Which term is associated with inflammation of the joints?

Arthritis refers specifically to the inflammation of the joints, characterized by pain, swelling, stiffness, and decreased range of motion in the affected areas. It can involve various forms, including osteoarthritis, rheumatoid arthritis, and more, each with distinct underlying causes and treatment approaches. This term is universally recognized in both medical terminology and patient care contexts when discussing joint-related disorders.

Other conditions listed, such as osteoporosis, refer to a decrease in bone density and strength, which can lead to fractures but does not directly involve joint inflammation. Gout, while it specifically affects the joints and involves an inflammatory response due to uric acid crystals, is considered a specific type of arthritis. Fibromyalgia is primarily a disorder characterized by widespread musculoskeletal pain and does not exclusively pertain to joint inflammation, instead focusing on muscle and soft tissue. Thus, the term that broadly and accurately reflects joint inflammation is arthritis.
