Open Versus Arthroscopic Latarjet Procedure for Anterior Shoulder Instability: A Systematic Review and Meta-analysis

Abstract

Background: Anterior shoulder instability with significant glenoid bone loss is a challenging condition. The open Latarjet procedure is the established standard treatment method in this setting, but there is an increasing use of the arthroscopic technique. Purpose: To systematically review the current evidence in the literature to ascertain if the open or arthroscopic Latarjet procedure resulted in improved patient outcomes. Study Design: Systematic review and meta-analysis. Methods: A literature search of MEDLINE, EMBASE, and the Cochrane Library was performed based on the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines. Cohort studies comparing the open and arthroscopic Latarjet procedures for anterior shoulder instability were included. Clinical outcomes were compared, with all statistical analysis performed using Review Manager (version 5.3). A P value of <.05 was considered statistically significant. Results: Six clinical trials with 896 patients were included. The open and arthroscopic Latarjet procedures resulted in a similar number of total recurrent instability (2.0% vs 2.4%; P = .75), revision procedures (2.4% vs 5.4%; P = .06), and total complications (13.8% vs 11.9%; P = .50), but the open procedure had a lower rate of persistent apprehension (10.2% vs 35.7%; P < .05). In addition, after the learning curve, the operative time was similar between the 2 procedures. Conclusion: Both the open and arthroscopic Latarjet procedures result in significant improvements in patient function and outcome scores, with low rates of recurrent instability and similar complication rates. While technically challenging, the arthroscopic procedure has been shown to be a safe and viable alternative. However, there is a significant learning curve associated with the arthroscopic Latarjet procedure. The significant learning curve associated with this procedure suggests the arthroscopic procedure may be advisable to perform only in high-volume centers with experienced arthroscopists.
