The Latarjet procedure (LP) is performed as a primary stabilization procedure (primary LP) and a salvage procedure when an earlier shoulder stabilization procedure has failed (salvage LP). However, whether primary LP or salvage LP provides better outcomes for anterior shoulder instability remains unknown. Two independent reviewers performed the literature search based on the PRISMA guidelines. A comprehensive search of PubMed, Embase, web of science and Cochrane Library was performed from their inception date to December 4, 2023. Inclusion criteria mainly included the comparison of postoperative outcomes between primary and salvage LP, English language, and full text availability. Two reviewers independently examined the literature, collected data, and evaluated the methodological robustness of the included studies. The Methodological Index for Nonrandomized Studies was used to evaluate the quality of nonrandomized studies. Recurrent instability, complications, reoperations, return to sports, patient-reported outcomes, and range of motion were assessed. Statistical evaluations were conducted using Manager V.5.4.1 (The Cochrane Collaboration, Software Update, Oxford, UK). Twelve studies were included in the systematic review, with 940 shoulders undergoing primary LP and 631 shoulders undergoing salvage LP. Statistically significant differences in favor of primary LP were found in 2 of the 11 and 2 of 4 included studies in terms of recurrent instability and returning to the same sports (RTS) at preinjury level, respectively. In terms of the visual analog scale, subjective shoulder value and the Western Ontario Shoulder Instability Index, 2 of the 4, 1 of the 3 and 1 of the 3 included studies reported statistically significant differences in favor of primary LP. Differences were not noticed regarding complications, reoperations, the time to RTS, the Rowe score, the Athletic Shoulder Outcome Scoring System, and forward flexion. Current evidence suggests that compared with primary LP, salvage LP may provide inferior postoperative outcomes in terms of recurrent instability and the rate of RTS at preinjury level. Primary and salvage LP may yield comparable efficacy in terms of complications, reoperations, the rate of RTS, the time to RTS, pain, shoulder function, and range of motion. CRD42023492027.
