Clinical Trial 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.

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
