MRI of the Knee

This issue of Magnetic Resonance Imaging Clinics of North America focuses on the knee. Kirkland Davis, a Professor of Radiology and Section Chief in Musculoskeletal Imaging at the University of Wisconsin, has done a fantastic job of assembling some of the most accomplished North American musculoskeletal radiologists for this project. The esteemed authors are from highly regarded institutions that specialize in musculoskeletal MRI. State-of-the-art material is presented on important subjects with excellent figures, diagrams, and up-to-date references enhancing learning for even the most experienced radiologist. Although many of us feel comfortable reading knee MRIs, it is helpful to keep up with all of the new information regarding anatomy and pathology. The menisci, ligaments, and tendons along with the patellofemoral joint can be challenging to assess. When radiologists understand biomechanics, they become more adept at knowing what abnormalities to look for in the study. More and more we are imaging postoperative knees, and it is important to know about the surgery and what to expect after surgery along with the best way to image when there is metal in the mix. The cartilage is a very important structure to evaluate, and there are many different sequences that we can use for this assessment. We need to be accurate in our descriptions of cartilage abnormalities and postoperative cartilage assessment because cartilage repair is frequently performed. A volume such as this makes us more able to master this subject during our readouts. Bravo for a job well done!
