What is the most common form of arthritis?

Osteoarthritis is indeed the most common form of arthritis experienced by individuals. It is characterized by the degeneration of cartilage and the underlying bone in a joint, leading to pain, stiffness, and decreased mobility. This condition typically affects weight-bearing joints such as the knees, hips, and spine, and is often associated with the aging process as well as wear and tear over time. Due to its prevalence in older populations and the impact of obesity and sedentary lifestyles, osteoarthritis represents a significant proportion of arthritis cases.

In contrast, rheumatoid arthritis is an autoimmune condition that affects a smaller percentage of the population and can present in various ways, including systemic symptoms. Gout, while a serious form of arthritis caused by the accumulation of uric acid crystals, affects a minority of individuals and is more episodic rather than chronic. Psoriatic arthritis, which can accompany psoriasis, also affects a smaller group compared to osteoarthritis. Thus, osteoarthritis holds the distinction of being the most commonly diagnosed type of arthritis.
