Abstract
Objective: To assess the association between uric acid and patterns of oste oarthritis (OA). Methods: OA patterns were studied in 809 patients with arthroplasty due to hip or knee OA. Patients with OA were categorized as having bilateral or ge neralized OA according to the presence of radiographic OA in the contralate ral or different finger joints. Odds ratios (OR) and 95% confidence interva ls (CI) for thirds of serum uric acid and OA patterns were estimated with m ultivariable logistic regression. Results: Eighty-five percent of the participants had bilateral OA and 26% g eneralized OA. A positive association between serum uric acid and generaliz ed OA was observed in patients with hip OA (highest versus lowest tertile O R = 3.5; 95% CI: 1.3-9.1), but not among patients with knee OA (correspondi ng OR=1.1). Serum uric acid was not associated with bilateral OA. Conclusion: Our results suggest a possible role of elevated serum uric acid in the multifactorial etiology of generalized OA.
