Differentiation of Intra-articular and Abarticular Lesions

• abarticular — A medical term used to describe structures, inflammatory processes, or symptoms located outside a joint, but in its immediate vicinity (tendons, ligaments, bursa). Abarticular rheumatism (such as tendinitis or bursitis) manifests as periarticular pain without affecting the cartilage or internal synovial membrane of the joint itself.
