title: Redislocation risk after an arthroscopic Bankart procedure in collision athletes: a systematic review.
abstract: BACKGROUND
  The purpose of this review was to determine the redislocation risk for collision athletes after an arthroscopic Bankart repair and to compare the redislocation rate between collision athletes and noncollision athletes after an arthroscopic Bankart repair.
  
  
  METHODS
  A PubMed and Embase query was performed, screening all relevant literature of arthroscopic Bankart procedures mentioning redislocation rates in collision athletes. Studies with a follow-up <2 years or lacking information on redislocation rates in collision athletes were excluded. We used the modified Coleman Methodology Score to assess the quality of included studies. Finally, the data in all the studies were combined and analyzed.
  
  
  RESULTS
  There were 1012 studies screened on title and abstract, of which 111 studies were full-text screened, and finally 20 studies were included. Four studies reported on collision athletes only, whereas 16 compared collision with noncollision athletes. Fourteen studies reported increased redislocation rates for collision athletes in comparison to noncollision athletes (absolute risk difference varying from 0.4% to 28.6%), whereas 2 studies reported decreased rates (absolute risk differences of -6% and -2.4%). A combined analysis revealed that collision athletes have an increased absolute risk of 8.09 with 95% CI from 3.61 to 12.57% for development of postoperative instability in comparison to noncollision athletes (P = .001).
  
  
  CONCLUSIONS
  Collision athletes have an increased risk for redislocation in comparison to noncollision athletes after an arthroscopic Bankart repair, although there were no differences in return to sport.
