📌 Significance of Radial Tears:
• Unlike horizontal and longitudinal tears, radial tears significantly disrupt meniscal hoop strength.
• The deeper the tear, the more it impacts the biomechanical function of the menisci.
🔬 Radiologic Signs to Detect Radial Tears:
1. Truncated Triangle Sign:
• Truncation of the free edge, usually indicating a partial-thickness tear.
2. Ghost Meniscus Sign:
• High signal in place of the normally low signal posterior horn, suggesting a full-thickness tear.
3. Cleft Sign:
• Can indicate both longitudinal and radial tears, depending on the tear’s location relative to the imaging plane.
4. Marching Cleft Sign:
• Appears as a progressing cleft away from the free edge on contiguous MR imaging sections, especially at the junction of the horn and body.
