The ligament of Wrisberg is in the knee. It runs from the medial femoral condyle behind the posterior cruciate ligament to the posterior horn of the lateral meniscus. If the ligament runs in front of the posterior cruciate ligament, it is a ligament of Humphries.

The spring ligament supports the medial longitudinal arch.

You have posterior longitudinal ligament on the back side of the body of the vertebrae and discs. So there is herniation of the nucleus pulposus, coming out of the tear in the annulus fibrosus.

Four ligaments are present in the knee joint, the medial collateral ligament, lateral collateral ligament, anterior cruciate ligament, and posterior cruciate ligament. The medial collateral ligament is located at the inside of the knee joint. It extends from the medial femoral epicondyle to the tibia. The lateral collateral ligament is located at the outside of the knee joint. It extends from the lateral femoral epicondyle to the head of the fibula. The anterior cruciate ligament extends posterolaterally from the tibia and inserts on the lateral femoral condyle. The posterior cruciate ligament extends anteromedially from the tibia posterior to the medial femoral condyle.

Yes, it's full name is the "posterior meniscofemoral ligament".
