Is a magnetic resonance imaging scan necessary to diagnose knee arthritis?

摘要

Regarding the article "The Accuracy of Magnetic Resonance Imaging Scanning and Its Influence on Management Decisions in Knee Surgery" by Galea et al., which was published in the May 2009 issue, the elephant in the middle of the room is whether the patients ever really needed magnetic resonance imaging to detect their arthritis. Patients in this study underwent the following radiographs: "weight-bearing anteroposte-rior, lateral, and skyline." With a standing-flexion posteroante-rior view (Rosenberg, schuss), femorotibial arthritis would often have been detected without the need for magnetic resonance imaging.
