The arcuate popliteal ligament is an Y-shaped extracapsular ligament of the knee.^[1]^[2]^: 138 It is formed as a thickening of the posterior fibres of the joint capsule of the knee.^[2]^: 138 It reinforces the knee joint capsule inferolaterally.^[3]

Anatomy

From its fibular attachment, the ligament extends superomedially over the tendon of the popliteus muscle, spreading out^[3] superficial to the posterior aspect of the tendon.^[3]^[2]^: 134

Attachments

Its inferior attachment is at the posterior aspect of the head of the fibula.^[1]^[2]^: 138^[3]

It has two superior attachments:

The medial part of the ligament extends superficial to the tendon of popliteus muscle^[2]^: 138 to attach at the posterior part of the intercondylar area of tibia.^[3]^[2]^: 138
The lateral part forms a separate band that extends to the posterior part of^[3] the lateral condyle of femur^[3]^[2]^: 138 alongside the tendon of popliteus muscle.^[2]^: 138
