The surgical management of tophaceous gout has been well documented in the literature, including its effect on foot pain and disability. To date, there have been no systematic reviews assessing the quality of the literature relating to the operative management of tophaceous gout and the outcomes in the foot and ankle.
The following electronic databases were searched (1980-2014): Allied and Complementary Medicine, Cumulative Index to Nursing and Allied Health Literature, MEDLINE, Scopus, and the Cochrane Library. The articles identified were published in English and included adult participants (age ≥18 years) with diagnosed gout and surgical intervention to the foot and ankle. The Downs and Black Quality Index was modified to assess the quality of the articles being reviewed.
Six articles were reviewed and were of moderate quality (mean quality score of 71%). Surgical management was conducted on men (88%) with a mean age of 52 years. There was wide variation in the types of surgical procedures performed, with 28% of studies reporting surgery to the first metatarsophalangeal joint. Most studies were retrospective. A wide range of outcome measures were reported: foot pain, function, preoperative and postoperative activity levels, monitoring of uric acid levels, and patient satisfaction after surgery.
The review demonstrated a limited number of good-quality studies. Several surgical procedures for the foot and ankle in people with chronic tophaceous gout were reported. Future studies should include prospective observational studies using validated and reliable patient-reported outcome measures.
