Abstract：【Objective】To compare the differences in early grading diagnosis of knee cartilage using different sequences of magnetic resonance imaging (MRI).【Methods】A total of 85 patients with early knee cartilage injuries admitted to our hospital from January 2019 to January 2022 were selected and underwent MRI three-dimensional and two-dimensional sequence examinations. The results of knee arthroscopy were used as the diagnostic criteria to analyze and compare the efficacy of different sequences in the diagnosis of early knee cartilage injuries.【Results】There were 130 knee cartilage injured lesions in 85 patients. Arthroscopy grading showed that 51 lesions were grade 0, 19 were grade 1, 26 were grade 2, 18 were grade 3, and 16 were grade 4. The MRI two-dimensional sequence scan showed 57 lesions at grade 0, 16 at grade 1, 25 at grade 2, 17 at grade 3, and 15 at grade 4. The MRI three-dimensional sequence scan showed that there were 52 cases at grade 0, 22 cases at grade 1, 24 cases at grade 2, 17 cases at garde 3, and 15 garde at level 4. The consistency results between MRI two-dimensional sequence and arthroscopy showed that the Kappa values for grades 0-4 were 0.715, 0.175, 0.341, 0.504, and 0.670, respectively. The consistency analysis between MRI three-dimensional sequence and arthroscopy showed that the Kappa values for grades 0-4 were 0.887, 0.566, 0.653, 0.702, and 0.817, respectively. The sensitivity of MRI three-dimensional sequence in diagnosing grade 0, 2, 3, and 4 knee cartilage injuries was higher than those of two-dimensional sequence, but the difference was not statistically significant (P>0.05); The sensitivity of three-dimensional sequence in diagnosing grade 1 knee cartilage injury is higher than that of two-dimensional sequence, and the difference was statistically significant (P<0.05).【Conclusion】Both 3D and 2D MRI sequences are effective diagnostic methods for early knee cartilage injury, but the sensitivity of MRI 3D sequence grading in diagnosing grade 1 knee cartilage injury is higher than that of MRI 2D sequence.
