Intra-articular injections of hyaluronic acid, which mimics the lubricating properties of natural synovial fluid and lessens friction and pain in the osteoarthritic knee joint, has become increasingly popular for treating osteoarthritis. However, of the seven formulations available in the US, none have been proven clinically superior and they have only limited long-term benefit to the patient. Flex Biomedical Inc. is working to address these concerns with a single-injection synthetic polymer alternative to HA.
