This paper demonstrates the feasibility and reproducibility of the first all arthroscopic procedure to combining a glenoid bone graft augmentation according to Taverna (Taverna et al., 2014) and a partial subscapularis tenodesis according to Maiotti (Maiotti & Massoni, 2013) to treat recurrent complex anterior instability associated with glenoid bone loss of about 25% and capsular inconsistency. The optimal treatment of this pathology, especially if associated with a glenoid bone defect, has not yet been entirely established (Symeonides, 1989; An et al., 2016; Kempf et al., 1999; Morrey & Janes, 1976; Rowe et al., 1978; Wymenga & Morshuis, 1988). The open trans-glenoid Bankart reinsertion was considered for years the “gold standard” for treating recurrent instability and has given excellent results, with a recurrence rate of 1%. However, broad use of this technique, arthroscopically assisted using anchors and popularized as the Bankart repair, remains more controversial because of the relatively high number of recurrences of 20% to 64%, especially if associated with glenoid bone defects (Alkaduhimi et al., 2016; Burkhart & De Beer, 2000; Cole & Warner, 2000; Field et al., 1999; Morrey & Janes, 1976; Bankart, 1938). This clinical survey was supported by the biomechanical and clinical retrospective studies (Arciero et al., 2015; Longo et al., 2014).
