Surgical repair of a Bankart lesion requires thorough recognition of the capsulolabral attachment and adequate visualization for suture anchor repair. The glenoid labrum usually detaches from its capsule and bony attachment anteriorly and inferiorly; however, the labral and capsule detachment can sometimes extend beyond this zone of injury. Identification and repair may require additional viewi...
