Are collision athletes at a higher risk of re-dislocation after an open Bristow-Latarjet procedure? A systematic review and meta-analysis

Background: The primary aim of the present study was to review, summarize and compare the redislocation risk for collision athletes and noncollision athletes after an open Bristow-Latarjet procedure. Our secondary aim was to summarize return to sport, satisfaction, pain and complications. Methods: We conducted a systematic review in PubMed and EMBASE of articles until 1 July 2016. We included all studies describing Bristow-Latarjet like procedures as a result of glenohumeral instability, mentioning redislocation rates in collision athletes with >2 years of follow-up. We pooled the data using random-effects meta-analysis for redislocation risk-differences (RD) between collision and noncollision athletes, and assessed heterogeneity with I2 and Tau2 tests. Results: From 475 titles and abstracts, 11 studies were included and eight studies were meta-analyzed. The pooled RD to develop a postoperative redislocation between collision athletes and noncollision athletes was -0.00 (95% confidence interval: -0.03 to 0.03, p = 0.370). Return to sports rates were high (67-100%), and patients reported high satisfaction scores (93-100% satisfied) and low pain scores (mean visual analogue scale score of 1.6); however, postoperative complication rates varied from 0.8% to 19.2%. Conclusions: Collision athletes are not more at risk for redislocation rates after an open Bristow-Latarjet procedure compared to noncollision athletes. Overall postoperative outcomes were good, although numerous complications occurred.
