The influence of psychosocial factors on patient-reported outcome measures in rotator cuff tears pre- and post-surgery: a systematic review

Recent research shows that major levels of psychological distress correlate with higher pain and reduced function in patients with shoulder and rotator cuff pathology. A systematic review updating a review published in 2016 was conducted to determine the degree of consistency and the strength of association between psychosocial factors and patient-reported outcomes (PROMs) in patients with rotator cuff repair (RCR) with new high-quality literature.

The bibliographic searches were conducted from May to June 2020 within the following databases: MEDLINE/PubMed, EMBASE, Cumulative Index to Nursing and Allied Health Literature (CINAHL), PsycINFO, and Web of Science. The articles included should discuss the association between psychosocial factors and outcomes in patients with documented or diagnosed rotator cuff tears through clinical and/or radiological examination. The Methodological Index for Non-Randomized Studies (MINORS) tool was used to assess the methodological quality.

Fifteen articles were included. Negative psychosocial factors were found consistently associated with worse function and disability in the pre- and post-operative period. In particular, psychosocial factors regarding emotional or mental health were associated with a weak to a substantial degree with preoperative and postoperative function/disability and pain intensity in patients undergoing RCR.

In patients undergoing repair of the rotator cuff tear, there was a correlation between poor psychological function before surgery and worsening post-surgical outcomes, such as persistence of postoperative pain intensity and worse levels of function/disability.
