The aim of this systematic review was to summarize the clinical outcomes and associated predictors of outcomes for chronic glenohumeral dislocations treated with arthroplasty.

A systematic literature search was performed with Embase, PubMed, CENTRAL, BIOSIS, and CINAHL databases from the inception of these databases through January 1, 2021 to identify all articles that examined outcomes or predictors of outcomes of arthroplasty in patients with chronic glenohumeral dislocations.

Studies that examined outcomes for patients with a chronic glenohumeral dislocation (≥3 weeks) treated with hemiarthroplasty, anatomic total shoulder arthroplasty, or reverse total shoulder arthroplasty were included.

Those with acute or subacute dislocations (<3 weeks), fracture dislocations, and those treated with joint preserving treatment modalities were excluded.
