Abstract Objective To explore the diagnostic value of MRI examination on cartilage injury of patellofemoral arthritis.Methods From March 2015 to September 2017,the MRI imaging data of 67 cases of patellofemoral arthritis who hospitalized in the department of orthopedics in our hospital were analyzed,retrospectively.The MRI examination included the FS-FSE-T2W sequence and the 3D-FS-SPGR sequence.The MRI examination results was compared with the results of arthroscopy.Results Among the 67 patients,36 cases were cartilage injury in the medial margin of the patella,31 cases were cartilage injury in the anterolateral border of the lateral condyle of the femur.MRI examination showed that 27 cases were abnormal cartilage and signal in the medial margin of the patella,21 cases showed abnormal cartilage injury in the anterolateral border of the lateral condyle of the femur,6 cases showed thinning of cartilage,and 13 cases showed significant interruption or defect of local cartilage.The sensitivity and specificity of FS-FSE-T2W sequence for cartilage injury were 83.65%and 96.27%,respectively,and the sensitivity and specificity of 3D-FS-SPGR sequence were 93.67%and 99.18%,respectively,the differences were statistically significant(P＜0.05).Conclusion MRI examination can accurately and objectively identify the location,extent and extent of cartilage injury of patellofemoral arthritis,and the 3DFS-SPGR sequence is a little better than that in the FS-FSE-T2W sequence in evaluating the accuracy of the patellar osteoarthritis cartilage injury.
