Abstract Objective: To explore the ultrasonic characteristics and diagnostic value of joint lesions in patients with rheumatoid arthritis (RA). Methods: The clinical data of 60 RA patients (observation group) who were admitted to the hospital from January 2018 to January 2020 were retrospectively analyzed. Another 50 healthy people who underwent physical examination in the hospital during the same period were enrolled as control group. All underwent ultrasound examination. The ultrasonic features of joint lesions were observed. The synovial thickness, depth of joint fluid and bursa suprapatellaris fluid, and blood flow index of synovial artery were compared between the two groups. Results: In observation group, there were 54 patients with irregular synovial thickness, whose surface was rough. There were villi-like structures protruding into the effusion synovial cavity. There were 48 cases with blood flow signals and 50 cases with different degree of joint fluid, which was located at bursa suprapatellaris. There were 15 patients with blurred knee articular cartilage edge, cartilages were thinned, and cartilage surface was rough. There was worm-bittenlike damage of cartilage bone in some patients. Depth of bursa suprapatellaris fluid, synovial thickness and depth of joint fluidin observation group were higher than those in control group, while blood flow index of synovial artery was lower than that in control group (P<0.05). The detection rates of intra-synovial blood flow in knee, bursa suprapatellaris fluid and synovial thickening in observation group were 80.00%, 83.33%and 90.00%, respectively. Conclusion: Ultrasound has a high detection rate in early knee joint lesions in RA patients, which can accurately reflect pathological changes, and provide reference for clinical treatment.
