Arthroscopic Repair of Small and Medium-Sized Bony Bankart Lesions

Background:There has been no study about treatment guidelines for arthroscopic repair according to the size of bony Bankart lesions of less than 25% of the glenoid width.Purpose:To evaluate the results of arthroscopic repair for bony Bankart lesions managed with different repair techniques based on their size.Study Design:Case series; Level of evidence, 4.Methods:Between March 2005 and February 2009, 44 of 52 consecutive patients with bony Bankart lesions with a size of less than 25% of the entire glenoid were managed with an arthroscopic approach. Of those patients, 34 (77%) were available for outcome analysis at a minimum 24 months’ follow-up (mean, 34 months; range, 24-60 months). The size of the fragment was measured by computed tomography (CT) and classified as small (<12.5% of the inferior glenoid width) and medium (12.5%-25%). Sixteen lesions were classified as small (small group), and 18 were classified as medium (medium group). For small lesions, capsulolabral repair using suture anchors without ...
