Controlled clinical trials have shown that viscosupplementation is a safe treatment that improves pain and function in osteoarthritis for shorter or longer periods, whose duration depends not only wear and elimination of the injected substance, but also stability and different molecular weight of each preparation.

The first to appear, animal, requiring up to five applications a week, for a duration of no more than 4 months. The second generation, with development of synthesis, required only 3 doses. Currently available preparations stability and molecular weight, non-animal, suffering very little degradation and get a residence articular at least 8 weeks.
