Hyperuricemia as an independent risk factor for achilles tendon rupture in male: a case–control study

Abstract

Abstract Objective To study the correlation between achilles tendon rupture (ATR) and hyperuricemia, also verify the known risk factors for ATR. Methods A retrospective review of 488 subjects was performed (182 with Achilles tendon rupture, 306 controls with ankle sprains). Demographic variables and risk factors for rupture were tabulated and compared. The baseline data and related indicators were compared, and the risk factors of ATR were analyzed by constructing a binary logistic regression model. Results Univariate logistic analysis showed that BMI, smoking, and hyperuricemia were risk factors for the development of ATR (OR = 1.65, 95%CI 1.13–2.42, P = 0.01; OR = 1.47, 95%CI 1.00–2.24, P < 0.05; OR = 2.85, 95%CI 1.84–4.42, P < 0.01). Multifactorial analysis showed that BMI ≥ 25 kg/m2, smoking, and hyperuricemia were independent risk factors for the development of ATR (OR = 1.66, 95%CI 1.11–2.49, P = 0.01; OR = 2.15, 95%CI 1.28–3.60, P < 0.01; OR = 3.06, 95%CI 1.92–4.89, P < 0.01). Among the blood biochemical indicators, total cholesterol (TC) and uric acid (UA) were independent risk factors for the occurrence of ATR (OR = 1.54, 95% CI 1.12–2.12, P = 0.01; OR = 1.01, 95% CI 1.01–1.01, P < 0.01). Conclusion Our study confirmed that, as in previous results, higher BMI, smoking, and total cholesterol are risk factors for ATR, Hyperuricemia may contribute to the development of ATR, and adjunctive tests for TC and UA in the blood biochemistry may be helpful in predicting the risk of ATR.
