Meniscocapsular Ligament

Description

Meniscocapsular ligaments

Posterior medial meniscus anatomy, with its corresponding structures. In (a), an illustrated open view of the medial compartment of the knee, in (b), a zoomed view of the posteromedial capsular-meniscal unit, and in (c), the corresponding MRI appearance on sagittal PD-weighted fat suppressed: meniscocapsular ligament (thin arrow), meniscotibial ligament (curved arrow) and posterior capsular attachment (star)

Name

• Meniscocapsular Ligament

Gross Anatomy

• Collagenous structure of the posteromedial corner of the knee
• Close anatomic relationship with the meniscotibial ligament
• Fibers merge with the capsular arm of the semimembranosus tendon

MRI Features

• Best seen in sagittal plane as a thin, hypointense structure
