Diagnostic evaluation of open knee injuries: a comparison of arthrography and CT scans.
Eur J Orthop Surg Traumatol
November 2024
Department of Orthopaedics, Queen Savang Vadhana Memorial Hospital, 290 Jermjompol, Si Racha, Chonburi, 20110, Thailand.
Article Synopsis
- The study examines knee arthrography as a potential diagnostic tool for open knee injuries, comparing its effectiveness to the gold standard of CT scans, which have downsides like cost and radiation exposure.
- Conducted with 43 patients, the study found that CT scans diagnosed open knee injuries in 11.6% of cases, while knee arthrography showed high sensitivity (83.3%) and specificity (96.5%).
- The results suggest that knee arthrography could be a safer and more cost-effective alternative to CT scanning for diagnosing open knee injuries, especially when considering the risks of radiation.
Femoroacetabular Impingement: Preoperative Planning and Postoperative MR Imaging Evaluation.
Magn Reson Imaging Clin N Am
February 2025
Faculty of Medicine, Department of Radiology, Balgrist University Hospital, University of Zürich, Forchstrasse 340, Zürich 8008, Switzerland.
Imaging plays a critical role in the preoperative and postoperative evaluation of patients with femoroacetabular impingement. Non-contrast MR imaging and direct magnetic resonance arthrography of the hip are the modalities of choice for the preoperative assessment of chondrolabral lesions. The MRI protocol should include radial images for detailed analysis of the cam deformity and fast sequences covering the pelvis and knee for measurement of femoral torsion.

December 2024
Department of Orthopedic Surgery, Iwate Medical University, Iwate, Japan.
Background: This study aimed to clarify the characteristic features of the anteroinferior and posterosuperior popliteomeniscal fascicles (aiPMF and psPMF, respectively) and popliteal hiatus using three-dimensional (3D) reconstructions of 7 T magnetic resonance imaging (MRI) arthrography.
Methods: Six knees from human cadavers fixed using the Thiel embalming method were examined using 7 T MRI arthrography. 3D Images of the structures around the popliteal hiatus were reconstructed.
Significant systematic bias of alpha angles measured on MRI compared to various radiographic views in patients with femoroacetabular impingement syndrome.

September 2024
Department of Orthopedic Surgery, New York University Langone Health, New York, New York, USA.
Purpose: The aim of this study was to assess the inter-rater reproducibility and inter-method comparability of hip alpha angle measurements on magnetic resonance imaging (MRI)/magnetic resonance arthrography (MRA) and plain radiographs in patients with femoroacetabular impingement syndrome (FAIS).
Methods: A cross-sectional study of patients who were diagnosed with symptomatic FAIS underwent preoperative MRI/MRA with axial oblique and/or radial plane imaging and had preoperative radiographs with anterior-posterior (AP), 45° Dunn and 90° Dunn views. Alpha angle measurements were performed independently by two musculoskeletal radiologists.
Pigmented Villonodular Synovitis of the Shoulder: A Case Report and Literature Review.
Am J Case Rep
August 2024
Department of Orthopaedics, University of Patras, School of Medicine, University Hospital of Patras, Patras, Greece.
BACKGROUND Pigmented villonodular synovitis is a rare clinical entity, with 2-3% of all PVNS cases affecting the shoulder. Diagnosis is challenging and can elude clinicians for years, with definitive treatment involving arthroscopic or open synovectomy. CASE REPORT A 50-year-old woman presented with left shoulder pain persisting for 2 years.
