk, 30-second chair stand and timed up and down stairs tests were collected. KOOS data were dichotomised using established cut-off scores and logistic regression analyses were conducted for each subscale. Results Socio-demographic characteristics were similar to the Australian population. Normative reference data were generated for children (8–17 years) and adults (18–101 years). Female adults were up to twice as likely to report knee pain, symptoms and sport/recreation (Sport/Rec) limitations compared to males (P}, doi = {10.1016/j.joca.2017.03.007}, eissn = {1522-9653}, issn = {1063-4584}, issue = {8}, journal = {Osteoarthritis and Cartilage}, pages = {1282-1290}, publicationstatus = {Published}, publisher = {Elsevier}, url = {https://hull-repository.worktribe.com/output/3635232}, volume = {25}, keyword = {Knee, Self-report, Surveys and questionnaires, Disability evaluation, Physical fitness}, year = {2017}, author = {Baldwin, J.
