Arthroscopic Latarjet procedure: analysis of the learning curve.

BACKGROUND: The arthroscopic Latarjet procedure is an innovative technique that aims to combine the optimal results of the original open approach with those of arthroscopic stabilization. METHODS: We evaluated the learning curve and the preliminary results of the first 30 patients (29 males, 1 female; mean age 32 years, range 21-52) subjected to an arthroscopic Latarjet procedure at a mean follow-up of 13 months (range 6-22). RESULTS: Operative time fell significantly from 132 to 99 min (p < 0.001, t test) in the last 15 patients compared with the first 15 without significant differences in terms of Rowe score, patient satisfaction, complications, or graft placement. There were 21 (70 %) excellent and 9 (30 %) good outcomes according to the Rowe score. All complications (10 %) correlated with age >40 years (p = 0.002, Fisher's exact test). CONCLUSIONS: The arthroscopic Latarjet procedure is a standardized, hence reproducible technique whose complexity makes it suitable only for surgeons with solid experience in arthroscopy and shoulder surgery.
