What does the ligament of Wrisberg do?

There are two meniscofemoral ligaments: the anterior meniscofemoral ligament (aMFL), also known as the ligament of Humphrey, and the pMFL, also known as the ligament of Wrisberg. The meniscofemoral ligaments connect the posterior horn of the lateral meniscus to the lateral side of the medial femoral condyle.

Who are Humphrey and Wrisberg?

The anterior meniscofemoral ligament (aMFL) which is leaning anterior to the posterior cruciate ligament (PCL) is also known as ligament of Humphrey, and the posterior meniscofemoral ligament (pMFL) leaning posterior to PCL is known as ligament of Wrisberg [1–6].

What is a Wrisberg rip?

Wrisberg rips, also known as zip tears or zipper tears, are longitudinal vertical meniscal tears. They occur at the junction of the ligament of Wrisberg and the posterior horn of the lateral meniscus and are commonly associated with anterior cruciate ligament tears 1.

What is the ligament of Humphrey?

The anterior meniscofemoral ligament (ligament of Humphry) is a small fibrous band of the knee joint. It arises from the posterior horn of the lateral meniscus and passes superiorly and medially in front of the posterior cruciate ligament to attach to the lateral surface of medial condyle of the femur.

Is the Wrisberg ligament anterior to the PCL?

The Ligament of Wrisberg is the more common of the meniscofemoral ligaments 1, and courses posterior to the PCL (2a) as it descends to the posterior horn of the lateral meniscus. Less commonly, a Ligament of Humphrey is present, in which case the ligament runs anterior to the PCL.

Where are the ligaments of Humphrey and Wrisberg located?

– the ligaments of Humphrey and Wrisberg are meniscofemoral ligaments which run from the posterior horn of the lateral meniscus to the lateral aspect of the medial femoral condyle; – these ligaments are named based on their location in relation to the PCL;

Is the ligament of Humphrey anterior to the PCL?

Less commonly, a Ligament of Humphrey is present, in which case the ligament runs anterior to the PCL.

Where does the pseudotear of the Wrisberg occur?

If you answered “no tear”, it’s likely because you are aware of the well-known Ligament of Wrisberg pseudo-tear 2, caused by the vertical/oblique signal intensity region (3a) that occurs normally at the junction of the Ligament of Wrisberg with the posterior horn of the lateral meniscus.
