Risk Factors and Symptoms of Osteoarthritis
Risk Factors for Osteoarthritis Osteoarthritis has several risk factors that can be broken down into three categories: modifiable local risk factors, modifiable systemic risk factors, and non-modifiable systemic risk factors. Modifiable local risk factors are factors that occur near the site of OA that can be altered. These include muscle strength, physical activity, joint injury, joint alignment and leg length in equitability. Modifiable systemic risk factors occur on a larger scale and can also be modified such as obesity and diet. Non-modifiable system risk factors are factors that influence OA risk but cannot be changed. These include age, sex, genetics, and ethnicity. 1) Age One of the greatest risk factors is age, which makes sense as years of wear on the bones leads to the breakdown of joint integrity. OA diagnosis increases in women especially between the ages of 60 and 64. This increase in risk with age is thought to be due to a variety of age-related changes such as a reduced capacity for joint tissue to adjust to biomechanical challenges, increased bone turnover, and accumulation of reactive oxygen that can damage articular tissue (tissue that covers the ends of the bones where they meet). 2) Gender Women are at a greater risk for OA and typically experience more severe forms of the disease.
