aAnnual incidence rates calculated as number of meniscal procedures performed per 100,000 Dutch inhabitants, from 2005 to 2014 the incidence of meniscus surgeries decreased (p < 0.001), and the incidences were lower after the introduction of the national guideline compared to before its implementation (p < 0.001)
bGender specific incidence numbers, per 100,000 male/females, the incidence of meniscus surgeries was higher for men than for women (p < 0.001)
cAge corrected incidence numbers, per 100,000 Dutch inhabitants per age cohort, the incidence of meniscus surgeries was highest in persons aged 65–80 years (p < 0.001) compared to other age groups
