Clinical significance of ultrasonic scoring system in rheumatoid knee arthritis / 重庆医学

ABSTRACT

Objective To investigate the diagnostic values of ultrasound in rheumatoid knee arthritis and the clinical significance of ultrasonic scoring system.Methods From July 2013 to December 2015,500 cases of patients with rheumatoid knee arthritis in two grade A class 3 hospitals of Lishui City were collected as the observation group and contemporaneous 500 healthy adults were collected as the control group.The knee joint synovial thickness,vascular detection rate in hyperplasia synovium,ultrasound score,rheumatoid arthritis disease activity score,erythrocyte sedimentation rate (ESR),C reactive protein (CRP),suprapatellar bursa effusion,infrapatellar bursa effusion,joint effusion,knee joint cartilage and bone surface were observed in the two groups.Results Compared with the control group,the observation group got a significant increase in knee joint synovial thickness [(0.50±0.19)cm vs.(0.13±0.05) cm,P=0.000)];depth of suprapatellar bursa fluid [(0.62±0.27)cm vs.(0.23±0.05) cm,P=0.000];depth of infrapatellar bursa fluid [(0.58±0.12)cm vs.(0.21±0.04) cm,P=0.000];joint fluid depth [(0.48±0.28)cm vs.(0.12±0.08) cm,P=0.000];ESR [(43.29±12.58)mm/h vs.(12.95±4.39) mm/h,P=0.000)];CRP level [(8.95±3.29)mg/L vs.(3.29±1.54) mg/L,P=0.000)];vascular detection rate in hyperplasia synovium (84.20% vs.13.00%,P=0.000).Moreover the ultrasound score was positively corrected with rheumatoid arthritis disease activity score,CRP level,ESR,suprapatellar bursa fluid depth,infrapatellar bursa fluid depth and joint fluid depth in the patients with rheumatoid arthritis (r=0.583,0.258,0.383,0.219,0.228,0.248;P<0.05).Conclusion Ultrasound has good diagnostic value in the patients with rheumatoid arthritis,and the ultrasonic scoring system can better reflect the severity of the disease.
