Summary of Background Data: Extrinsic risk factors for Achilles tendon rupture, such as fluoroquinolones or local injections with corticosteroids, are well recognized. Genetic predisposition is another factor that has been proposed, since this pathology is more frequently seen in certain populations. Thus, it can be theorized that patients who have presented an Achilles tendon rupture are at higher risk of rupturing their contralateral tendon compared to general population. Previous reports by Arøen et al suggest than 10 out of 154 patients presented a contralateral injury (OR:176). Methods: Data from patients operated on from an acute Achilles tendon rupture were retrospectively retrieved from two academic centers. Patients were included if they had at least 2 years since their surgery and were willing to participate in the study. Each patient answered a telephone questionnaire regarding prior symptoms, contralateral rupture and risk factors (flouroquinolones, local corticosteroids and tobacco). Patients were excluded if they did not answer all questions or were unable to be contacted. Since data in our population is lacking, we used the overall incidence of Achilles tendon rupture published by Sheth et al. as the expected rate of Achilles tendon rupture in the general population. This value was compared to our cohort’s contralateral injury incidence to obtain an effect measure (odds ratio). Results: 246 consecutive Achilles tendon ruptures were treated during a 6-year follow-up period (2008-2016). 25 patients (8.5%) ruptured their contralateral tendon, equivalent to an incidence of 1407 ruptures per 100.000 inhabitants per year. Reported incidence of Achilles tendon rupture in the general population is 29 per 100.000 inhabitants per year. Odds ratio compared to the general population was 49.2 (95% CI: 34.1 – 73.7) (p |
