The survival estimates for doctor-diagnosed knee OA among persons aged 16–45 years in patients having had APM, meniscal repair or in the general population. The start of follow-up is the date of surgery for the APM and meniscal repair groups, and the date of first healthcare contact with a physician after January 1st 1998 for the general population. Shaded areas indicate 95% CIs.

Prevalence and strength of an unmeasured confounder (U) (for example bias by indication) needed to explain our results, if there was truly no difference in the incidence of knee OA between the APM and meniscal repair group. observed HR – hazard ratio observed in our study, true HR – assumed true hazard ratio. HRs needed to explain our observed estimates of 0.5 with the prevalence of U two times higher in APM than meniscal repair group were between 50 and 500 and this not presented in the figure.
