Description[edit | edit source]

The coronary ligaments, also known as the meniscotibial ligaments, are part of the fibrous capsule of the knee joint. They are made up of the medial coronary ligament and the lateral coronary ligament. They connect the inferior edges of the menisci to the of the tibial plateau[1].

Function[edit | edit source]

The coronary ligaments support rotational stability of the knee and prevent anterior tibial translation[2].

Clinical relevance[edit | edit source]

Coronary ligament injuries can lead to other knee joint pathology and negatively alter the biomechanics of the knee[3]. Lesions to the coronary ligaments can increase rotational instability[4]. Moreover, an injury to these ligaments can lead to increased strain on the anterior cruciate ligament or menisci, increasing the risk of injury to these structures[5][6] . Research suggests coronary ligament injuries are under diagnosed and untreated, as they present similar to meniscus pathologies[3].

Assessment[edit | edit source]

Common signs and symptoms of coronary ligament injury include[7]:

  • Tenderness along the lateral and medial aspects of the knee joint line.
  • Feeling of instability.
  • Sharp pain during knee flexion or rotational movements.
  • Usually have full range of motion but feel discomfort at end of the range flexion and extension.


After getting a thorough history, the physical examination should include:


If required, MRI scans can be used to confirm the diagnosis.

Treatment[edit | edit source]

Treatment will vary according to the injury, its degree and whether any other structures have been affected as well .
