Open Latarjet procedure for failed arthroscopic Bankart repair.

INTRODUCTION: This retrospective study assessed the functional results of open Latarjet operation for recurrence of instability after arthroscopic Bankart repair in a consecutive series of patients.

MATERIALS AND METHODS: Fifty two patients (mean age 28.4 [range 17-62] years, 45 men) were operated on using open Latarjet operation after one (n=46) or two (n=6) failed arthroscopic Bankart repairs. The indication for revision surgery was recurrent dislocation or subluxation. Fifty patients had a Hill-Sachs lesion and 32 patients had glenoid bone lesions on plain radiographs. No attempt was made to grade the severity of bony pathology. Functional outcome and stability of 49 shoulders were assessed after an average follow-up of 38 (range 24-85) months using Western Ontario Shoulder Instability (WOSI) score, Oxford shoulder instability score, and subjective shoulder value (SSV).

RESULTS: Forty-two patients had a stable shoulder at follow-up. Seven of 49 (14%) had symptoms of instability; one patient had recurrent dislocation, and six patients had subluxations. Mean WOSI, Oxford, and SSV scores were 83.9, 19.9, and 84.9, respectively. All scores were significantly better in patients who had a stable shoulder compared with those who had an unstable shoulder (WOSI 86.8 vs. 64.3; Oxford 18.2 vs. 30.8; and SSV 88.3 vs. 61.7; P<0.01). One patient needed a reoperation. There were no intraoperative or postoperative complications.

CONCLUSIONS: Open Latarjet operation is a good option for failed arthroscopic Bankart repair. The instability recurrence rate is acceptable and the reoperation rate was low.

LEVEL OF EVIDENCE: Level IV, retrospective case series.
