Arthroscopy-assisted Trillat procedure for anterior shoulder instability: Surgical technique and preliminary clinical results

The Trillat procedure performed as open surgery to treat anterior shoulder instability has been proven effective in preventing recurrences and restoring range of motion. An arthroscopically assisted variant of the Trillat procedure is described here, together with the preliminary clinical results in 18 patients treated between 2011 and 2014. After a mean follow-up of 24.7 ± 9.8 months, the clinical outcomes were very satisfactory, with a Walch-Duplay score of 81.5 ± 18.0, a Rowe score of 83.6 ± 16.0, and 94% of satisfied or very satisfied patients. Mean operative time was 55 ± 13 min. No recurrences were recorded. As an easily performed procedure that provides good clinical outcomes, the arthroscopically assisted Trillat procedure is a simple and reproducible alternative to arthroscopic Latarjet procedure, which is still reserved for highly experienced surgical teams.
