Arthroscopic versus open synovectomy in the rheumatoid knee

We report the clinical and radiological results after arthroscopic synovectomy (41 knees) and open capsulosynovectomy (26 knees) in patients with rheumatoid arthritis, with an average follow-up of more than ten years. The clinical outcome was much the same in both groups, but there was gradual deterioration, especially after eight years. Radiological changes of osteoarthritis were worse in the knees treated by open capsulosynovectomy compared with the arthroscopic group. Arthroscopic synovectomy has many advantages and we believe that it is better than open capsulosynovectomy for patients with rheumatoid arthritis of the knee.
