Tang et al [51] found that lateral tibial plateau depression of >11 mm and its specific part involvement on preoperative CT scans could help predict a higher risk of the lateral meniscus tear and the ACL avulsion fracture. MR Arthrography Knee With a radiographic diagnosis of tibial plateau fracture, MR arthrography of the knee is not performed to evaluate for additional bone or soft-tissue injury. MRA Knee With a radiographic diagnosis of tibial plateau fracture, MRA of the knee is not performed to evaluate for additional bone or soft-tissue injury. MRI Knee With a radiographic diagnosis of tibial plateau fracture, MRI would be the next best imaging modality to evaluate for the presence of additional radiographically occult fractures and/or internal derangements of the acutely injured knee. With its superb contrast resolution and multiplanar imaging capability, MRI is proven to be a highly accurate imaging modality in the evaluation of bone marrow contusions and occult fractures [27-29] as well as meniscal [21,26] and ligamentous injuries [21,31-34]. Bone Scan with SPECT or SPECT/CT Knee With a radiographic diagnosis of tibial plateau fracture, Tc-99m bone scan with SPECT/CT is not performed as the next best imaging study to evaluate for additional bone or soft-tissue injury. US Knee With a radiographic diagnosis of tibial plateau fracture, US is not performed as the next best imaging study to evaluate for additional bone or soft-tissue injury. Variant 6: Adult or child 5 years of age or older. Acute trauma to the knee. Mechanism unknown. Focal patellar tenderness, effusion, able to walk. Initial Imaging. CT Knee CT is not routinely used as the initial imaging study for the evaluation of acute trauma to the knee but is superior to knee radiographs in detection and classification of fractures [12]. MR Arthrography Knee MR arthrography is not routinely used as the initial imaging study for the evaluation of acute trauma to the knee.
