Objective To investigate the clinical outcome of arthroscopic synovectomy for inpatients with rheumatoid knee. Methods Arthroscopic synovectomy was performed on 32 rheumatoid knees in 31 patients, including 10 males and 21 females with an average age of (35.5±8.7) years (23 to 51 years) between January 2009 and March 2013. The patients' mean morbidity duration was (12.0±5.5) years (5 to 21 years). X-ray examination results were observed before the operation, 1 year and 2 years after the operation, and then Larsen method was used for assessment. Pain alleviation, C-reactive protein (CRP), rheumatoid factors (RF), and erythrocyte sedimentation rate (ESR) were compared before and after operation. Results The follow-up averaged 1.7 years, and the average pain score decreased from 4.23±0.96 before surgery to 2.21±0.87 one year after surgery; RF decreased from (265.3±120.1) U/mL to (89.2±12.1) U/mL; CRP decreased from (89.36±32.12) mg/L to (20.12±10.21) mg/L; and ESR decreased from (86.56±12.32) mm/h to (45.23±11.12) mm/h. Conclusion Arthroscopic synovectomy can effectively relieve pain and delay radiologic progression in patients with rheumatoid knees.
