👉 Maintained fluid, also known as synovial fluid, is a viscous, lubricating substance found within the joints of the human body. It plays a crucial role in joint health by reducing friction between the articular cartilage surfaces during movement, thus facilitating smooth and pain-free motion. Produced by specialized cells called synovial fibroblasts within the joint capsule, maintained fluid is rich in hyaluronic acid and lubricin, which contribute to its viscoelastic properties. This fluid also acts as a shock absorber, distributing mechanical loads and protecting the joint from wear and tear. Additionally, it provides nutrients to the cartilage and helps remove metabolic waste products, ensuring the joint remains healthy and functional.
