Outcomes of Revision Surgery for a Failed Prior Latarjet Procedure A Systematic Review

This study systematically reviewed the literature for outcomes following revision surgery for a failed prior Latarjet procedure.Two independent reviewers performed the literature search based on PRISMA guidelines using the EMBASE, MEDLINE, and The Cochrane Library databases. Studies in which the Latarjet procedure was performed as a revision procedure following failed prior shoulder instability surgery were included. Clinical outcomes analyzed were: 1. functional outcomes, 2. recurrent instability, 3. range of motion, and 4.Statistical analysis was performed using IBM SPSS.There were seven studies with 161 patients (162 shoulders) included. Four studies used a bone-block procedure, three used arthroscopic soft-tissue stabilization, and the mean follow-up was 49.8 months. The most commonly reported functional outcome measure was the Rowe score, with a weighted mean average of 79.7, with 82.9% of patients having good to excellent outcomes. Return to play was possible for 73.8% of patients, with 64.2% of those returning to at least the same level of competition. The overall recurrence rate was 9.5%, with 3.6% and 5.9% experiencing recurrent dislocations and subluxations, respectively. The overall revision rate was 4.2%, with all patients undergoing revisions due to recurrence. There were no reported neurovascular complications. Instability arthropathy was reported in 43.3% of patients.Surgical management following a failed Latarjet procedure results in moderate rates of recurrent instability and has a low intraoperative and postoperative complication rate. Additionally, the results across all techniques appear similar, with no procedure being identified as the gold-standard in the literature. However, there was a concerning rate of instability arthropathy, which may be related to the failure of a bony procedure.
