Abstract
The prospective study of 32 knees in 26 patients with rheumatoid arthritis was carried out with an average followup of 3 years. Relief of pain and control of inflammation locally were obtained in 22 of 32 knees (69%). Articular cartilage was preserved in 20 of 28 knees (71%) and the synovitis recurred in 9 knees (28%), 7 of which showed progressive loss of cartilage. Therefore, it appears that synovectomy, if performed at a stage in which articular cartilage is still normal and after medical therapy has failed, is a very effective method for preserving articular cartilage and controlling inflammation locally. However, with a longer followup the disease with loss of articular cartilage will recur in a large number of cases. In patients whose disease progresses rapidly, no form of therapy effectively controls joint destruction.
