Hello Dear,
Hyaluronan, the name of the substance in Synvisc, is secreted by cells in the cartilage of joints. Hyaluronan is one of the major molecular components of
joint fluid, and it gives the
joint fluid, also called synovial fluid, its viscous, slippery quality. The high viscosity of synovial fluid allows for the cartilage surfaces of joints to glide upon each other in a smooth fashion. By injecting Synvisc in a knee, some people consider this a so-called joint lubrication.
