Hyalgan (Hyaluronic Acid) Injection


Similar to Synvisc, Hyalgan is a viscosupplementation procedure that uses hyaluronic acid to provide cushioning and relief for your joints, namely the knees. It has a lighter molecular weight than Synvisc, but is also a proven method of treatment for osteoarthritis.

How It's Used

Hyalgan therapy consists of one injection each week, for five weeks. It’s administered under general anesthesia, and the accuracy of its placement is ensured via ultrasound guidance (shown above with Dr. Webber). It is a fast, roughly 20-30 minute procedure, and you can walk out the same day.

Hyalgan can reduce knee pain caused by osteoarthritis for up to 6 months.

Side Effects

Common side effects of Hyalgan include:

  • injection site reactions (pain, swelling, redness, warmth, bruising, stiffness, or puffiness),

  • headache

  • nausea

  • stomach pain

  • back pain

  • numbness or tingly feeling

  • cold symptoms (stuffy nose, sneezing, sore throat)

  • tired feeling

  • itching or skin irritation around the knee

Please note: Immediately consult your doctor if you develop fever, severe side effects, or the pain and swelling fail to resolve after 48 hours following the injection.
