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]

Contents

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 valgus deformity. Surgical repair of the ligament often leads to better outcomes than conservative management. [4]

The oblique popliteal ligament may be cut during arthroscopic meniscus repair surgery. [5]
