Background: Sleep disturbance is a major complaint of patients with rotator cuff disease that often leads them to seek treatment. The authors previously reported a prospective analysis of patients who underwent rotator cuff repair and found that sleep disturbance significantly improved at 3 months after surgery. That improvement in sleep was maintained at 6 months. Hypothesis: In the current study, the authors sought to gain medium-term data on this same population at greater than 2 years. The hypotheses were that improvement in sleep disturbance after arthroscopic rotator cuff repair is maintained at 2-year follow-up and that the continued use of narcotic pain medication has a negative effect on sleep quality at 2-year follow-up. Study Design: Case series; Level of evidence, 4. Methods: The original cohort of patients was contacted at a minimum of 24 months after their surgery. Thirty-seven of the 56 patients (66%) involved in the original study were available. Patient outcomes were scored using the Pittsburgh Sleep Quality Index (PSQI), Simple Shoulder Test (SST), visual analog scale (VAS) for pain, and Single Assessment Numeric Evaluation (SANE). The newly obtained scores were compared with prior scores, which ranged from preoperatively to 6 months postoperatively. Results: The statistically significant improvement of the PSQI score demonstrated in our prior analysis at 6 months postoperatively was maintained, with a mean PSQI score of 5.5 for the 37 patients followed beyond 24 months. Of those patients, 41% still had a PSQI score >5, indicative of sleep disturbance. However, even those patients in our study with a PSQI score >5, indicative of sleep disturbance, had an improved mean score of 9.3 at greater than 24 months compared with those patients with a PSQI score >5 at 6 months, who had a mean PSQI score of 11.5 (P = .13). Both the SST and VAS scores displayed continued improvement at greater than 24 months, with both displaying moderate strength correlation to the PSQI score (VAS: Spearman rho = 0.479, P < .001; SST: Spearman rho = −0.505, P < .001). Regression models again demonstrated the continued use of narcotic pain medication correlating with poor sleep as the difference in the mean PSQI score between users and nonusers increased as postoperative time increased. At greater than 24 months after surgery, patients using narcotics had a mean PSQI score that was 7.4 points higher than narcotic nonusers (standard error [SE] = 1.93; P = .00017). Con
