These injections can be used to treat mild to moderate osteo-arthritis. The primary goals of Osteo-arthritis treatment are to relieve joint pain and restore function where possible.
In this procedure, a viscosupplement is injected into the knee joint. Hyaluronic acid is a naturally occurring substance found in the synovial (joint) fluid which acts as a lubricant to enable joint surfaces to move smoothly over each other and also as a shock absorber for joint loads. People with osteoarthritis (“wear-and-tear” arthritis) often have a lower-than-normal concentration of hyaluronic acid in their joints. Viscosupplementation may be a therapeutic option for individuals with osteoarthritis of the knee.
During the procedure, if there is any swelling in your knee, Dr Davies may remove (aspirate) the excess fluids before injecting the viscosupplement. Depending on the product used, you will receive one to three injections over several weeks.
A variety of different viscosupplement injections are available. Dr Davies has considerable experience in injecting such products over many years. He would be happy to provide an opinion on the suitability of such injections on an individual patient basis. These injections can be repeated on a 6-12 monthly basis if successful.
Examples of such injections include Ostenil, Synvisc, Monovisc & Durolane.
