Full Answer

Joints contain a natural substance called synovial fluid that provides lubrication, states the Arthritis Foundation. Osteoarthritis destroys the hyaluronic acid in the synovial fluid, which causes the joints to stiffen and grind together. Hyaluronic acid injections are approved by the Food and Drug Administration as a treatment for arthritic knees. There is scientific evidence and clinical experience that suggest hyaluronic acid injections are an effective treatment for arthritic knees. The injections are often used instead of nonsteroidal anti-inflammatory drugs and are usually given once a week for at least three weeks.

Hyaluronic acid injections do not provide immediate relief from osteoarthritis symptoms, says the Arthritis Foundation. In some cases, it takes up to five weeks for a person to experience pain relief. Although it takes a while for the injection to have an effect, maximum relief of arthritic symptoms lasts for about three months. Each patient responds differently to the injection. In some cases, patients experience pain relief for up to two years, while others have no decrease in symptoms.
