Weitz & Luxenberg Accepting Synvisc-One Lawsuits
For patients with osteoarthritis, any relief from knee pain and other uncomfortable arthritis symptoms may seem like a good thing. However, sometimes something marketed as a remedy can cause a worse problem.
The manufacturer of one type of an injectable knee arthritis gel has voluntarily recalled more than 12,000 potentially contaminated syringes.
The name of the manufacturer is Sanofi Genzyme. The name of the recalled contaminated knee arthritis syringes is Synvisc-One.
Contamination of any kind can be serious because of possible adverse reactions to the contaminant, in this case a gram-negative bacteria.
Weitz & Luxenberg is currently accepting cases of people who were administered a recalled contaminated Synvisc-One syringe injection for the osteoarthritis in their knee and suffered serious complications.
We are also interested in hearing from you if a loved one received this type of shot and experienced severe complications, or even died.
Synvisc-One Injection Side Effects
A recalled lot of Synvisc-One arthritis syringes were found to be potentially contaminated with gram-negative bacteria. These bacteria pose unique risks because they can result in infections that are resistant to many types of antibiotics. This means treating a gram-negative bacterial infection can be difficult.(1)
Sanofi Genzyme has notified the public that possible complications from a Synvisc-One syringe injection include:(2)
- Fluid buildup in or around the knee
We are interested in hearing from people who suffered serious Synvisc-One injection side effects within one week of receiving an administration of the gel.
We are accepting Synvisc-One lawsuits on behalf of those harmed by contaminated Synvisc-One syringes that were recalled.
Tainted Lot of Arthritis Syringes
The potentially contaminated Synvisc-One arthritis syringes were from one lot: lot identification number 7RSL021. These syringes were distributed from October 25, 2017, through early November. The manufacturer recalled these syringes on December 11, 2017.
These shots are administered directly to the knee joint in an effort to alleviate pain and other symptoms caused by osteoarthritis. Some Synvisc-One shots people received, however, may have been contaminated.
Contaminated shots could inject harmful bacteria directly into the knee joint, potentially resulting in infections and other side effects.

Some Synvisc-One Arthritis Syringes Voluntarily Recalled
On December 11, 2017, Sanofi Genzyme voluntarily recalled more than 12,000 distributed syringes of the 18,000 syringes in lot number 7RSL021 due to possible contamination. The syringes contained injectable arthritis gel used in an effort to alleviate pain and other symptoms of knee osteoarthritis.(3)
The syringes in this lot were linked to dozens of adverse events reported in the FDA Manufacturer and User Facility Device (MAUDE) database.(4)
In its notice to hospitals, physicians, and clinics, manufacturer Sanofi Genzyme said the syringes affected by the urgent voluntary Synvisc-One recall were distributed between October 25 and November 7, 2017. The company initiated the recall because “investigational testing revealed the presence of microbial contamination.”(5)
At that time, Sanofi Genzyme said its recall was “being conducted with the knowledge of the US Food and Drug Administration” and that is was “working with your distributors to ensure that all product in lot 7RSL021 is returned.”(6)
“Use of this recalled lot may result in a risk of infection and therefore, we are asking that you follow the required actions below to assist us in retrieving any remaining units of this voluntarily recalled lot.”(7)
Stop Using Contaminated Synvisc-One Arthritis Syringes
Sanofi Genzyme asked recipients of its notice to “Immediately discontinue use of the Synvisc-One lot number 7RSL021” and that “Health Care Professionals should treat their patients exposed to lot 7RSL021 in accordance with standard of care, being aware of the potential of a Gram negative infection.”(8)
On December 19, 2017, the recall was posted in the news section of the Sanofi company website. The page included contact numbers for doctors who had received contaminated syringes.(9)
One week before issuing its voluntary Synvisc-One injection recall, Sanofi Genzyme sent an urgent “product hold” notice to doctors, pharmacists, and clinics instructing them not to dispense or administer the medication. The manufacturer said that particular lot of Synvisc-One was linked to “an unexpected increase in the number of labelled adverse events…”(10)
The recalled Synvisc-One syringes were manufactured at Sanofi Genzyme’s plant in Ridgefield, New Jersey. These syringes were distributed in 36 states.(11)
Synvisc-One Injectable Arthritis Gel
Synvisc-One was approved by the U.S. Food and Drug Administration (FDA) in 2009. Sanofi Genzyme has noted that common Synvisc injection side effects include pain, redness, swelling, heat, and fluid build-up in or around the knee.(12)
The active ingredient in Synvisc-One is hyaluronan. The manufacturer extracts the hyaluronan from chicken combs. A chicken comb is the crest you see on top of a chicken’s head. You can also find hyaluronan in human joints.(13)
As an injected gel, Synvisc-One is used in an effort to lubricate and cushion the knee joint.(14)
Patients may receive this arthritis injection gel in an orthopedic surgeon’s or rheumatologist’s office. A typical injection is supposed to provide pain relief for up to six months.(15) (16)
In 2016, Synvisc-One generated more than $400 million in sales.(17)
FDA Issued Warning to Sanofi Genzyme
According to The Boston Globe, the FDA warned Genzyme in 2001 about manufacturing problems at the company’s plant in Ridgefield. At that time, Genzyme manufactured an earlier version of Synvisc.(18)
The FDA instructed Genzyme to address the problems at its manufacturing facility. Otherwise, it warned, the company could face severe consequences.(19)
The FDA also raised the concern that Genzyme had not demonstrated the company had adequately looked into complaints about its Synvisc gel.(20)
A report received by Synvisc-One’s manufacturer on December 8, 2017 describes a patient who required a joint aspiration and then surgery for her infection in an attempt to flush out the knee arthritis gel after receiving an injection from the recalled lot.
Synvisc-One Adverse Events Reported to FDA
Currently, the FDA’s MAUDE database provides descriptions of dozens of reports of adverse events linked to Sanofi Genzyme’s Synvisc-One recalled lot of contaminated injectable arthritis syringes.(21)
Some of the cases describe patients requiring outpatient treatment as a result of receiving a contaminated injection. Such treatments included fluid aspiration, cortisone injections, and corticosteroid or pain medication prescriptions. According to other reports, some patients visited an emergency room, required hospitalization, or both.(22)
A report received by Synvisc-One’s manufacturer on December 8, 2017 describes a patient who required a joint aspiration and then surgery for her infection in an attempt to flush out the knee arthritis gel after receiving an injection from the recalled lot.(23)
Another report describes a woman who received an injection from the recalled lot of Synvisc-One who was diagnosed with “pseudo-sepsis” requiring several days of treatment in the hospital.(24)
Common concerns include a patient’s inability to walk or bear weight. Other adverse events include:(25)
- Severe pain
- Decreased mobility
