📌 Grading MCL Injuries on MRI
- Injury Patterns Injuries to the medial collateral ligament (MCL) of the knee are extremely common, often resulting from valgus loading forces.
- While proximal ruptures are more frequent, any combination of injury locations can occur.
✅MRI Grading System
Radiologists typically grade MCL injuries on MRI using a three-tier system, despite its better applicability to clinical assessment.
- Grade 1 denotes edema around an intact MCL,
- grade 2 indicates ligamentous attenuation and thickening, and
- grade 3 signifies complete discontinuity.
✅ Discrepancies with Clinical Grading
- However, there is only fair agreement between MRI and clinical grading, with MRI tending to overestimate injury severity when discrepancies exist.
- Although the three MRI grades aim to reflect injury extent, they frequently diverge from the clinical picture.
