posteromedial

Posteromedial is an anatomical directional term used to describe a location that is both posterior (toward the back) and medial (toward the midline) relative to a reference point. It is used across anatomy, radiology, and surgical planning to specify where a structure lies or where pathology is located.

In the knee, the term often refers to the inner-back region of the joint. The posteromedial aspect can denote areas such as the posteromedial corner of the knee and the posteromedial tibial plateau; injuries and pathologies in this region include posteromedial meniscal root tears and posteromedial tibial plateau fractures, which influence stability and treatment strategies.

In the orbit, the posteromedial wall refers to the back and inner portion of the orbital bony boundary; fractures involving this area are described as posteromedial orbital wall fractures and may affect the orbital contents and sinus relationships.

Commonly used in other joints and surfaces as well, the term simply locates a structure or lesion in relation to the posterior aspect and the midline. Etymology derives from Latin posterior (behind) and medialis (toward the midline).
