1. Radial tear sparing the MFL attachment without displacement
- Radial tears that spare the meniscofemoral ligament attachment typically occur near where the meniscofemoral ligaments attach to the meniscus.
- These intact ligaments help stabilize the lateral meniscus, preventing its extrusion.
2. LM Posterior Root Tear. Association with ACL Tears
- In patients with ACL tears, there is a higher incidence of lateral meniscal root tears (8%) compared to those without ACL tears (0.8%).
- This suggests the need for careful MRI examination of the lateral meniscus in cases of ACL injury.
3. Treatment Approaches
- - Some surgeons opt for non-surgical treatment for small, stable posterior root tears of the lateral meniscus.
- - Others advocate for repair, especially noting that a lateral meniscus posterior root tear, when accompanied by an ACL tear, can lead to significant biomechanical changes like increased anterior tibial translation, even if the meniscofemoral ligament is intact.
