liigesõõne

liigesõõne refers to the joint cavity, the space between the articulating bones within a synovial joint. This space is filled with synovial fluid, a viscous substance that lubricates the joint, reduces friction, and nourishes the articular cartilage. The joint cavity is enclosed by a joint capsule, which has two layers: the outer fibrous membrane and the inner synovial membrane. The synovial membrane is responsible for producing and secreting the synovial fluid. The integrity of the joint cavity and the quality of the synovial fluid are crucial for smooth and painless joint movement. Conditions affecting the joint cavity, such as inflammation or the presence of loose bodies, can lead to pain, stiffness, and limited mobility. Imaging techniques like MRI can visualize the joint cavity and help diagnose various joint pathologies.
