Satisfactory results were achieved by synovectomy in 24 of 26 rheumatoid knee joints. Follow-up studies averaged four years. Clinically, synovectomy arrested the rheumatoid process locally and prevented progressive joint destruction. The favorable results suggest that perhaps synovectomy of the knee joint should be performed more frequently in the patient with rheumatoid arthritis.
