    Abstract:
    PURPOSE: To investigate the effects of arthroscopic wrist synovectomy on the clinical course of rheumatoid arthritis in a large series with long-term follow-up. METHODS: We performed arthroscopic synovectomy on 56 wrists in 49 patients with rheumatoid arthritis. At a mean follow-up of 7.9 years (range, 5-12 y), we evaluated pain and patient satisfaction using a visual analog scale and assessed overall function using the Mayo wrist score. Radiographic stage was graded according to Larsen stage. We determined clinical outcomes on the recurrence of wrist synovitis, which we evaluated by symptoms of pain and swelling and physical examination. Preoperative variables were statistically analyzed to find factors that could influence the results. RESULTS: The mean visual analog scale score for wrist pain decreased from 6.3 to 1.7, and the mean Mayo wrist score (evaluated in 39 wrists) improved from 48 (range, 5-70) to 76 (range, 55-100). The mean visual analog scale score for patient satisfaction was 7.9. At final follow-up, synovitis was controlled in 42 wrists (75%) and recurred in the others. The mean Larsen stage progressed from 2.2 to 3.3. Analysis of preoperative variables revealed no factors that significantly affected clinical outcomes in terms of sex, age, duration of wrist symptom, preoperative serologic inflammatory markers, or Larsen stage. CONCLUSIONS: Arthroscopic synovectomy of the wrist can provide pain relief and functional improvement with control of synovitis in 75% of rheumatoid wrists that have not responded to medication. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.
