The Rosenberg view is a weight-bearing X-ray view with the knees bent at 45 degrees, and which is sensitive in terms of looking for early osteoarthritis of the knee and joint space narrowing.

rosenberg view
If the meniscus and/or articular cartilage are deficient on one side, the weight going through the joint will decrease the gap between tibia and femur on that side. This may not be evident in a non-weight-bearing film.


Advantages of the Rosenberg View

For the Rosenberg view, the patient stands with the knees bent to 45 degrees against the X-ray plate, while the X-ray machine is behind the knee at an angle slightly downwards (45° flexion PA weight-bearing view).

What will the radiologist be looking for?

This X-ray view may offer information about narrowing of the normal joint space which is not available in a straight-leg X-ray. There may also be evidence of bone spurs and cysts, and irregular bone density.
