Osteoarthritis (OA) is the most common form of chronic joint disease (one that lasts for a long time). The point at which two bones meet is known as a joint. Cartilage, a type of protective tissue, covers the articulating surfaces of these bones at their ends. This cartilage deteriorates as a result of osteoarthritis, which results in the bones within the joint rubbing against one another. Although OA strikes adults of all ages most frequently in those over the age of 60, it can strike adults of any age. There are a few different names for osteoarthritis, including degenerative joint disease, wear-and-tear arthritis, and degenerative arthritis. Osteoarthritis can be caused by ageing, hereditary factors, injury from trauma or disease, or even just normal wear and tear over time. Joint damage is the root of osteoarthritis. Because this damage can accumulate over time, one of the primary causes of the joint damage that leads to osteoarthritis is ageing. The more years you’ve lived, the more wear and tear your joints have been subjected to.
