%X UNASSIGNED: Post-arthroscopic Bankart repair failure/re-dislocation rates are influenced by several risk factors, including anatomic defects. There is limited evidence on the role of anatomic defects, especially for Hill-Sachs size in on-track lesions. This study aimed to assess glenoid bone loss, Hill-Sachs lesion and labral tear size and evaluate their contribution to post-operative instability after a primary repair.
UNASSIGNED: Across 169 patients with on-track Bankart lesions who underwent primary arthroscopic Bankart repair from 2010 to 2015, this study matched 14 failure with 14 non-failure cases based on age/gender. Patient demographics, pre-operative radiological parameters (including size of glenoid bone loss and Hill-Sachs lesion) and labral tear size were compared between the failure and non-failure groups.
UNASSIGNED: All patients were male with a mean age of 21.01 ± 4.97. Significantly greater glenoid bone loss (p = 0.024) and labral tear size (p = 0.039) were found in the failure group. However, there was no significant difference in mean volume of Hill-Sachs lesion between the two groups (p = 0.739).
UNASSIGNED: Extensive glenoid bone loss and labral tears are risk factors for post-arthroscopic Bankart failure. However, the size of Hill-Sachs lesion is not a risk factor for failure, in a specific group of on-track Hill-Sachs lesions.
UNASSIGNED: Retrospective Study, Level IV.
