Abstract

Background: Previous studies of the reliability of classifications for superior labral anterior and posterior (SLAP) lesions suggest that intraobserver/interobserver reliability is poor. Purpose: The goals were to (1) evaluate intraobserver/interobserver reliability of the Snyder classification of labrum tears among experienced surgeons, (2) determine the effect of simplifying that classification into normal versus abnormal labrums, (3) determine the reliability of subdividing type II SLAP lesions, and (4) evaluate the effect of videotape quality on diagnostic confidence. Study Design: Cohort study (diagnosis); Level of evidence, 3. Methods: At 2 separate times, 5 experienced shoulder surgeons (all >10 years of practice) evaluated 90 videotapes of shoulder arthroscopy performed for SLAP lesions to identify lesion type, to grade video quality, and to determine degree of confidence in diagnosis. The results were compared for intraobserver reliability (κ analysis) and interobserver reliability (intraclass correlation coefficients) and effect of video quality on diagnostic confidence. Significance was set at P
