1️⃣ PCL Stress Radiographs in Chronic Injuries:
- Due to the healing process, MRI examinations in patients with chronic PCL injuries might not fully reveal the extent of the deficiency.
- Stress radiographs offer a more objective method to assess the PCL's structural integrity.
- American Journal of Sports Medicine, December 2015; 43(12): 3077-92.
2️⃣Clinical Utility of PCL Stress Radiographs:
- These radiographs are useful clinical tools for evaluating the extent of PCL injury and determining the need for surgical intervention, especially in chronic conditions.
- Journal of Knee Surgery, April 2021; 34(5): 499-508.
3️⃣Interpreting PCL Stress Radiographs:
- Method: Measurements are taken from the tibia's posterior cortex to the femoral condyles' posterior cortex, compared with the unaffected knee.
- Findings:
- Radiology, October 2016; 281(1): 23-40.
4️⃣ Enhanced Detection of PCL Injury with Proton Density Images
- Limitation of T2-Weighted Images: Sole reliance on these images may overlook subtle pathological changes in the PCL, resulting in decreased sensitivity.
- The advantage of Proton Density Images is that they offer enhanced visibility of abnormal intermediate or fluid intrasubstance signals, making them superior for detecting subtle PCL changes.
