Lower limb apophysitis cause long-term pain, decrease in function, and can reduce or completely hinder participation in sports and physical activity, yet there is little knowledge on the long-term consequences for health. Our objective with this investigation is to capture self-reported health-status for all adults having been diagnosed with lower limb apophysitis in the period of 1977 to 2020 and compared these data with normative values for the background population. We are therefore conducting a national cross-sectional study based on data from the Danish National Patient Registry. In this protocol we describe, as detailed as possible, the planned methods.
