title: The patellofemoral joint: 30 degrees, 60 degrees, and 90 degrees views.
abstract: In 70 patients evaluated for abnormality of the patellofemoral (PF) joint, axial radiographs at 30 degrees, 60 degrees (Ficat views) were obtained, with positive studies in 19. The examination technique and the interpretation of the Ficat views are discussed. In selected patients, the examination can yield valuable information not obtainable by other methods about the PF articulation, allowing differentiation of numerous patellar abnormalities from a torn meniscus. Its value in arthrography is also discussed, as well as its usefulness in evaluating chondromalacia and recurrent patellar subluxation.
