Anatomical terminology |
The oblique popliteal ligament (posterior ligament) is a broad, flat, fibrous ligament on the posterior knee.[1] It is an extension of the tendon of the semimembranosus muscle.[1][2] It attaches onto the intercondylar fossa and lateral condyle of the femur.[2] It reinforces the posterior central portion of the knee joint capsule.[3]
Anatomy
The oblique popliteal ligament is formed as a lateral expansion of the tendon of the semimembranosus muscle[2] and represents one of the muscle's five insertions.[citation needed] The ligament blends with the posterior portion of the knee joint capsule.[2] It exhibits a large opening through which nerves and vessels pass.[3]
Attachments
The ligament extends superolaterally from the semimembranosus tendon to attach onto the intercondylar fossa and lateral condyle of the femur.[2][3]
Relations
The oblique popliteal ligament forms part of the floor of the popliteal fossa;[citation needed] the popliteal artery lies upon the ligament.[2] The ligament is pierced by posterior division of the obturator nerve, as well as the middle genicular nerve, the middle genicular artery, and the middle genicular vein.[citation needed]
Clinical significance
The oblique popliteal ligament may be damaged, causing a
The oblique popliteal ligament may be cut during arthroscopic meniscus repair surgery.[5]
