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.

Injectable products that can alleviate pain and even reverse the disease process are on the horizon for treating degenerative orthopedic and spinal conditions, such as damaged articular joint cartilage and deteriorated spinal discs. With no available long-term treatment options for these conditions short of invasive surgical procedures like joint replacement or spinal fusion, injectable technologies that offer the possibility of being used upstream in the continuum of care are potential billion-dollar market opportunities. In fact, in a post health care reform environment, injectable therapies may prove to be the most cost-effective way for treating many degenerative conditions.
