Abstract

Background: The Bankart and the Latarjet procedures are 2 of the most commonly utilized surgical techniques to treat anterior shoulder instability. However, the long-term outcomes after these procedures remain unclear, and there is not enough information regarding arthroscopic Latarjet. Purpose: To analyze long-term outcomes of patients with anterior glenohumeral instability managed with an arthroscopic Bankart or Latarjet procedure. Study Design: Cohort study; Level of evidence, 3. Methods: Patients who underwent an arthroscopic Latarjet were matched-paired in a 1:1 ratio with patients who underwent an arthroscopic Bankart procedure at a single institution between 2007 and 2012. Recurrence at the time of follow-up as well as intraoperative and postoperative complications were recorded and compared between the 2 groups. Postoperative status was assessed at the final follow-up using the Rowe score, the Western Ontario Shoulder Instability Index (WOSI), the Subjective Shoulder Value, and the return-to-sport rate. Results: A total of 80 patients, 40 patients in each group, were included (overall mean age, 26.5 ± 15.4 years). The mean follow-up was 13.2 years (range, 10-17 years). The recurrence rate was significantly higher in the Bankart group compared with the Latarjet group (35% vs 10%, respectively; P = .009). The mean estimate for the cumulative proportion of stable shoulders at 15-year follow-up was 64.4% in the Bankart group and 89.6% in the Latarjet group ( P = .008). Revision surgery because of instability was necessary in 8 (20%) patients in the Bankart group and 2 (5%) in the Latarjet group ( P = .41). There was no significant group difference in complication rate (15% in the Bankart group vs 17.5% in the Latarjet group; P = .48). The WOSI score was significantly better in patients treated with arthroscopic Latarjet ( P = .004). More than half of the patients were able to completely return to their previous sport (52.5%), with no significant difference between groups. Conclusion: Arthroscopic Latarjet was associated with a significantly lower recurrence rate and better postoperative WOSI score and sports activity level at long-term follow-up compared with arthroscopic Bankart, without any greater risk of complications.
