Rotator cuff repair surgery is the repair of the rotator cuff. The shoulder joint consists of a small socket and a large ball and is held in place by the rotator cuff. The Swiss Atlas of Healthcare contains analyses on the frequency of surgical rotator cuff repairs in inpatient settings and in total (outpatient and inpatient). Between 2016 and 2017, and between 2018 and 2019, changes were made to the coding regulations, which must be taken into account when interpreting time series.
