A batch of hyaluronic acid injections used to treat osteoarthritis of the knee have been recalled due to contamination with a microbe that can lead to serious side effects.  The injections that have been voluntarily recalled are the Synvisc-One® brand, also called Hylan G-F 20, that were administered to patients between October 25, 2017 and December 18, 2017. The injections were produced by Sanofi Genzyme, a biotech company.

Why is the Injection Being Recalled?

After an increase in the number of adverse events patients experienced, Sanofi Genzyme began an investigation that revealed the presence of microbial contamination. Microbes can increase the risk of infection and other serious side effects.

The lot that has been recalled, 7RSL021, included 18,000 syringes of Synvisc-One®. Doctors, clinics, and pharmacies who received syringes from that lot have been instructed to immediately stop using those injections.

Side Effects of the Synvisc-One® Injection

Some patients receiving the injections have experienced serious side effects. Possible side effects may include:

  • Infections that in some cases could result in hospitalization
  • Emergency room intervention
  • Knee pain
  • Swelling
  • Trouble walking
  • Heat or redness
  • Fluid build-up in or around the knee

How Hyaluronic Acid Injections Work

For patients with osteoarthritis of the knee, hyaluronic acid injections are a treatment option doctors sometimes offer if a patient is not able to control pain with nonsteroidal anti-inflammatory drugs such as aspirin or ibuprofen. Patients who are unable to tolerate these medications may be offered the injection as an alternative.

Hyaluronic acid naturally occurs in the body’s synovial fluid, which is found in joints. The synovial fluid acts as a lubricant and shock absorber, but in people with osteoarthritis, the hyaluronic acid found in synovial fluid breaks down. This leads to joint pain and stiffness. Typically, patients receive several injections over a three to five-week period.

Did You Receive a Hyaluronic Acid Knee Injection During October-December 2017?
