Lateral collateral ligament of the knee
Updates to Article Attributes
The lateral (fibular) collateral ligament is a cord-like ligament on the lateral aspect of the knee and forms part of the posterolateral corner. The lateral aspect of the knee is divided into 3 layers. It is part of the deep layer of the lateral aspect of the knee.
Gross anatomy
The lateral collateral ligament's average length is 70mm.
It originates slightly posterior (3mm) within an osseous depression from the lateral femoral epicondyle and inserts at the head of the fibula.
Unlike the medial collateral ligament, it is not attached to the knee capsule or lateral meniscus and as such, is more flexible and less susceptible to injury 1.
Relations
The tendon of the popliteus (through the popliteal hiatus), a bursa and the lateral inferior geniculate vessels and nerve run deep to the lateral collateral ligament. IliotibialThe iliotibial band is superficalsuperficial to LCL andthe lateral collateral ligament and attaches to the Gerdy's tuberletubercle.
Innervation
3 distinct innervation:branch of tibial nerve , branch from common fibular nerve from the popliteal fossa and another branch of the common fibular nerve at the head of the fibula.
Blood Supply
Inferior lateral genicular artery and anterior tibial recurrent artery.
