Imaging of the knee

David A. Rubin, Mario Maas

Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review


Conventional radiographs are the initial imaging study in most suspected knee disorders. A minimum radiographic examination consists of an anteroposterior (AP) and lateral projection. For the early detection of articular cartilage loss, a posteroanterior (PA) radiograph of both knees with the patient standing and knees mildly flexed (the Rosenberg projection) is a useful adjunct: a joint space difference of 2 mm side-to-side correlates with grade III and higher chondrosis [1]. In patients with anterior knee symptoms, an axial projection of the patellofemoral joint, such as a Merchant view, can evaluate the patellofemoral joint space and alignment [2].
