For patients with traumatic anterior shoulder instability, we have been performing arthroscopic Bankart procedures using suture anchors. Here, we reported the therapeutic results of the patients with some intraarticular lesions except for Bankart lesion compared to that on the patients with only Bankart lesion. The subjects were 27 patients. Their mean age at the time of surgery was 31.8 years old. Almost all cases engaged in sports activities. On preoperative radiographic findings, Bankart lesions were observed in all patients. During arthroscopic procedure, intraarticular lesions, except for Bankart lesion, consisted of SLAP lesion in 20 cases, rupture of the capsule in 5 cases, and joint mice in 5 cases. The mean follow-up period was 2 years and 3 months and the therapeutic results were evaluated according to the JOA score and JSS shoulder instability score. Meanwhile, the therapeutic results of the patients with only Bankart lesion were evaluated as a comparison group. Of 27 patients, no patient developed subluxation or dislocation after surgery. The final therapeutic results were evaluated as 95.1 points in JOA score and 90.8 points in JSS shoulder instability score. The comparison group was evaluated as 97.2 points in JOA score and 96.1 points in JSS shoulder instability score. In the postoperative range of motion, external rotation was restricted by about 12.3 degrees on average, compared to the non-affected side. However, the restriction in the comparison group was 5.4 degrees compared to the non-affected side. There was no difference in shoulder instability between the subjects and the comparison group, postoperatively. However, the postoperative external rotation was restricted higher in the subjects compared to the comparison group.
