^*Frequent knee symptoms were defined as knee pain, aching, or stiffness in the right knee on most days. Radiographic evidence of osteoarthritis was considered present if the Kellgren–Lawrence grade was 2 or higher. Data for 49 of the 991 subjects in the community-based sample were not available (because of missing radiographs, responses to the item in the questionnaire regarding frequent knee symptoms, or both).

^†The prevalence ratios were calculated as the proportion of subjects with meniscal tears among those with frequent knee symptoms divided by the corresponding proportion among subjects without frequent knee symptoms.

^‡The prevalence ratio is adjusted for age, sex, and body-mass index.
