Introduction- Subscapularis augmented Bankart repair (SB) is a novel arthroscopic technique of tenodesis of upper 1/3rd fibers of subscapularis tendon to capsulo-labral repair of Bankart lesion. Treatment of Bony Bankart lesion with glenoid bone loss % (GBL%) 10%–20 % is still a grey zone where bone augmentation procedures are an overtreatment and capsulo-labral repair is associated with high recurrence. MethodologyA retrospective study of 30 patients with h/o anterior instability with GBL%<20 % were classified into two groups. SB group included patients managed with arthroscopic subscapularis augmentation while CB group included patients managed with arthroscopic capsulo-labral repair. These patients were followed up after a minimum of 24 months post-surgery and functional outcomes evaluated using WOSI, ASES and ROWE scores. ResultsPatients in the SB group showed superior functional outcomes for WOSI and ROWE scores. Considering postoperative shoulder pain, the median ROWE-P (pain) score was better for SB group (10/10) when compared to CB group (5/10). Patients under SB group were more comfortable with physical symptoms of their shoulder (WOSI-P average 60/1000) and were more likely to continue their recreational sports activity (WOSI- sports for SB 63.7 and CB 119.5. In our study, none of the 15 SB patients had any restriction in range of shoulder movements [ROWE-M score of 10]. Subscapularis augmented Bankart repair is associated with minimal restriction of shoulder range, better pain relief, better acceptability and smoother return to daily living and occupation and can be considered as a routine for every patient with GBL<20 %.
