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.
Injuries to the PLC often occur in combination with other ligamentous injuries to the knee; most commonly the anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL). [2] As with any injury , an understanding of the anatomy and functional interactions of the posterolateral corner is important to diagnosing and treating the injury.
The oblique popliteal ligament is a radiation of the tendon of the semimembranosus on the medial side, from where it is direct laterally and proximally. The arcuate popliteal ligament originates on the apex of the head of the fibula to stretch proximally, crosses the tendon of the popliteus muscle, and passes into the capsule. [10]: 206
It extends from the lower margin of the patella above, to the infrapatellar synovial fold below. With its free upper margin, this fold extends dorsally through the joint space to surround the two cruciate ligaments from the front, thus dividing the surrounding joint space into two chambers. Laterally of this are a pair of alar folds. [2]
The lateral tarsal artery (tarsal artery) arises from the dorsalis pedis, as that vessel crosses the navicular bone; it passes in an arched direction lateralward, lying upon the tarsal bones, and covered by extensor hallucis brevis and extensor digitorum brevis; it supplies these muscles and the articulations of the tarsus, and receives the arcuate over the base of the fifth metatarsal.
The arcuate ligament may refer to: Inferior pubic ligament (arcuate ligament of the pubis). Arcuate popliteal ligament. Arcuate ligaments of the diaphragm: Median arcuate ligament; Medial arcuate ligament; Lateral arcuate ligament
The lateral meniscus is grooved laterally for the tendon of the popliteus, which separates it from the fibular collateral ligament.. Its anterior end is attached in front of the intercondyloid eminence of the tibia, lateral to, and behind, the anterior cruciate ligament, with which it blends; the posterior end is attached behind the intercondyloid eminence of the tibia and in front of the ...
