Proper Use of MR Imaging in Internal Derangement of the Knee (Orthopedic Surgeon's View)

ABSTRACT

MR imaging of the knee is a highly accurate examination in terms of the detection of meniscal tears and cruciate ligament ruptures among internal derangement of the knee. The overall accuracy in more than two thousand published cases reached nearly as high as 90% in meniscal tears, and 94% in anterior cruciate ligament (ACL) and 99% in posterior cruciate ligament (PCL) ruptures. Furthermore, the negative predictive value of the knee MR imaging, the number of true negative examination results divided by the numbers of true negative plus false-negative examination results, reaches almost 100% because of its very low false-negative rate. Therefore, from the orthopaedic surgeon's point of view, even though the medical cost becomes a great concern ever than before, MR imaging has prime importance in the diagnosis of the internal derangement of the knee.
