The aim of the present study was to compare histological findings and clinical symptoms of patients with advanced stages of rheumatoid arthritis (RA). Synovial tissue specimens were obtained during reconstructive knee surgery from 93 RA patients (18 men; 75 women). The histological assessments of specimens were evaluated using two histological scoring systems reported by Rooney and Koizumi. Clinical symptoms (duration of morning stiffness, joint score, grip strength), laboratory data (erythrocyte sedimentation ratio, C‐reactive protein (CRP), rheumatoid factor), X‐ray findings (Larsen score) and drug usage were assessed before surgery. Significant statistical correlations between both histological scoring systems were observed; however, there was no significant correlation between the clinical findings and the histological scoring systems. A statistically significant correlation was found between the levels of CRP and Koizumi's scoring system. In addition, Koizumi score correlated significantly to X‐ray findings. Rooney's scoring system had an inverse correlation to methotrexate history. Histological findings do not correlate to simultaneous clinical symptoms in advanced RA patients. However, our data indicate that observed histological changes reflect X‐ray damage.
