Bony reconstruction after failed labral repair is associated with higher recurrence rates compared to primary bony reconstruction: a systematic review and meta-analysis of 1319 shoulders in studies with a minimum of 2-year follow-up
Journal of shoulder and elbow surgery(2022)
Abstract
Background: There is uncertainty with regard to the optimal revision procedure after failed labral repair for anterior shoulder instability. An overview of outcomes of these procedures with quantitative analysis is not available in literature. The aim of this review is (1) to compare recurrence rates after revision labral repair (RLR) and revision bony reconstruction (RBR), both following failed labral repair. In addition, (2) recurrence rates after RBR following failed labral repair and primary bony reconstruction (PBR) are compared to determine if a previous failed labral repair influences the outcomes of the bony reconstruction. Methods: Randomized controlled trials and cohort studies with a minimum follow-up of 2 years and reporting recurrence rates of (1) RBR following failed labral repair and PBR and/or (2) RLR following failed labral repair and RBR following failed labral repair were identified by searching PubMed, Embase/Ovid, Cochrane Database of Systematic Reviews/ Wiley, Cochrane Central Register of Controlled Trials/Wiley, and Web of Science/Clarivate Analytics. Results: Thirteen studies met the inclusion criteria and comprised 1319 shoulders. Meta-analyses showed that RBR has a significantly higher recurrence rate than PBR (risk ratio [RR] 0.51, P <.008) but found no significant difference in the recurrence rates for RLR and RBR (RR 1.40, P <.49). Also, no significant differences were found between PBR and RBR in return to sport (RR 1.07, P <.41), revision surgery (RR 0.8, P <.44), and complications (RR 0.84, P <.53). Lastly, no significant differences between RLR and RBR for revision surgery (RR 3.33, P <.19) were found. Conclusion: The findings of this meta-analyses show that (1) RBR does not demonstrate a significant difference in recurrence rates compared with RLR and that (2) RBR has a significantly higher recurrence rate than PBR.
