📌 Meniscofemoral Ligament Tear

✅ Associations and Implications

• Associated with high-grade MCL injuries, meniscocapsular separation, and meniscal injuries
• In ACL-deficient knee, sMCL and medial capsule act as secondary restraints to anterior tibial translation
• Meniscofemoral ligament injuries are prevalent in ACL ruptures and can present with clinically normal medial ligamentous laxity
• Significantly associated with posterior horn medial meniscal tears, a potential risk factor for ACL graft failure

 

✅ Avulsion Injury of The deep medial meniscofemoral ligament

• The deep medial meniscofemoral ligament has a direct attachment to the femur
• Marrow edema at the attachment site is related to an avulsion injury
  (➡️ Medial femoral condyle bone marrow edema at the meniscofemoral ligament insertion site should raise suspicion of injury)
• Ligament fibers extend into bone at right angles for direct attachment
