Patients with atraumatic multidirectional instability, clinical ligamentous laxity, or previous shoulder surgeries were excluded. Variables analyzed included age, sex, body mass index, contact sports participation, number of dislocations (&lt;1, 1, 2, &gt;2), direction of instability, labral tear size, time to surgery, number of anchors, and concomitant procedures. Complex labral tears involved &gt;120\u00b0 of the glenoid rim. Cohorts of \u201csimple\u201d anterior or posterior tears (&lt;120\u00b0) were used for comparison.

In all tear size groups, it was more common to have &gt;2 dislocations than \u22642 dislocations (120\u00b0 = 48.6%, 240\u00b0 = 40.4%, 360\u00b0 = 83.3%), but these differences were not statistically significant (\n                      <jats:italic>P<\/jats:italic>\n                      = .067). Time from first injury\/instability event to surgery (in months) was not a predictor of tear size (simple = 45 \u00b1 70 months, complex = 38 \u00b1 67 months). There was no statistical difference between tear size groups and patient demographics in sex, contact sport participation, tobacco use, instability direction (anterior versus posterior), body mass index, age, or association of concomitant procedures. The number of anchors used was the only variable found to correlate with tear size (\n                      <jats:italic>P<\/jats:italic>\n                      &lt; .001).\n
