Sunrise view  
 

The sunrise view is a tangential look at the flexed knee. The patient is positioned so that the long axis of the patella is parallel to the x-ray beam, perpendicular to the film cassette/detector. This view is used to assess the patellofemoral articulation, which may be altered by degenerative joint disease.

The femur and tibia are superimposed. Typically the medial femoral condyle is more rounded and/or prominent than the lateral femoral condyle.
