The congruent arc latarjet procedure – Its functional outcomes in recurrent anterior shoulder dislocation with critical glenoid bone loss

Background: Recurrent shoulder dislocation leading to shoulder instability is a cumbersome clinical problem for patients and orthopedicians. Due to a lack of knowledge in young patients of developing countries, there is a delay in presentation from the first time of dislocation. The aim of this retrospective study was to evaluate the functional and radiographic outcomes of patients with shoulder instability after the Congruent Arc Latarjet procedure. Methods: From January 2018 to November 2021, 20 patients with history of recurrent shoulder dislocation having glenohumeral instability were treated surgically in our institute. Open Congruent Arc Latarjet procedure was performed in 20 patients. Functional outcomes were assessed preoperatively and postoperatively based on American Shoulder and Elbow Surgeons (ASES) score, the visual analog scale (VAS) for pain, ROWE score, and Active range of motion in the diseased shoulder. Results: Twenty shoulders of 20 patients were evaluated for a mean period of 24 months postoperatively. At the time of the latest consultation, the range of motion and the shoulder functional evaluations based on ROWE score which was 89.64 ± 5.71 (range 80–95) improved from 20.36 ± 8.87 (range 10–30), p = 0.001. The mean preoperative ASES score was 22.60 ± 1.09 (range 20.6–25) which improved to 72.50 ± 7.33 (range 52.8–77.2), p = 0.001, which is definitely improved. The overall re-dislocation rate was 0% (0 of 20). In our study, 60% had excellent outcomes, 30% had good outcomes, and 10% had fair outcomes. Conclusion: The Congruent Arc Latarjet procedure for the treatment of recurrent shoulder dislocation with glenoid bone loss of >20% is a successful and efficient method with better outcomes in daily work profile and no further episode of redislocation.
