What differentiates arthropathies from other conditions affecting joints?

Arthropathies, which refer to diseases that primarily affect the joints, can be specifically distinguished from other conditions by the presence or absence of synovial membrane inflammation. Inflammatory arthropathies, such as rheumatoid arthritis, are characterized by the inflammation of the synovial membrane, which can lead to swelling, pain, and potential destruction of the joint. In contrast, non-inflammatory conditions like osteoarthritis do not involve such inflammation, although they can still affect joint function and cause pain.

This distinction regarding synovial membrane involvement is crucial, as it guides diagnosis and treatment approaches. Therapies may differ significantly between inflammatory and non-inflammatory arthropathies, making the identification of inflammation a key factor in the classification of joint diseases.
