A further conservative option for Osteoarthritis is viscosupplementation. This involves injecting a gel-like substance known as Hyaluronic acid into a joint. Hyaluronic acid contains sodium hyaluronate which is a naturally occurring substance that is found in the synovial membrane/fluid which helps lubricate and act as a shock absorber within a healthy joint. In osteoathritis the quality of this substance declines, by re-introducing this it acts as a lubricant to enable the joint to function better, causing less irritation and in turn reducing pain.
The most commonly injected area is the knee; however, Hyaluronic acid can be used at a number of different anatomical locations. These injections are not only limited to osteoarthritis and can sometimes be used in other musculoskeletal conditions such as tendinopathies.
