Viscosupplementation has been shown to relieve pain in many patients who have not responded to other nonsurgical methods. The intra-articular injection technique was first used in Europe (1987), and was approved by the U.S. Food and Drug Administration in 1997.

Intra-articular injections provide a local therapeutic intervention with two major advantages: high concentration of the active ingredient, being the latter administered directly into the joint, and the absence, or remarkable reduction, of systemic side effects.

A variety of products, administered locally, have shown to improve the patient’s symptoms and may also be effective in controlling disease progression in degenerative joint disease.

Intra-articular injections of hyaluronic acid can be successfully used in the treatment of primary and secondary arthritis, as well as in case of traumatic injuries and post-traumatic arthritis.

Intra-articular injections may be repeated after a period of time if necessary, since they have a long-term effectiveness, with respect to other products requiring continuous intake.
