What term is used to refer to inflammation of a joint?

The term "arthritis" specifically refers to inflammation of a joint. It encompasses various types, including osteoarthritis and rheumatoid arthritis, which are characterized by joint pain, swelling, stiffness, and reduced range of motion. Understanding this term is important in physical therapy and related fields as it lays the groundwork for diagnosing and treating conditions associated with joint inflammation.

The other terms mentioned relate to different aspects of joint health and treatment. For instance, "arthroplasty" refers to a surgical procedure to repair or replace a damaged joint, while "arthroscopy" is a minimally invasive surgical technique used to visualize and treat issues within a joint. "Arthralgia," on the other hand, describes joint pain without necessarily indicating inflammation. Hence, while they are all related to joint health, "arthritis" is the specific term that directly addresses joint inflammation.
