Background
Knee pain is a common clinical complaint. Given the complex anatomy of the posteromedial knee, musculoskeletal pathology of this region can be easily overlooked. Therefore, knowledge of pertinent anatomy and key pathologic imaging features is paramount for accurate diagnosis. This in turn provides for appropriate and timely management - a crucial factor particularly in posteromedial knee injuries predisposing to anteromedial rotational instability.

Educational Goals / Teaching Points
This educational exhibit will provide a targeted review of normal medial knee anatomy and various pathologic conditions resulting in posteromedial knee pain. Emphasis will be on magnetic resonance imaging (MRI) with inclusion of some important features seen on other imaging modalities. Our goal is to provide a concise compilation of key imaging features to strengthen confident diagnosis of these conditions. Important management implications are also included as appropriate.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
The pathology-specific anatomy of the medial knee will be reviewed, and then unique imaging characteristics of a variety of knee conditions resulting in posteromedial knee pain will be described with an emphasis on MRI. These are to include posteromedial friction syndrome, traumatic ligamentous injuries, medial collateral ligament bursitis, semimembranosus bursitis, pes anserinus bursitis, and menisco-osseous impingement.

Conclusion
While the complexity of the posteromedial knee may be deterring, accurate diagnosis of pathology within this region remains essential for appropriate patient care. Given the directed review provided by this exhibit, the participant will come away with increased confidence and understanding for providing future assessment of pathology within this region
