PDFAbstract
Objective To investigate the diagnostic value of CT and MRI in patients with different stages of knee meniscus and articular cartilage injury. Methods A total of 68 patients with knee meniscus and articular cartilage injury treated in our hospital from January 2016 to May 2018 were selected and underwent CT and MRI examination. The examination results were compared with those of knee arthroscopy as golden standard. Then the diagnostic accuracy of CT and MRI was compared. Results The diagnosis rate of knee meniscus was 93.85% for MRI and 81.35% for CT. The diagnosis accuracy rate in grade I and grade II had no difference (P>0.05), while the diagnosis accuracy rate in stage III of the MRI was higher than that of the CT (P<0.05). The diagnostic rate of articular cartilage injury was 96.61% for MRI and 83.05% for CT. The diagnostic accuracy among the stage of I, IIa, IIb and III had no difference (P>0.05). The diagnostic rate for stage IV of MRI was significantly higher than that of CT (91.67% vs75%, P<0.05). Conclusion The diagnostic accuracy rate for knee meniscus and III articular cartilage injury of MRI was higher than that of the CT, and the diagnosis rate of two examinations is similar for the rest types.
