Considering the recent positive experience using partial subscapularis tenodesis on the glenoid rim, known as arthroscopic subscapularis augmentation (Maiotti & Massoni, 2013; Maiotti et al., 2017; Maiotti et al., 2016; Schröter et al., 2016) (ASA), to treat recurrent anterior instability with capsular inconsistence and moderate glenoid bone loss (GBL), we decided to apply both techniques - ASA and Bone Block (ASA-BB) - in very complex cases in which a glenoid bone defect equal to or greater than 25% is associated with capsular insufficiency. ASA procedure solve the problem of an hyperlax capsule or insufficient tissues, instead of treating it with a simple anterior capsulorraphy. The aim of this cadaver study was to demonstrate the feasibility and reproducibility of the combination of these two techniques in the treatment of severe glenoid bone loss (GBL) associated with anterior capsular insufficiency. Our hypothesis was that these two procedures could be combined arthroscopically.
