abstract = {BACKGROUND: The purpose of this study was to assess the outcomes 

 of a new arthroscopic Trillat technique at a 2-year follow-up. 

 Our current hypothesis was that this technique could be used for 

 the effective treatment of chronic post-traumatic unidirectional 

 anterior shoulder instability, and that the recurrence and 

 complication rates, external rotation, and functional outcomes 

 would be as good as those of the reference technique. METHODS: 

 Between April 2012 and August 2016, all patients older than 16 

 years who underwent the arthroscopic Trillat technique for 

 unidirectional chronic post-traumatic anterior shoulder 

 instability at the Dijon University Hospital (France), after the 

 failure of well-conducted medical and rehabilitation treatment 

 with at least 24 months of follow-up, were included. Criteria 

 for noninclusion were association with posterior and/or inferior 

 instabilities, voluntary instabilities, and glenoid bone loss 

 greater than 20%. Patients attended follow-up with their 

 surgeon before the intervention, in the immediate postoperative 

 period, at 6 weeks, 3 and 6 months, and then by an independent 

 observer for the last evaluation. Patients were then examined 

 clinically with scores such as Constant, Rowe and Walch-Duplay 

 scores, and subjective shoulder value, for shoulder range of 

 motion, and radiographically (anteroposterior and Lamy's lateral 

 x-rays of the operated shoulder). RESULTS: Forty-nine patients 

 and 52 shoulders were included, with a mean follow-up of 40 

 months (range, 24-71 months). The recurrence rate of instability 

 was 3.8% (2 of 52). No conversion to arthrotomy was necessary. 

 No intraoperative complications, postoperative neurological 

 lesions, or sepsis were observed. The mean Constant score was 

 92.1 (77.5-100) points, Walch-Duplay 82.9 (40-100), Rowe 81.73 

 (5-100), and subjective shoulder value 86.1 (50-100) at the last 

 follow-up. The arm at side external rotation limitation averaged 

 8.4° (-25° to 40°) and the external rotation with 90° arm 

 abduction limitation 0.34° (-5° to 15°). Forty-one patients 

 (79%) resumed their sports activity at the same level. Fifty 

 patients (96%) were satisfied to very satisfied. One patient 

 developed nonunion of the coracoid process and subsequently 

 underwent a Latarjet procedure with a good outcome. CONCLUSIONS: 

 The arthroscopic Trillat procedure offers good outcomes as a 

 first-line treatment for chronic anterior post-traumatic 

 glenohumeral instability. It should be excluded in cases of 

 glenoid loss greater than 20%.},
