Meniscotibial ligaments

Last revised by Henry Knipe on 16 Nov 2021

The meniscotibial ligaments, also known as coronary ligaments, attach the knee menisci to the tibial plateau 1-6 and have a role in rotatory knee stability and anterior tibial translation 7-10.

The meniscotibial ligaments attach the menisci to the tibial condyles at various locations apart from the meniscal root attachments 1-4.   

The medial meniscus is attached to the medial tibial condyle at the following locations 1-3:

  • posterior horn via the posterior meniscotibial ligament 1
  • midportion or corpus via the meniscotibial portion of the deep medial collateral ligament 2,3

The meniscotibial ligaments originate immediately inferior (6-7 mm) to the edge of the articular cartilage of the medial and posterior part of the medial tibial plateau and insert at the outer surface of the medial meniscus just above the inferior edge. The medial posterior meniscotibial ligament attaches immediately inferior to the meniscocapsular ligament 1,11.

Additional attachments are located posteromedially via the following structures 1,12:

The lateral meniscus is attached to the lateral tibial condyle at the following locations 4-6:

  • posterior horn via the posterior meniscotibial ligament 4
  • midportion or corpus via the lateral meniscotibial ligament, which courses obliquely immediately beneath the fibular collateral ligament 5,6

There are additional attachments of the lateral meniscus to the popliteus muscle posterolaterally via the popliteomeniscal fascicles 4 and to the joint capsule at its superior border 4 as well as to the fibula by the meniscofibular ligament 5.

The medial posterior meniscotibial ligament is located medially and posteriorly to the medial meniscal root attachment 1 and covered by the joint capsule, which forms its tibial insertion inferiorly to the origin of the meniscotibial ligament 1. The meniscotibial attachment of the deep medial collateral ligament is covered by its superficial portion 2,3.

The lateral posterior meniscotibial ligament is located laterally and posteriorly to the lateral meniscal root attachment and medially to the popliteal hiatus a curved gap with a lack of inferior ligamentous attachments 4.

The coronary ligaments are visible in MRI as thin hypointense structures.
