The oblique popliteal ligament (posterior ligament) is a broad, flat, fibrous ligament on the posterior knee.{{cite journal |last1=Mehta |first1=V |last2=Dawani |first2=P |last3=Goel |first3=P |title=Morphologic and Morphometric Evaluation of Oblique Popliteal Ligament - A Clinico-Anatomical Study. |journal=Maedica |date=September 2022 |volume=17 |issue=3 |pages=641–646 |doi=10.26574/maedica.2022.17.3.641 |pmid=36540577|pmc=9720660 }} It is an extension of the tendon of the semimembranosus muscle.

Anatomy
The oblique popliteal ligament is formed as a lateral expansion of the tendon of the semimembranosus muscle and represents one of the muscle's five insertions.{{Citation needed|date=November 2022}} The ligament blends with the posterior portion of the knee joint capsule. It exhibits a large opening through which nerves and vessels pass.

The ligament extends superolaterally from the semimembranosus tendon to attach onto the intercondylar fossa and lateral condyle of the femur.

The oblique popliteal ligament forms part of the floor of the popliteal fossa;{{Citation needed|date=November 2022}} the popliteal artery lies upon the ligament. 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|date=November 2022}}
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.{{Citation |last1=Berkson |first1=Eric M. |date=2016-01-01 |url=https://www.sciencedirect.com/science/article/pii/B9780323310727000208 |work=Pathology and Intervention in Musculoskeletal Rehabilitation (Second Edition) |pages=713–773 |editor-last=Magee |editor-first=David J. |publisher=W.B.
