Which medical term describes a joint that becomes stiff and painful as a result of inflammation and swelling?

Rheumatoid arthritis is the medical term that refers to a chronic inflammatory disorder affecting the joints. It is characterized by the inflammation of the synovial membrane, which can lead to swelling, stiffness, and pain in the affected joints. This condition often results in damage to the cartilage and bones, further exacerbating discomfort and loss of function.

In cases of rheumatoid arthritis, the immune system mistakenly attacks the joints, leading to persistent inflammation. This inflammation not only causes pain but can also lead to joint deformity and reduced range of motion over time. The symptoms can be particularly pronounced after periods of inactivity, contributing to morning stiffness that many people with the condition experience.

In contrast, other terms do not adequately describe the combination of inflammation, swelling, and joint pain. For example, osteoarthritis generally involves degeneration of cartilage due to wear and tear rather than inflammation. Apnea refers to a temporary cessation of breathing and is unrelated to joint health. Contracture describes the shortening and hardening of muscles or tendons, which is a different issue that does not specifically involve inflammation.
