Abstract
Arthroscopic management of post-traumatic anterior gleno-humeral micro-instability, in the non-athletes, hasn't yet been thoroughly investigated. The current study compared outcomes of antero-inferior capsulo-labral repair for management of anterior gleno-humeral micro-instability (following single-event trauma in the non-athletes) versus those of Bankart repair for management of recurrent anterior gleno-humeral dislocation/macro-instability. Conducted between March 2018 and February 2024, this case-control study included 62 patients allocated according to the managed pathology into 2 groups. Group-(A) included 21 non-athletes with anterior gleno-humeral micro-instability (following single-event trauma) managed with suture-anchor antero-inferior capsulo-labral repair coupled with intra-articular soft arthroscopic Latarjet technique (in-SALT) including soft-tissue biceps tenodesis to upper subscapularis. Whereas group-(B) included 41 non-athletes with recurrent anterior gleno-humeral dislocation/macro-instability (i.e., type-V superior labrum anterior to posterior [SLAP] lesion) managed with suture-anchor Bankart repair coupled with in-SALT. Outcome measurements included 2-year postoperative Visual Analogue Scale (VAS) score; range of forward flexion (FF) and external rotation (ER) at 90<sup>O</sup>-abduction; and the American Shoulder and Elbow Surgeons (ASES) and Rowe scores. There were no inter-group statistically-significant differences in baseline patient characteristics. Mean age of the patients was (26.8 ± 7.0) in group-(A); and (26.6 ± 6.8) in group-(B). Other than 1 female patient in each group, all included patients were male. Except for range of motion in group-(A), patients in both groups had significant postoperative improvement in all outcome measurements (P < .05 for all). Both groups showed comparable postoperative outcomes in terms of VAS score (1.0 ± 0.8 vs 1.1 ± 0.9; P = 0.607), FF (173.8<sup>O</sup> ± 7.4<sup>O</sup> vs 172.2<sup>O</sup> ± 5.2<sup>O</sup>; P = 0.324), ER at 90<sup>O</sup>-abduction (83.3<sup>O</sup> ± 7.3<sup>O</sup> vs 80.7<sup>O</sup> ± 6.1<sup>O</sup>; P = 0.142), ASES score (91.5 ± 4.4 vs 92.1 ± 3.0; P = 0.582); Rowe score (89.8 ± 4.0 vs 88.2 ± 5.8; P = 0.264), and instability persistence/recurrence (4.8% vs 2.4%; P = 0.624) respectively. Anterior gleno-humeral micro-instability, following single-event trauma in non-athletes, could be successfully-managed (in a way similar to that of type-V SLAP lesion of the recurrent anterior gleno-humeral dislocation/macro-instability) via in-SALT-augmented suture-anchor antero-inferior capsulo-labral repair with comparable outcomes. The study was approved by the Institutional Committee of Scientific Research and Ethics (IRB: 2/2023 ORTH 30-3). III.
