Liigeseõõnsus

Liigeseõõnsus refers to the space between the articular cartilages of bones within a synovial joint. This cavity is filled with synovial fluid, a viscous liquid that lubricates the joint, reduces friction, and provides nourishment to the articular cartilage. The synovial fluid is produced by the synovial membrane, which lines the inner surface of the joint capsule, excluding the articular cartilage itself. The integrity and volume of the joint cavity are crucial for proper joint function and mobility. Inflammation or injury to the joint can lead to changes in the amount or composition of the synovial fluid, which can result in pain, stiffness, and reduced range of motion. Conditions like arthritis often involve inflammation and swelling of the joint cavity. In some cases, diagnostic procedures like arthrocentesis involve drawing fluid from the joint cavity for analysis. The structure of the joint cavity is maintained by the surrounding joint capsule and ligaments, which provide stability.
