Functional and Radiological Outcomes of Open Versus Arthroscopic Latarjet for Anterior Shoulder Instability.

Objectives: The purpose of this study is to compare the clinical, functional and radiographic outcomes among 42 patients with anterior shoulder instability treated with either the open or arthroscopic Latarjet procedure.

Materials and methods: Between 2011 and 2018, we treated 42 patients with anterior shoulder instability, 19 underwent the open Latarjet procedure (OLP) and 23 underwent the arthroscopic Latarjet procedure (ALP). In the OLP group, 17 patients were males, with a mean age of 21.3 years (range: 16-37 years ) and a mean follow-up of 6.2 years (range: 5.5-7.2 years). In the ALP group, 20 patients were males, with a mean age of 20.6 years (range: 17-31 years) and a mean follow-up of 2.5 years (range: 2-3.1 years). All procedures were performed by a single surgeon. Functional outcomes were assessed using the University of California-Los Angeles (UCLA) shoulder score and the constant score (CS). Radiographic evaluations included standard radiographs and computed tomography (CT) scans. The two groups were compared to analyze differences in outcomes.

Results: All patients returned to their pre-injury level of activity. The arthroscopic Latarjet procedure resulted in better graft integration and inferior screw positioning. No major complications were reported in either group.

Conclusions: Anterior shoulder instability remains a complex issue in orthopedics regarding the optimal management approach. However, this study suggests that the arthroscopic Latarjet procedure offers advantages, including superior visualization and effective restoration of damage.
