Abstract:
Objective To investigate the correlation between wholeGorgan MRI score (WORMS)and pain in patients with knee osteoarthritis (OA).Methods 1 1 9 patients with knee OA were enrolled,and The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)was used to estimate the pain.Knees of all the subj ects underwent scanning with sagittal,coronal,transverse TSEG T2 WIGFS and sagittal 3DGFLASHGWE sequences at 3.0T MR.The pathological changes of knee cartilage lesions,subarticular bone marrow edema (BME),bone cysts,bone attrition,osteophytes,meniscal inj ury,ligament inj ury,synovial thickening and joint effusion were evaluated according to the WORMS.The correlations between the above pathological changes and the pain were analyzed.Results There were significant and positive correlations between articular cartilage lesions and osteophytes,articular cartilage lesions and BME,BME and cyst,bone attrition and osteophytes,and BME and osteophytes,with the correlation coefficients of 0.6 70,0.5 9 8,0.5 1 8,0.5 1 4 and 0.505 ,respectively (P＜0.05 ).Multiple regression analysis showed that BME,bone attrition,synovial thickening and joint effusion were the main factors affecting the severity of pain after adj usted for age and BMI (P＜0.05).Conclusion The source of OA pain is multifactorial.The severity of BME,bone attrition,synovial thickening and joint effusion are the main factors associated with joint pain.As a nonGinvasive examination method,MR can make a comprehensive evaluation of the pathological changes of knee OA.
