👉 Hip fluid, also known as synovial fluid, is a viscous, lubricating substance that fills the hip joint capsule, acting as a cushion between the articulating surfaces of the femoral head and acetabulum. This fluid reduces friction during joint movement, facilitates smooth gliding of the bones, and helps maintain joint health by providing nutrients to the cartilage. Composed primarily of water, proteins, and hyaluronic acid, hip fluid also plays a crucial role in shock absorption and shock distribution, ensuring that the joint remains stable and functional under various physical activities. Any imbalance or deficiency in hip fluid can lead to increased friction, wear, and tear, potentially resulting in conditions such as hip osteoarthritis.
