Long-term outcomes of anterior shoulder instability treated with open latarjet procedure - a systematic review of outcomes at a minimum 15-year follow-up.

Background: To systematically review the literature to evaluate the outcomes following an open Latarjet (OL) procedure at a minimum 15-year follow-up. Methods: Two independent reviewers performed a literature search using Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines using 3 databases. Only studies reporting outcomes of OL procedure with a minimum of 15 years of follow-up were included. Results: Nine studies composed of 326 shoulders (78.2% males) in 313 patients were included (average age 26.9 ± 3.2 years (15-58)), with a mean follow-up of 271.9 ± 69.2 months (180-420) At a minimum 15-year follow-up, 93.5% (286 of 306) patients reported being satisfied with their OL procedure, whilst 86.8% (177 of 204) reported good/excellent outcomes at final follow-up. All nine of the included studies reported an overall rate of recurrent instability was 7.7%, with re-dislocations and subluxation at 3.4% and 5.8%, respectively. The rate of surgical revision was 5.15%; 3.5% of cases were revised for recurrent instability. Instability arthropathy was reported across all included studies as 41.0%. Conclusion: The OL procedure results in satisfactory clinical outcomes, low rates of recurrent instability and surgical revision at a minimum 15-year follow-up. Although high levels of radiological instability arthropathy and residual pain are found over the same period, these appear stable from a minimum of 10-year follow-up data. Level of Evidence: IV; a systematic review of all levels of evidence.
