Summary
The added procedure of trough formation did not seem to improve the clinical result in terms of frank dislocation recurrence, however it seems to show less anterior apprehension in ABER position at final follow-up.

Abstract
Introduction
Trough formation on the anterior glenoid rim has been recently popular procedure, expected improved result in our clinical outcome of arthroscopic Bankart repair using suture anchors. The purpose of this study were (1) to analyze clinical and radiographic outcomes in patients who have undergone arthroscopic Bankart repair with suture anchors and (2) to compare the outcomes between the trough and non-trough group.
Material And Methods
We analyzed one hundred ninety five patients (196 shoulders) after arthroscopic Bankart repair at our institute from 2005 to 2011. One hundred sixteen patients (117 shoulders) were available for clinical and radiologic outcome evaluation at final follow-up (70.1%). The mean follow-up was 5 years (range, 2-8.8 years). From 2005 to 2007 no trough was made to the anterior glenoid rim and from 2007 to 2011 trough was made in all cases. (Trough group n=54, Non-trough group n=63). All other surgical procedure was identical. Clinical and functional outcomes were assessed with range of motion (ROM), pain visual analog scale(p-VAS), functional visual analog scale(f-VAS) and Rowe score in pre- and postoperatively. Anterior apprehension test were performed and shoulder range of motion (ROM) were recorded at final follow-up. Radiological outcome was evaluated with glenoid bone defect and Hill-Sachs lesion on MRI, gleno-humeral joint arthrosis using the Samilson-Prieto classification on plain radiograph.
Results
The overall clinical and functional outcomes improved significantly after operation. 8 patients (6.8%) showed recurrent instability, while 5 recurrences (4.3%) recurrences occurred after a trauma. 32 cases (27.4%) had a positive apprehension sign postoperatively on examination at the follow up. Radiologic findings showed 27 cases with mild arthritis (37 %) and 6 cases with moderate (8.2 %) and 0 cases with severe arthritis (0%). Subgroup analysis showed no significant clinical and functional outcomes between the two groups (P >.05). But, significant difference was found for apprehension (18.5% [10 of 54] for trough group vs 34.9% [22 of 63] for non-trough group) (P = .047). Difference in recurrence rate was also not significant with patients in trough group (5 of 54, 9.3%) and 3 patients in non-trough group (3 of 63, 4.8%) at the last follow-up examination (P >.05).
Conclusion
The added procedure of trough formation did not seem to improve the clinical result in terms of frank dislocation recurrence, however it seems to show less anterior apprehension in ABER position at final follow-up. Arthroscopic Bankart repair using suture anchors had relatively good clinical outcome with redislocation rate 6.8% at mean 5 year follow-up.
