When you have osteoarthritis (OA), the hyaluronic acid (HA) in the synovial fluid in your joint becomes diluted and breaks down.1 HA is a natural substance found in your joints and in the synovial fluid that fills your joints. It acts like a lubricant and a cushion in the joint. If there is less HA in the joint, inflammation can increase and cartilage in the joint can degrade.1 This results in pain, causing you to limit your movement, which, in turn, leads to further damage to the joint. Healthy synovial fluid has a high concentration of the natural substance HA.
Non-surgical treatment options for OA are a combination of physiotherapy, pain medication and HA injections.
