👉 The BK fluid, also known as BK synovial fluid, is a viscous, colorless, and slightly yellowish fluid found in the knee joint, specifically within the synovial membrane that lines the joint capsule. It plays a crucial role in lubricating and nourishing the cartilage, reducing friction during joint movement, and absorbing shock. The BK fluid is rich in hyaluronic acid, which contributes to its viscoelastic properties, allowing it to maintain a consistent viscosity under varying pressure conditions. It also contains proteins, glucose, and various ions that support the health of the joint tissues and facilitate nutrient exchange between the synovial membrane and the cartilage.
