Abstract:
BACKGROUND:Conventional imaging method has significant limitations in the diagnosis of knee meniscus injury, which is difficult to detect the ful extent of the knee meniscus. OBJECTIVE:To evaluate the knee meniscus injury with magnetic resonance imaging. METHODS:The knee meniscus injury patients diagnosed with clinical treatment were retrospectively analyzed, and the characteristics of the magnetic resonance imaging were analyzed and graded. Then, the meniscus injury was analyzed and compared with the arthroscopic or surgical results. RESUTLS AND CONCLUSION:In the magnetic resonance imaging of knee meniscus injury, the Ⅰ level knee meniscus injury was presented as the punctate or round high signal that did not contacted with the surface of the meniscus, Ⅱ level knee meniscus injury was presented as the horizontal or oblique line or strip-like high signal in the meniscus, and Ⅲ level knee meniscus injury was presented as lines and complex high signal in the meniscus that extended to the articular surface of the meniscus, and accompanied with morphological changes of the meniscus. Magnetic resonance imaging, as a noninvasive checking method, can clearly show the meniscal degeneration and tearing, and correctly diagnosed the location, shape and severity of meniscus injury, which has significant guiding value in determine the clinical treatment options.
