Effects of Bone Incorporation After Arthroscopic Stabilization Surgery for Bony Bankart Lesion Based on Preoperative Glenoid Defect Size

Background:Recurrent shoulder instability occurs more frequently after soft tissue surgery when the glenoid defect is greater than 20%. However, for lesions less than 20%, no scientific guidance is available regarding what size of bone fragments may affect shoulder functional restoration after bone incorporation.Purpose/Hypothesis:The purpose was to analyze how preoperative glenoid defect size and bone fragment incorporation alter postoperative clinical outcomes, we compared the functional outcomes of shoulders with and without bony Bankart lesion. It was hypothesized that differences in postoperative clinical outcomes between patients with and without bony fragments would be found only in patients with a larger glenoid defect.Study Design:Cohort study; Level of evidence, 3.Methods:A total of 223 patients who underwent arthroscopic stabilization surgery for recurrent anterior shoulder instability were divided into two groups based on the presence of anterior glenoid bone fragments. In each group, postoper...
