Abstract:
Objective To explore the application value of high frequency ultrasound and MRI in knee osteoarthritis.Methods 94 patients with knee pain as the main clinical manifestations in our hospital from January to December 2017 were retrospectively analyzed. All patients underwent high-frequency ultrasound, MRI, and arthroscopy. The results of arthroscopy were used as the gold standard, and the signs of high-frequency ultrasound and MRI examinations were summarized and compared with the results of arthroscopy. The sensitivity and specificity between high-frequency ultrasound and MRI in the diagnosis of knee osteoarthritis were compared. Results Consistency analysis showed that highfrequency ultrasound, MRI examination with arthroscopy consistent results were good (Kappa=0.63, 0.61, P<0.05). The sensitivity and specificity of high-frequency ultrasonography for knee osteoarthritis were 86.5％ and 85.0％, respectively, and the sensitivity and specificity of MRI was 89.2％ and 75.0％, respectively.The difference between high-frequency ultrasound and MRI was not statistically significant (P>0.05). Conclusion High-frequency ultrasound and MRI have good application value in the diagnosis of knee osteoarthritis, and the results are consistent with that of arthroscopy.Compared with MRI, high-frequency ultrasound diagnosis of knee osteoarthritis has no difference in sensitivity and specificity, and can be used for routine screening of knee osteoarthritis.
