Gouveia K, Abidi SK, Shamshoon S, et al. - A systematic review was conducted to analyze the rates of post-operative recurrence of instability, functional outcomes, and complications following treatment with bone augmentation procedures or arthroscopic Bankart repair with remplissage for recurrent anterior shoulder instability in the setting of subcritical glenoid bone loss. Researchers carried out to search EMBASE, PubMed, and MEDLINE from database inception until June 2019 for articles assessing either bone block augmentation to the glenoid or Bankart repair with remplissage in the setting of subcritical glenoid bone loss. They included 145 studies including four comparative studies. For recurrent anterior shoulder instability, both bone block augmentation and Bankart repair with remplissage are effective treatment options in patients with bipolar bone loss but subcritical glenoid bone loss. There was an association between arthroscopic BRR and a higher failure rate for a pre-operative glenoid bone loss greater than 10%. Thus, for cases of recurrent anterior instability, it may represent a stabilization procedure best suited with glenoid bone loss < 10% and the presence of a significant, off-track Hill-Sachs lesion.
