Orthovisc® Product Specifications
If a patient is suffering from knee pain, Orthovisc may be the solution. Made of a substance consisting of high molecular weight hyaluronic acid, Orthovisc is designed to closely mimic synovial fluid that is normally lost with the advent of osteoarthritis of the knee, restoring support and lubrication around the joint, thus alleviating discomfort and pain. The treatment consists of a series of orthopedic injections to the affected knee and is meant as a treatment in patients who have not responded to conventional treatment for pain due to knee osteoarthritis.
What Orthovisc is formulated to do
Orthovisc, also known as hyaluronan or hyaluronic acid, is a series of orthopedic injections used for pain management of osteoarthritis, referred to as viscosupplementation.
Viscosupplementation is a therapeutic method used to treat osteoarthritis pain in patients who have not adequately responded to conventional treatments like physical therapy and pain medication. It involves replacing or supplementing synovial fluid surrounding the affected joint with a substance designed to match the rheological and physiological properties of healthy synovial fluid. With that, the cushioning and lubricating properties of synovial fluid are restored, minimizing the symptoms related to osteoarthritis.
Reported benefits from treatment using Orthovisc include a reduction in joint pain and improvement in functionality, duration of effects of up to 26 weeks, and no reported pseudoseptic reactions.
Orthovisc is manufactured by Anika Therapeutics, a medical technology company based in Massachusetts, USA that specializes in the development of products for pain management, tissue regeneration and wound healing.
