Abstract：Objective To explore early diagnosis value of MRI in rheumatoid arthritis (RA) of the knee, and to observe the clinical effectiveness of arthroscopic synovectomy. Methods Six-eight patients with knee RA were treated by arthroscopic synovectomy in the People's Hospital of Meizhu from January 2008 to December 2012, and their clinical data were analyzed retrospectively. All patients performed preoperative X-ray, gadolinium contrast enhanced MRI and postoperative pathological examination, the accurate rates of two imaging methods were observed, Lysholm score and blood rheumatoid factor (RF), erythrocyte sedimentation rate (ESR) and C-reative protein (CRP) before the surgery and 3, 6, 12 months after the surgery were recorded respectively. Results According to the pathological results, the accurate rate of X-ray and MRI examination was 66% (29/44)and 97% (29/30) respectively, there was statistical difference between two diagnosis methods (P <0.05). All patients were followed up for 12-38 months, with the average of 18.6 months. Postopertive Lysholm score and blood RF, ESR and CRP were higher than preoperative ones, the differences had statistical significance (P <0.05). Conclusions Compared with X-ray, MRI was more accurate to early diagnosis of RA of the knee. Arthroscopic synovectomy is a good surgical option for knee, after the surgery, the knee joint function of the patient has been improved obviously, the postoperative clinical parameters such as blood RF, ESR and CRP enhanced markedly, and as a result, the satisfied short-term effect could be obtained.
