It was reported on for utility the use of various suture anchors with arthroscopic Bankart repair. It was useful in MRI with abduction and external rotation (ABER-MRI) evaluation of the Bankart lesions. The aim of this study was to evaluate arthroscopic Bankart repaired condition after ABER-MRI with metal or absorbable anchors and to examine the utility for this more than 6 months later. We evaluated with ABER-MRI 21 shoulders treated by an arthroscopic Bankart repair with a knotless or absorbable anchor(14 men and 7 women). The average age at operation was 26.2 years old (17-46 years old). The follow-up after an arthroscopic Bankart repair was 6 months. The used anchors were 10 metal and 11 absorbable. The evaluation items were compared according to (1) each anchors of image evaluation possibility with ABER-MRI. (2) evaluation with ABER-MRI and normal position MRI. (3) 3 group classified by ABER - MRI examined the correlation with the clinical results. We evaluated 18 of 21 shoulders with ABER-MRI, and to be 7 of 10 metal anchors(70%), 11 of 11 absorbable anchors (100%). In 7 of 18 shoulders that we were able to evaluate with ABER-MRI, the normal position MRI was impossible to evaluate. In repaired condition evaluated by ABER - MRI in 18 shoulders, type I had 14 shoulders (77.8%), type II had 3 shoulders (16.7%), type III had 1 shoulder. The good shoulder results were all type I, and the re-subluxation and the underachivement shoulders were type II, III. MRI evaluation possibility is more useful for an absorbable anchor than a metal anchor in postoperative evaluation. In the good results condition with ABER-MRI, the clinical results are good.
