The utility of standing knee radiographs for detection of lipohemarthrosis: comparison with supine horizontal beam radiographs
"The Utility of Standing Knee Radiographs for Detection of Lipohemarthrosis: Comparison with Supine Horizontal Beam Radiographs" was published in European Radiology (2023 Impact Factor; 7.034, Q1 indexed Journal).
Lipohemarthrosis, characterized by the presence of a fat-fluid level, is a crucial finding in patients with acute trauma, indicating an intra-articular fracture. Our retrospective study compared the sensitivity of standing and supine lateral knee radiographs in detecting lipohemarthrosis. The results of our study revealed that standing lateral knee radiographs exhibited a higher sensitivity (95.5%) in detecting lipohemarthrosis compared to supine lateral radiographs (38.5%) (p<0.001). This finding highlights the importance of utilizing standing lateral radiographs for the diagnosis of lipohemarthrosis, which indicates the presence of occult intra-articular fractures in patients with knee trauma. Moreover, our research demonstrated good-excellent interobserver agreement in the detection of lipohemarthrosis, further validating the reliability of this technique.
These findings highlight the significance of our study and its implications for clinical practice. Our results suggest that knee trauma patients, whenever feasible, should be evaluated using standing lateral radiographs to enhance the detection of lipohemarthrosis. By leveraging this technique, clinicians can improve diagnostic accuracy and promptly identify intra-articular fractures, enabling appropriate management and treatment decisions for patients with knee trauma.
