Functional outcomes after open versus arthroscopic Latarjet procedure: A prospective comparative study

Abstract

IntroductionThe Latarjet procedure provides effective stabilization of chronically unstable shoulders. Since this procedure is mainly performed in a young athletic population, the functional impact is significant. Published data does not shed light on the time needed to recover work-related or sports-related function. Performing this procedure arthroscopically may improve functional recovery. This led us to carry out a prospective, multicenter study to compare the functional recovery after arthroscopic versus open Latarjet procedure. Material and methodsBetween June and November 2014, 184 patients were included in a prospective multicenter study: 85 in the open group and 99 in the arthroscopy group. The patients were evaluated preoperatively with the WOSI score. The early postoperative pain was evaluated on D3, D7 and D30. The WOSI score was determined postoperatively at 1, 3, 6 and 12 months of follow-up. ResultsThe functional scores of the shoulder in both cohorts were identical overall preoperatively. In the immediate postoperative period, the arthroscopy group had statistically lower pain levels on D3 and D7. The postoperative WOSI was improved in both groups at 3 months, then continued to improve until it reached a plateau at 1 year. The WOSI score was better in the arthroscopy group at 3 months, but better in the open group at 6 months. ConclusionThis study found that a Latarjet procedure performed arthroscopically generates less immediately postoperative pain than when it is performed as an open procedure. The Latarjet procedure (whether open or arthroscopic) improves shoulder function, with normal function returning after 1 year.
