Synvisc One Product specifications
Synvisc One is a viscosupplement formulated to aid in the management of symptoms associated with knee osteoarthritis. Made of hyaluronan derivatives called hylan, this gel-like substance supplements and restores the shock-absorbing and lubricating properties of synovial fluid that is diminished in patients with osteoarthritis. This is a single dose treatment that is delivered via intraarticular injection to the affected knee, making this a convenient treatment option for patients.
What Synvisc One is formulated to do
Synvisc One is an orthopedic injectable used to treat pain associated with knee osteoarthritis. Patients who have this chronic condition suffer from soreness or stiffness in the knees after inactivity or overuse, swelling around the knees, and/or knee pain that worsens with activity. In some instances, this may become a debilitating condition that negatively affects the quality of life. When this happens, it is important that the patient is able to manage the associated pain and discomfort effectively and effortlessly to maintain their desired lifestyle.
If conventional treatments, such as physical therapy and pain medications (e.g. ibuprofen, acetaminophen), can no longer provide sufficient knee pain relief, patients may consider viscosupplementation as a treatment option. This therapeutic method typically involves a series of injections of high concentrations of hyaluronan, a compound found in large quantities in the synovial fluid that provides lubrication and cushioning in the knee joint.
Synvisc One is unique in its class of viscosupplements in two regards: its composition, and its course of treatment. Unlike other viscosupplements, Synvisc One is made up of hylan, which are cross-linked derivatives of hyaluronan. In addition, Synvisc One is a single-dose treatment, meaning that multiple visits are not required for this treatment.
The Synvisc One orthopedic injection is manufactured by Genzyme Biosurgery, a division of Genzyme Corporation, which is a subsidiary of Sanofi, a global pharmaceutical and biotech company.
Synvisc One has its origins in the United States of America.

What are the differences between the product range?
A related product is Synvisc, which has a different treatment regimen requiring multiple doses.
- Synvisc One is meant to be administered as a single intra-articular injection. Hence, follow standard procedures for injections, such as following an aseptic technique.
- Remove any joint effusion or synovial fluid before injecting Synvisc One using an 18- to 20-gauge needle. Do not reuse the syringe for administering Synvisc One; however, the same needle may be used.
- Uncap the tip of the prefilled treatment syringe by twisting the tip and then pulling it off.
- Secure the needle tightly while holding the Luer hub: this will ensure a tight seal and prevent leakages.
- Inject the full 6ml dose into 1 knee.
- Patients should avoid any type of strenuous or prolonged weight-bearing activities for approximately 48 hours after treatment.
Synvisc One is a viscoelastic, sterile, non-pyrogenic solution of hylan A and hylan B hydrated gel in a buffered physiological saline solution, with a pH of 7.2. Hylans are derivatives of hyaluronan, a polysaccharide present in large quantities in healthy synovial fluid. Synvisc One combines three 2ml doses (16mg each) of a complete Synvisc treatment course into a single 6ml dose contained in a 10ml syringe.
