Blumensaat's line

Blumensaat's line is a line which corresponds to the roof of the intercondylar fossa of femur as seen on a lateral radiograph of the knee joint.[1] The angle at which this line appears on the radiograph can be used to determine the position of the patella or diagnose an ACL injury.[2]

Clinical Use

On a normal radiograph, the line intersects the inferior pole of the patella, and so can be useful in diagnosing a broken femur as well as a patellar tendon rupture.
