Abstract

Recently, arthroscopic Bankart repair has frequently been used as a treatment for anterior instability of the shoulder joints. We have also performed arthroscopic Bankart repair using absorbable suture anchors. We encountered three patients in whom the anchor hole remained and had enlarged on MR images taken three months after surgery. We have used PANALOKTM anchors for arthroscopic Bankart repair since 2000. In an anchor type in which tension is imposed on the suture to lock the anchor hole as the PANALOKTM anchor does, when slight absorption occurs, it is likely to loosen, causing a slight shift of the anchor. Moreover, the mechanical effect may enlarge the anchor hole. In our investigation of MR images, enlargement of the anchor hole was found in three of 28 shoulders (11%). Three months after surgery, a subjective feeling of instability was found in two of three shoulders (67%). Therefore, we concluded that it was necessary to follow -up such cases carefully.
