Sex-specific differences in outcomes after anterior shoulder surgical stabilization: a meta-analysis and systematic review of literature

Ezra Goodrich et al. JSES Int. .

Abstract

Background: Anterior shoulder instability frequently occurs in young, physically active individuals and may be treated with surgical stabilization. Previous studies have shown that males more often require surgical management for anterior shoulder instability and may have a higher frequency of recurrent instability episodes after surgical management, but females have been found to have increased incidence of apprehension after surgical stabilization. The purpose of this study is to review the literature and assess anterior shoulder surgical stabilization postoperative outcomes between males and females to identify and describe sex-based differences.

Methods: A systematic search of electronic databases was conducted to identify level I-IV clinical studies on anterior shoulder instability published between 1960 and August 2020. We included studies that evaluated sex-specific outcomes in patients who underwent anterior shoulder instability procedures. A meta-analysis of the data was performed to analyze sex-specific outcomes.

Results: Thirty studies (2.1%) met inclusion criteria, representing 9829 patients. Of the studies that reported the number of male and female patients, 74% were male and 26% were female. Twenty-six studies used Bankart repair alone, two used open Latarjet procedure alone, and two had a Bankart repair group and Latarjet procedure group. Instability recurrence, return to sport, and apprehension were included in the meta-analysis. Our meta-analysis demonstrated a significantly higher rate of instability recurrence for males than for females who underwent arthroscopic Bankart repair (risk ratio [RR] = 1.25; 95% confidence interval [CI] = 1.03, 1.52; P = .0239). We did not identify a significant difference between males and females in rates of apprehension (RR = 0.68; 95% CI = 0.37, 1.27; P = .2300) or return to sport (RR = 0.98; 95% CI = 0.81, 1.18; I2 = 0%; P = .8110) for arthroscopic Bankart repair or open Latarjet procedure.

Conclusion: For patients who underwent arthroscopic Bankart repair for anterior shoulder stabilization, recurrent rates of instability were significantly higher for males than for females. When open Bankart and Latarjet procedures were included, there was no difference. No difference was seen between males and females after arthroscopic Bankart repair or open Latarjet procedures with regard to return to sport or apprehension.
