Analysis of Radiological Features of Lateral Femoral Impaction Fracture / Lateral Femoral Notch Sign

Recruiting

• Conditions: Anterior Cruciate Ligament Injuries; Anterior Cruciate Ligament Rupture; Anterior Cruciate Ligament Tear
• Interventions: Diagnostic Test: Measurements on knee MRI performed during routine clinical practice

• Registration Number: NCT05682820
• Lead Sponsor: Artromedical Konrad Malinowski Clinic

Brief Summary

Analysis of Radiological Features of Lateral Femoral Impaction Fracture (LFC-IF) / Lateral Femoral Notch Sign will be performed on MRIs of consecutive patients after anterior cruciate ligament (ACL) injuries and without ACL injuries.

Detailed Description

Two independent measurers will twicely measure the radiological features of Lateral Femoral Impaction Fracture / Lateral Femoral Notch Sign on MRIs of consecutive patients after anterior cruciate ligament (ACL) injuries and without ACL injuries. In cases without ACL injuries, radiological features of terminal sulcus (TS), a native sulcus located on the lateral femoral condyle, will be measured. Intra- and inter-rater agreements will be calculated.

The following radiological features will be assessed/ measured:

1. Presence of LFC-IF/ TS

2. LFC-IF/ TS depth

3. LFC-IF/ TS length

4. Distance from Blumensaat line to the front border of LFC-IF / TS

5. Distance from Blumensaat line to the deepest part of LFC-IF / TS

6. Distance from Blumensaat line to the rear border of LFC-IF / TS
