People presenting with persistent joint pain over the age 45 years are often given the diagnosis of Osteoarthritis (OA). Osteoarthritis presents as normal age related changes in joints. OA is not simply a process of the wear and tear but an active process of joint surface remodelling as the joint tries to repair itself. Sometimes the changes which occur within our joints can cause pain over time. Many factors influence the onset and the progression of the condition including your genetic ‘make-up’ and other health related problems such as obesity.
