Revision open Bankart surgery after arthroscopic repair for traumatic anterior shoulder instability.
BACKGROUND
Only a few studies have provided homogeneous analysis of open revision surgery after a failed arthroscopic Bankart procedure.


OBJECTIVE
Open Bankart revision surgery will be effective in a failed arthroscopic anterior stabilization but inevitably results in a loss of range of motion, especially external rotation.


METHODS
Case series; Level of evidence, 4.


METHODS
Twenty-six shoulders that went through traditional open Bankart repair as revision surgery after a failed arthroscopic Bankart procedure for traumatic anterior shoulder instability were enrolled for this study. The mean patient age at the time of revision surgery was 24 years (range, 16-38 years), and the mean duration of follow-up was 42 months (range, 25-97 months).


RESULTS
The preoperative mean range of motion was 173 degrees in forward flexion and 65 degrees in external rotation at the side. After revision surgery, the ranges measured 164 degrees and 55 degrees, respectively (P = .024 and .012, respectively). At the last follow-up, the mean Rowe score was 81 points, with 88.5% of the patients reporting good or excellent results. After revision surgery, redislocation developed in 3 shoulders (11.5%), all of which had an engaging Hill-Sachs lesion and associated hyperlaxity (2+ or greater laxity on the sulcus sign).


CONCLUSIONS
Open revision Bankart surgery for a failed arthroscopic Bankart repair can provide a satisfactory outcome, including a low recurrence rate and reliable functional return. In open revision Bankart surgery after failed stabilization for traumatic anterior shoulder instability, the surgeon should keep in mind the possibility of a postoperative loss of range of motion and a thorough examination for not only a Bankart lesion but also other associated lesions, including a bone defect or hyperlaxity, to lower the risk of redislocation.
