RESUMO
The objectives of this study on arthroscopic treatment of chronic anterior shoulder instability were the collection of the current practices for this indication, their development as reported in the literature, and the analysis of preliminary results on a multicenter prospective series of Bankart arthroscopic procedures undertaken using a common technique on patients selected based on the Instability Severity Index Score (ISIS). This procedure predominates in the English-speaking world, whereas the Latarjet protocol is preferred in France. The choice between the two seems to be cultural since neither technique could be demonstrated to be superior in an analysis of 171 responses to an Internet questionnaire in this study. The literature reports disappointing results in the Bankart arthroscopic procedure and recent articles have researched the predictive factors for its failure. Eleven centers prospectively included 125 patients from 1 December 2007 to 30 November 2008. The inclusion criteria were recurrence of anterior instability and an ISIS less than or equal to four points out of 10. All the selected patients underwent capsuloligamentous reinsertion with a common minimal technique of at least three anchors and four sutures with the same postoperative protocol. At a mean follow-up of 18 months, four patients (3.2%) had experienced recurrence. For the 84 patients reexamined at 1 year, the Walch-Duplay and Rowe scores were, respectively, 88.4 and 87.8 points out of 100. Subjectively, 88.1% of the patients declared they were satisfied and would undergo the intervention again. This study confirmed the use of the ISIS as a consultation tool. Only continuation of the study with a minimum follow-up of 3 years will allow us to validate the lower limit of the ISIS below which this technique could be proposed provided that it respects the technical prerequisite of at least four capsuloligamentous sutures.
