dc.description.abstractPurposeTrochlear dysplasia is one of the main risk factors for recurrent patellar dislocation. The Dejour classification identifies four categories that can be used to classify trochlear dysplasia. The purpose of this study is to evaluate the inter- and intraobserver reliability of the Dejour classification for trochlear dysplasia. The hypothesis was that both intra- and interobserver reliability would be at least moderate.MethodsThis is a cross-sectional, reliability study. Twenty-eight 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-D). There were three rounds: one with only computed radiograph (CR), one with only magnetic resonance imaging (MRI) and one with both. Inter- and intraobserver reliability were calculated using kappa coefficient (0-1).ResultsThe mean age of patients was: 14.6 years; 60% were female and 53% had open physis. The interobserver reliability kappa probabilities were 0.2 (CR), 0.13 (MRI) and 0.12 (CR and MRI). The intraobserver reliability kappa probabilities were 0.45 (CR), 0.44 (MRI) and 0.65 (CR and MRI).ConclusionThe Dejour classification for trochlear dysplasia has slight interobserver reliability and substantial intraobserver reliability.Level of EvidenceLevel I.
