All patients with a single labrum tear, an MRI within 6\u2009months of surgery, and historical tear measurements or measurable intraoperative photographs were included in the study. Glenoid labrum tear size was noted using the clockface convention described in \u201chours.\u201d When clockface measurements were not reported on MRI reads, measurements were made by a radiologist. When clockface measurements were not reported in operative notes, measurements were made by an orthopaedic surgeon using intraoperative photographs. A paired\n t<\/jats:italic>\n test was used to evaluate any difference between the MRI and intraoperative measurements.\n <\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Two hundred sixteen glenoid labral tears from 211 patients met inclusion criteria. Average age was 27.2\u2009\u00b1\u200911.8\u2009years, 68.5% of patients were men, and 56.9% of glenoid labrum tears were right\u2010sided. On average, MRI measurements exceeded intraoperative measurements (4.15\u2009\u00b1\u20092.90\u2009hours vs 2.80\u2009\u00b1\u20091.59\u2009hours) with an average difference of 1.36\u2009\u00b1\u20093.09\u2009hours (95% confidence interval\u2009=\u20090.94\u20101.77,\n P<\/jats:italic>\n \u2009<\u2009.001) and a correlation of 0.154 (\n P<\/jats:italic>\n \u2009=\u2009.023). A greater difference in measurement was observed among men compared with women (1.64 vs 0.74\u2009hours,\n P<\/jats:italic>\n \u2009=\u2009.044).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n MRI overestimated glenoid labrum tear size compared with intraoperative measurements and differed substantially between the 2 modalities on a case\u2010by\u2010case basis, with men displaying a larger discrepancy in measurement difference than women. These findings indicate that MRI may be more appropriately used as a categorical tool for confirming the presence of glenoid labral tears, rather than as a precise measure of tear size.<\/jats:p>\n
