Improvements in Sleep After Shoulder Arthroscopy Are Correlated With Improvements in Various Patient-Reported Outcomes: A Systematic Review

Abstract

Purpose

To determine the prevalence of sleep disturbances in patients before and after arthroscopic surgery of the shoulder and to evaluate the association between patient-reported outcomes and standardized sleep disturbance tools after shoulder arthroscopy.

Methods

A systematic review, following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines, was conducted by searching the PubMed, Embase, and Scopus databases using the terms “arthroscopic surgery” and “sleep.” Two independent reviewers evaluated the studies based on the inclusion criteria focused on the effects of shoulder arthroscopy on sleep disturbance and the use of outcome measures related to sleep. Data on sleep quality and functional outcomes were collected and analyzed using various assessment tools, including the Pittsburgh Sleep Quality Index and American Shoulder and Elbow Surgeons score. The methodologic quality of included studies was assessed using the Methodological Index for Non-randomized Studies (MINORS) criteria.

Results

The review included 15 studies (9 Level IV, 5 Level III, and 1 Level II) comprising 1,818 arthroscopic patients (average age, 57.4 ± 8.86 years; follow-up range, 6 months to 75.7 months). The prevalence rates of sleep disturbances before and after shoulder arthroscopy ranged from 75.8% to 100% and from 19% to 62%, respectively. Every study included in this analysis reported an improvement in rates of sleep disturbances postoperatively compared with preoperatively. Improvements in standardized sleep disturbance scores were associated with functional outcomes.

Conclusions

Sleep disturbances are commonly observed before and after arthroscopic surgery of the shoulder. Arthroscopic surgery of the shoulder appears to improve sleep quality, and surgeons can expect functional outcomes, specifically the American Shoulder and Elbow Surgeons score, Simple Shoulder Test score, numeric rating scale or visual analog scale score, and Constant-Murley score, to improve in line with sleep quality.

Level of Evidence

Level IV, systematic review of Level II to IV studies.
