Redislocation with a bony bankart lesion after arthroscopic Bankart repair.

This case report presents a traumatic dislocation after an arthroscopic Bankart repair in which the repair site was intact and failure occurred through a new bony interval. The new bony Bankart lesion was identified 3 years after the initial arthroscopic repair. This highlights the issue of whether a traumatic redislocation after a surgical repair for recurrent shoulder instability represents a failure of repair or a reinjury.
