The tibial tubercle–trochlear groove distance: a comparison study between EOS and MRI in the paediatric population

Objective This study aims to compare the relative reliability and accuracy of TT-TG measurements in EOS with that of MRI in a paediatric population. Methods Patients were included if they underwent both an MRI and EOS scans and were under the age of 16. Two authors recorded the TT-TG distances on ea...

description Objective This study aims to compare the relative reliability and accuracy of TT-TG measurements in EOS with that of MRI in a paediatric population. Methods Patients were included if they underwent both an MRI and EOS scans and were under the age of 16. Two authors recorded the TT-TG distances on each modality at two separate time points. In the EOS images, the distance between the two points was measured in the horizontal 2D plane. In the MRI images, it was done in the plane referenced by posterior femoral condylar axis. The intra- and inter-rater reliability was assessed in each modality and between modalities. Results Twenty-seven patients (30 knees), 14 males, and 13 females with an average age of 13 years (range: 7–16 years) were included in the study. The mean TT-TG distance on EOS scan and MRI scan was 14 mm. On inter- and intra-observer analysis, both imaging modalities had excellent reliability (0.97 ICC for EOS and 0.98 ICC for MRI inter-observer) and repeatability (0.98–0.99 ICC for EOS and 0.99 ICC for MRI for intra-observer). However, on comparing the two imaging modalities (EOS vs MRI), the ICC was fair (0.56 ICC for rater 1 and 0.65 ICC for rater 2). Conclusion While the EOS TT-TG measurements were precise and reproducible, they were only moderately comparable to MRI TT-TG measurements. Consequently, EOS TT-TG measurements should not be used for decision-making without the development of EOS-specific TT-TG values that indicate the need for distal realignment surgery. Level of evidence Level II.
