Purpose: The aim of this study was to describe the results of an arthroscopic Trillat procedure utilized to treat patients with symptomatic antero-inferior shoulder instability associated with hyperlaxity., Methods: A retrospective review was performed on 19 consecutive shoulders (17 patients, 2 bilateral) who underwent a Trillat procedure combined with anterio-inferior capsulolabral plasty from 2016 to 2019. Patients included in the study presented with shoulder instability combined with shoulder hyperlaxity and no glenoid or humeral bone loss. Clinical assessment included range of motion, apprehension, and instability tests. Outcome measures Constant-Murley score (CMS) scale, Walch-Duplay, ROWE, Subjective Shoulder Value (SSV), Visual Analogue Scale (VAS). Post-operatively, healing of the coracoid osteoclasy was evaluated by CT scan., Results: The mean follow-up was 24.8 months (range, 12-51). Post-operatively, none of the patients experienced a recurrent dislocation or subluxation and the anterior apprehension test was negative in all shoulders. Post-operative motion deficits of 22.1° ± 15.8 [p < 0.05] and 12.4° ± 10.1 [p < 0.05] loss were documented for ER1 and ER2, respectively. All functional scores exhibited significant improvements. Post-operative CT scan was available in 16 shoulders and revealed coracoid union in 15/16 shoulders and an asymptomatic fibrous non-union without coracoid or implant migration in one patient., Conclusion: The arthroscopic Trillat procedure combined with an antero-inferior capsulolabral plasty is effective in preventing recurrent instability and eliminating shoulder apprehension among patients suffering from anterior and or inferior hyperlaxity., Level of Evidence: Level IV., (© 2021.
