Abstract
The purpose of this study was to evaluate the clinical results of arthroscopic Bankart repair for traumatic anterior shoulder instability and to compare the outcome in patients who have Bankart lesions versus those with anterior labroligamentous periosteal sleeve avulsion (ALPSA) lesions. This study included 86 patients (86 shoulders), 70 male and 16 female, who underwent arthroscopic Bankart repair for traumatic anterior shoulder instability, by use of suture anchors, and they were observed for more than 2 years postoperatively. In 64 shoulders a Bankart lesion was repaired and in 22 shoulders an ALPSA lesion was repaired. The average age at the time of surgery was 24.2 years old in the Bankart lesion group (Classic Bankart group) and 26.8 years old in the ALPSA lesion group (ALPSA group). The average follow-up was 27.7 months in the Classic Bankart group and 25.5 months in the ALPSA group. JSS shoulder instability score (JSS-SIS), Rowe score, and recurrence rate were evaluated. JSS-SIS and Rowe score were 87.8 and 83.8 in the Classic Bankart group, and 86.5 and 81.8 in the ALPSA group respectively at the time of final investigation. 8 cases in the Classic Bankart group and 2 cases in the ALPSA group had experienced re-dislocation. In the several factors, there was no statistical difference among the groups. This study suggested that the clinical results of arthroscopic Bankart repair for traumatic anterior shoulder instability were not related to the type of Bankart lesion.
