Abstract
The purpose of this study was to compare the clinical results of open Bankart repair (open group) and arthroscopic Bankart repair (arthroscopic group) using Panalok suture anchors for traumatic anterior shoulder instability. We studied retrospectively 66 shoulders in the open group and 86 shoulders in the arthroscopic group. All patients had typical Bankart lesion and underwent open or arthroscopic Bankart repair, and were observed more than 2 years postoperatively. The average age at the time of surgery was 25.4 years old in the open group and 24.9 years old in the arthroscopic group. 41 cases in the open group and 54 cases in the arthroscopic group actively participated in sports activities. The average follow-up was 28.5 months in the open group and 27.2 months in the arthroscopic group. We evaluated the clinical outcome using the JSS shoulder instability score (instability score), Rowe score, recurrence rate and return to sports activities. The instability score and Rowe score were 81.4 and 79.8 in the open group, and 87.5 and 83.8 in the arthroscopic group at the time of final investigation. 9 cases in the open group and 10 cases in the arthroscopic group had experienced re-dislocation. 35 cases (85.4%) in the open group and 49 cases (90.7%) in the arthroscopic group returned to their preoperative sports activities on average 6.8 and 5.9 months postoperatively. The instability score, especially ROM score of the score, and ROM score of Rowe score were significantly higher in the arthroscopic group compared with the open group. Arthroscopic Bankart repair showed similar results to the open Bankart repair.
