Posterior oblique ligament of the knee
The posterior oblique ligament (POL) belongs to the medial supporting structures of the knee and is one of the five components of the posteromedial corner (PMC) of the knee.
Gross anatomy
It is located posterior to the medial collateral ligament (MCL) and it is composed of the intermediate and deep medial capsular layer .
Attachments
The femoral attachment originates just distal and posterior to the adductor tubercle .
Its distal attachment consists of three components: a superficial, central and capsular extension :
- the superficial extension attaches to the proximal tibia together with the distal insertion of the semimembranosus tendon and blends anteriorly with the posterior part of the medial collateral ligament
- the central extension is the most prominent part and attaches to the posteromedial part of the medial meniscus
- the capsular extension blends into the posteromedial joint capsule and fuses with the capsular insertion of the semimembranosus tendon as well as the medial part of the oblique popliteal ligament
