Objectives This study aims to investigate the relationship between preoperative sleep disturbance and postoperative pain in patients with a rotator cuff tear, and to provide a theoretical basis for taking corresponding interventions to alleviate postoperative pain in patients with rotator cuff tear. Methods A total of 87 patients, who had undergone shoulder arthroscopy due to rotator cuff injury in Hunan Provincial People‘s Hospital from January to October 2021, were selected as the research subjects. The Pittsburgh Sleep Quality Index (PSQI) was used to evaluate the sleep quality of patients with rotator cuff tears. All patients were divided into the low sleep quality group (PSQI score >7 points, n = 61) and the high sleep quality group (PSQI score ≤7 points, n = 26). Postoperative pain was assessed by using the Numerical Rating Scale (NRS). General clinical data of the patients were collected 1 day, 2 days, and 1 month after surgery. Univariate and multivariate analyses of influencing factors were performed in patients with moderate or above pain at 1 month after surgery. Results The score of postoperative pain of patients in the high sleep quality group was significantly lower than that of patients in the low sleep quality group (P < 0.05). A total of 35 patients (40.2%) had moderate or above pain 1 month after surgery, including 5 patients (19.2%) in the high sleep quality group and 30 patients (49.2%) in the low sleep quality group. The incidence rate of the low sleep quality group was significantly higher than that of the high sleep quality group (P = 0.009). After controlling confounding factors, preoperative sleep disturbance of patients was still independently associated with the occurrence of moderate or above pain 1 month after surgery (OR = 3.794, 95% CI: 1.261–11.409, P = 0.018). Conclusion Preoperative sleep disturbance can increase the risk of postoperatively moderate or above pain threshold in patients with rotator cuff tear. Paying more attention to and actively improving preoperative sleep disturbance can effectively promote postoperative pain management in patients with rotator cuff tears.
