The Rosenberg View

diagram showing technique for obtaining the Rosenberg view.

The maximum stresses in the knee joint occur between 30 and 60 degrees of flexion; therefore, standard anteroposterior weight-bearing radiographs on extension are not ideal for evaluation of cartilage loss as indicated by joint space narrowing. The Rosenberg view was created to address this issue.

The Rosenberg view is a 45-degree flexion, posteroanterior, weight-bearing view of the knee with the patellae touching the image receptor. The x-ray tube is 40 inches (101.6 cm) away from the image receptor, centered at the patellae, and pointing caudad 10 degrees.

The Rosenberg view is more sensitive and specific for joint space narrowing than the conventional extension weight-bearing anteroposterior views, and is useful for the assessment of knees with early degenerative change.
