The Arcuate popliteal ligament (Ligamentum popliteum arcuatum) is a thick and broad fibrous band located in the knee joint. It is one of the important ligaments that provide stability to the knee joint.
Anatomy[edit | edit source]
The arcuate popliteal ligament originates from the apex of the head of the fibula and extends upwards and medially, crossing the posterior aspect of the knee joint. It then attaches to the intercondylar area of the tibia and the posterior part of the joint capsule.
Function[edit | edit source]
The arcuate popliteal ligament plays a crucial role in maintaining the stability of the knee joint. It prevents excessive movement and helps in the smooth functioning of the knee joint.
Clinical significance[edit | edit source]
Injury to the arcuate popliteal ligament can lead to instability of the knee joint, causing pain and difficulty in movement. Treatment usually involves rest, physiotherapy, and in severe cases, surgery may be required.
