Following publication of this article [1], the authors report the following Corrections to the main text:

  1. i)

    The authors were made aware, that in the cohort of Kukkonen et al. [2, 3] the surgical group was labelled as conservative, and the conservative group as surgical. In view of this error, the authors corrected the database and performed the statistical analysis again (revised Table 3). The results were modified accordingly (revised Fig. 2, revised Fig. 3).

  2. ii)

    The authors found that the main conclusion is unchanged, namely that there is no significant difference in terms of Constant and Murley score (CMS) between surgical and conservative treatment in patients with rotator cuff tears at two-year follow-up.

  3. iii)

    Results showed statistically significant differences between the CMS measured at one year of follow-up, a secondary outcome, in favour of surgical rotator cuff repair compared with patients treated conservatively (P = 0.003).
