Description[edit | edit source]
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.
The meniscotibial ligament is thicker and shorter. It travels from the medial meniscus to the distal edge of the articular cartilage of the medial tibial plateau. The lateral meniscotibial ligament attaches to the lateral face of the lateral meniscus and descended oblique dorsally to reach the superolateral margin of the lateral tibial condyle.
Function[edit | edit source]
The coronary ligaments function to stabilize the menisci and limit rotation of the knee.
Clinical relevance[edit | edit source]
Meniscotibial ligament strain is a common cause of knee pain in middle-aged sportspeople. Coronary ligament injuries may occur either as a rupture in its mid-substance or as an avulsion. In a study by Peltier et al they concluded that lesions of the meniscotibial ligament may increase rotatory instability of the knee. Injury to the meniscotibial ligament attachment of the posterior horn of the medial meniscus is suggested by recent literature to be associated with ramp lesions. Ramp lesions are reported to increase forces on the anterior cruciate ligament,. 
Assessment[edit | edit source]
it's useful to test any meniscal damages using McMurray test
Treatment[edit | edit source]
Treatment will vary according to the injury, its degree and whether any other structures have been affected as well .
