The Coronary ligaments of the [[knee]] or '''meniscotibial ligaments''' are part of the fibrous capsule of the knee joint. There are two coronary ligaments namely medial coronary ligament and lateral coronary ligament. They connect the inferior edges of the meniscus to the periphery of the tibial plateaus. The meniscotibial ligament solidly anchors the posterior horn of the medial meniscus.

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]. They can also cause increased strain on the anterior cruciate ligament or menisci[5][6] . This leads to risk of meniscal extrusion or other injury to these structures[7]. 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[8]:

  • 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.


Swelling is not common in these injuries.

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]

Knee physio.jpg

Treatment will vary according to the injury, the severity and if other structures have been affected.

First line treatment for coronary ligaments includes RICE, medicines such as painkillers or anti-inflammatories and physiotherapy[8]. Physiotherapy will be tailored to improving biomechanics and strengthen the surrounding muscles, especially the quadriceps.

Surgery may be required if the injury is severe, to promote stability of the knee, or in order to protect other structures from further strain[3]. One study found repair of medial coronary ligaments reduced meniscal extrusion, which may improve meniscal function and reduce the risk for osteoarthritis[9].
