There are several kinds of diagnostic methods to evaluate internal derangement of the nee joint. Among them magnetic resonance imaging(MRI0 is a noninvasive diagnostic method for evaluation of soft tissue pathology such as meniscus and cruciate
ligaments intry.
From May, 1993 to August, 1995 MRI and arthroscopy were performed in 68 cases of inernal derangement of the knee, and their result were retrospectively analyzed to determines diagonstic accuracy.
There were 52 menisic and 34 cruciate ligaments injuries were confirmed by arthroscopic examination. The sensivity, specificity and accuracy of MRI were 89.9%, 50.0%, 70.6% for ?edial meniscus, 78.8%, 84.25, 79.4% for lateral meniscus, 77.8%,
96.0%,
91.2% for anterior uciate ligament, and 93.3%, 100%, 98.5% for posterior cruciate ligament.
Authors believe that MRI is not only accurate, safe, and noninvasive diagnostic method it also an excellent diagnostic procedure for evaluation of the efficient preoperative planning the internal derangement of the knee such as the pathological
findings
in meniscus an ?uciate ligament.
