The Dejour classification identifies four categories that can be used to classify trochlear dysplasia. The purpose of this study is to evaluate the inter\u2010 and intraobserver reliability of the Dejour classification for trochlear dysplasia. The hypothesis was that both intra\u2010 and interobserver reliability would be at least moderate.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      This is a cross\u2010sectional, reliability study. Twenty\u2010eight examiners from the International Patellofemoral Study Group 2022 meeting evaluated lateral radiographs of the knee and axial magnetic resonance images from 15 cases of patellofemoral instability with trochlear dysplasia. They classified each case according to Dejour's classification for trochlear dysplasia (A\u2013D). There were three rounds: one with only computed radiograph (CR), one with only magnetic resonance imaging (MRI) and one with both. Inter\u2010 and intraobserver reliability were calculated using\n                      <jats:italic>\u03ba<\/jats:italic>\n                      coefficient (0\u20131).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The mean age of patients was: 14.6 years; 60% were female and 53% had open physis.
