Osteoarthritis (OA) is a condition, which usually develops gradually, over several years, and affects a number of different joints. The cause is unknown, but it does appear more in females than males and often starts after the menopause. This can lead to it being seen as part of the ageing process.

For some people the changes are so subtle and develop over such a long time that they are hardly noticed. For others, problems may worsen over a number of years, after which the condition may settle and become easier to manage. When the overall disease process finishes, joints may look knobbly, but are usually less painful. In some cases they become pain free and, despite their appearance, still enable you to carry out most everyday tasks.

Osteoarthritis used to be considered wear and tear arthritis, but it is now thought there are many more factors than age and use that contribute to the development of osteoarthritis – including obesity, past injury and genetics.
