High blood pressure and OA: friends or foes?

Vascular aetiology of osteoarthritis (OA) has been proposed for decades(1,2). Very recently, Funck-Brentano and colleagues' reported a novel causal relationship between blood pressure and OA, entitled "causal factors for knee, hip and hand osteoarthritis: a Mendelian randomization study in the UK Biobank"(3), which provide us a new insight into the vascular origin of OA pathologies. We appreciate the authors' dedicated efforts in big data analytics to unravel the puzzle of OA, a multi-factorial prevalent debilitating disability-associated chronic condition. Yet there are a few issues concerning the data comprehensiveness, accuracy and representativeness worth mentioning. This article is protected by copyright. All rights reserved.
