PurposeTo compare the return-to-sport rate, functional outcomes, and complications of the "classic Latarjet" surgery with those of the "congruent arc Latarjet" surgery in athletes with recurrent glenohumeral instability and failed previous stabilization procedures.MethodsAll the included patients were operated between May 2009 and April 2017. The inclusion criteria were athletes with recurrent anterior glenohumeral instability, a glenoid bone defect greater than 20%, at least 1 previous failed stabilization surgery operated with the classic or the congruent-arc Latarjet procedures, and a minimum 2 years of follow-up. Return to sports, range of motion (ROM), the Rowe score, a visual analog scale for pain, and the Athletic Shoulder Outcome Scoring System score were used to assess functional outcomes. Complications were also evaluated.ResultsA total of 135 athletes were included in the study (55 patients were operated with the classic technique and 80 with the congruent arc technique). The mean follow-up was 40.3 months (range, 24-88 months) and the mean age was 26.5 years (range, 18-45 years). Overall, 87% were able to return to sports and 92% returned at the same level. No significant difference regarding return to sports was found between the groups. No significant difference in shoulder ROM was found between preoperative and postoperative results. The Rowe, visual analog scale, and Athletic Shoulder Outcome Scoring System scores showed statistical improvement after operation (P < .001). No significant difference in shoulder ROM and functional scores was found between patients operated with the classic and congruent arc procedures. There were 6 recurrences (4%). There was no significant difference in the recurrence rate between groups. The bone block healed in 92% of the cases.ConclusionsIn athletes with recurrent anterior glenohumeral instability and a failed previous operative repair, the Latarjet procedure produced excellent functional outcomes and most athletes returned to sport at their preinjury level with a very low rate of recurrences, regardless of whether the Latarjet was performed with the classic or with the congruent arc technique.Level Of EvidenceRetrospective comparative study; Level of evidence, 3.Copyright © 2020 Arthroscopy Association of North America.
