Abstract
The posteromedial corner (PMC) of the knee is an anatomical region formed by ligamentous structures (medial collateral ligament, posterior oblique ligament, oblique popliteal ligament), the semimembranosus tendon and its expansions, the posteromedial joint capsule, and the posterior horn of the medial meniscus. Injuries to the structures of the PMC frequently occur in acute knee trauma in association with other ligamentous or meniscal tears. The correct assessment of PMC injuries is crucial because the deficiency of these supporting structures can lead to anteromedial rotation instability or the failure of cruciate ligaments grafts. This article reviews the anatomy and biomechanics of the PMC to aid radiologists in identifying injuries potentially involving PMC components.
期刊介绍：
Seminars in Musculoskeletal Radiology is a review journal that is devoted to musculoskeletal and associated imaging techniques. The journal''s topical issues encompass a broad spectrum of radiological imaging including body MRI imaging, cross sectional radiology, ultrasound and biomechanics. The journal also covers advanced imaging techniques of metabolic bone disease and other areas like the foot and ankle, wrist, spine and other extremities.
The journal''s content is suitable for both the practicing radiologist as well as residents in training.
