👉 The daughter fluid, also known as the residual or retentive fluid, is a component of synovial fluid that forms when proteolytic enzymes, such as hyaluronidase, break down the larger molecules in the original synovial fluid. This process results in a fluid with reduced viscosity and altered composition, which can affect the lubricating and protective properties of synovial fluid. The daughter fluid contains smaller fragments of hyaluronic acid, proteoglycans, and other components, which may have different roles in joint health and function. Despite its reduced properties, the daughter fluid still plays a crucial role in maintaining joint mobility and cushioning during movement.
