What is Knee injury and osteoarthritis outcome score (KOOS) – National record-based reference values about?

Background: Knee Injury and Osteoarthritis Outcome Score (KOOS) and the short form KOOS-12 are commonly used in clinical practice and research but there are no national record-based reference values to aid interpretation. The aim of this study was to establish national record-based reference values for the KOOS and its short form KOOS-12. Patients and methods: A national record-based representative sample of 9996 adult citizens were derived from the Danish Civil Registration System. The selection of citizens was based on seven predefined age groups with an equal sex distribution across each age strata. The KOOS questionnaire was sent to all participants, together with two supplemental questions regarding previous knee problems and body mass index (BMI). Results: A total of 2842 participants completed the KOOS, 1463 women (51.4%) and 1379 men (48.6%). The mean KOOS subscale scores were: pain 85.3 (95% confidence interval (CI): 84.6-85.9), symptoms 85.1 (95% CI: 84.5-85.8), activities of daily living (ADL) 86.7 (95% CI: 86.0-87.3), sport and recreation function 70.9 (95% CI: 69.8-72.0), quality of life (QOL) 74.9 (95% CI: 73.9-75.8). Age-and sex-specific reference values showed small
