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.
Gross anatomy
It originates from the lateral femoral epicondyle and has an oblique course, is joined by the biceps femoris tendon forming the conjoint tendon, which 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. Iliotibial band is superfical to LCL and attaches to the Gerdy's tuberle.
Nerve and Blood Supply
Common fibular nerve primarily innervates LCL. Blood supply is from inferior and lateral genicular arteries branches of popliteal artery.
