How many grades of arthritis is there?

Arthritis typically refers to a group of over 100 different conditions, but it is often categorized into several main types, including osteoarthritis, rheumatoid arthritis, and psoriatic arthritis. The severity of arthritis is commonly assessed using a grading system that ranges from mild to severe, often based on symptoms and joint damage. While the grading may vary by specific type and guidelines, there isn't a universally standardized number of grades across all arthritis types. Instead, evaluations are generally tailored to the individual condition and its impact on joint function.
