📌 Injury to the Oblique Popliteal Ligament
- Injury is usually best seen on axial and sagittal planes
- Difficult to visualize the intact ligament directly
- Inferred from injury to the posterior joint capsule
- Signs include irregularity, thickening, disruption of the posterior capsule/OPL and surrounding edema
- Edema and irregularity of the posteromedial joint capsule suggesting high-grade oblique popliteal ligament tear
- Disruption of the posterior joint capsule implying at least partial oblique popliteal ligament tear
✅ Mechanism of Injury: Pure Hyperextension
- May injure soft tissues around the posterocentral knee
- Both posteromedial and posterolateral corners can be affected
- Central injuries can involve the posterior capsule and PCL with severe hyperextension
- Concomitant ACL injury sometimes observed
