Recent studies have reported a prevalence of sleep disturbance in patients undergoing arthroscopic rotator cuff repair. The purpose of our study was to explore patient-reported factors correlated with sleep disturbance in patients with arthroscopic rotator cuff repair. We retrospectively evaluated 133 patients who underwent arthroscopic rotator cuff repair for 6 months. We obtained the Pittsburgh Sleep Quality Index (PSQI) scores, the visual analog scale (VAS) pain score, the University of California-Los Angeles Shoulder Rating Scale score (UCLA score), the Hospital Anxiety and Depression Scale (HADS), and patient demographics. According to the PSQI scores, participants were divided into a sleep disorder group (A group, PSQI ≥5) and a normal sleep group (B group, PSQI <5). Statistical analyses included Student t test, Mann-Whitney U test, chi-square test, and binary logistic regression analysis to determine which patient-reported factors were associated with sleep disturbance. The mean VAS, UCLA score, UCLA Flexion, HADS-Anxiety (HADS-A), and HADS-Depression (HADS-D) scores in group A were 3.54, 26.36, 3.25, 5.43, and 5.93, respectively; in group B, the mean scores were 1.49, 30.72, 4.50, 2.11, and 1.79, respectively. There were statistically significant differences in the VAS, UCLA, UCLA Flexion, HADS-A, HADS-D scores between the 2 groups (P < .05). In the categories of sex, age, body mass index, and tear size, there was no statistical significant difference between the 2 groups. (P > .05). HADS-D and UCLA Flexion were independent factors affecting sleep disturbance after arthroscopic rotator cuff repair at 6 months (P < .05). Our study demonstrated that patients with sleep disturbances after arthroscopic shoulder surgery had a close relationship with the HADS-D, UCLA Flexion scores and had more pain, more dysfunction, and more pronounced psychological abnormalities. Therefore, more emphasis on psychotherapy and rehabilitation is required for patients with sleep disturbance.Copyright © 2024 the Author(s). Published by Wolters Kluwer Health, Inc.
