Orthovisc is a non-animal viscosupplement indicated for the treatment of osteoarthritis (OA) of the knee. The product is delivered in a single-use syringe, and it is injected into the joint, repeating 3 to 4 intra-articular injections, one week apart. It lubricates and protects the knee joint, providing pain reduction for up to 6 months.
Orthovisc consists of an ultra-pure, high molecular weight injectable hyaluronic acid (HA) viscosupplement. It is comprised of highly purified sodium hyaluronate (NaHA) and it is both biocompatible and resorbable. The effect of the treatment is partially based on the product’s high concentrate of HA (15 mg/mL), which is currently available in a multi-injection treatment.
