Erect positions for "tunnel" views of the knee.
Two erect methods of radiographing the knee to produce tunnel views of the joint space are presented. Each method produces an excellent image of the intercondyloid fossa without distortion seen with some previous methods. Both erect methods are simple to perform and appear to be more comfortable for patients.
