Anatomical terminology |
The lateral collateral ligament (LCL, long external lateral ligament or fibular collateral ligament) is an extrinsic ligament of the knee located on the lateral side of the knee.[1][verification needed][2] Its superior attachment is at the lateral epicondyle of the femur (superoposterior to the popliteal groove); its inferior attachment is at the lateral aspect of the head of fibula (anterior to the apex). The LCL is not fused with the joint capsule. Inferiorly, the LCL splits the tendon of insertion of the biceps femoris muscle.[2]
