Diagnostic Accuracy of MRI Evaluation of Patellar Position According to the Physeal Line in Pediatric Patients

Aim: Abnormal positioning of the patella, which superior position is defined as patella alta (PA), whereas inferior baja (PB). Most measurements patellar evaluations are time-consuming. In this study, we aimed to examine diagnostic accuracy visual evaluation according physeal line and determine inter- intraobserver agreement in MRI examinations. Material Methods: Knee examinations performed between 2019-2021 with different knee symptoms prediagnoses were retrospectively analyzed study. As a reference test, Insall-Salvati Ratio was calculated by following formula: Tendon length/patellar length. Two methods used; physis (PLP) joint cartilage (PLC). Results: Three hundred sixty consecutive children aged 60-215 months included There excellent an both intra- interobserver on PLP PLC for two observers (κ > 0.800, all). When evaluated agreements groups, almost perfect detected 0.750, Diagnostic (Sensitivity 95.5%, specificity 87.2% observer 1, Sensitivity 94.7%, 2), also good 89.3%, 82.9% 88.1%, 85.5% 2). Conclusion: Even though direct radiography used diagnosis PA PB, it has been shown that can be pediatric patients daily practice. Instead time-consuming MRI, may kept mind use these our study practical accurate diagnosis.
