•This figure illustrates the intimate relationship of the static and dynamic structures of the posteromedial corner, including the semimembranosus tendon fascial expansion that attached directly to the posterior horn of the medial meniscus.
•TThe medial meniscal posterior meniscocapsular junction is composed of the meniscocapsular ligament superiorly (also known as meniscosynovial or synovial membrane ligaments) and the meniscotibial ligament inferiorly, both of which attach peripherally into the posterior horn of the medial meniscus.
•The attachment of the MM to the joint capsule is more rigid, making the MM more susceptible to injury than the LM.
•The PHMM had a mean length of 21.3 ± 2.0 mm (range, 17.6-24.5 mm), essentially confluent with the entire length of the posterior capsule.
•The posterior #meniscocapsular attachment had a mean ± SD length of 20.2 ± 6.0 mm (range, 11.3-33.2 mm)
The semimembranosus-meniscal attachment branched from the anterior arm of the semimembranosus and was located between the posterior meniscotibial ligament and the #meniscotibial POL attachments
