Having knee osteoarthritis may increase the likelihood of developing hypertension, according to findings presented at the World Congress on Osteoporosis, Osteoarthritis, and Musculoskeletal Diseases, March 23-26, 2017, in Florence, Italy.

An international team of researchers from Italy, Belgium, and the United Kingdom collected data from the Osteoarthritis Initiative, a multicenter, longitudinal, observational study.

Incident hypertension was defined as systolic blood pressure >140 mm Hg and/or diastolic blood pressure >90 mm Hg. Radiologic and clinical assessment were used to identify knee osteoarthritis.

Of the 3558 patients with normal blood pressure at baseline, 1930 had knee osteoarthritis and 1628 did not. There was a significantly higher incidence of hypertension in patients with knee osteoarthritis compared with patients without osteoarthritis (60 vs 55 per 1000 person years; P <.0001).

After adjustment for confounders, patients with knee osteoarthritis had a 13% higher chance of developing hypertension (hazard ratio [HR] 1.13; 95% CI, 1.01-1.26; P =.03).

“Our data suggest that blood pressure should be monitored in this population and prevent[ive]ing interventions [be] provided to mitigate the potential adverse consequences of hypertension,” the researchers wrote.
