Patellofemoral joint: 30 degrees axial radiograph with lateral rotation of the leg.
A method for axial radiography of the patellofemoral joint has been developed that combines a forced lateral rotation of the leg with 30 degrees flexion of the knee. This view can be obtained without any special device and is definitely superior to the 45 degrees routine axial view in the detection of lateral subluxation of the patella. It should be obtained when patellar instability is suspected.
