NexGen Knee Implant Recall & Dangerous Medical Device Claims

If you had knee replacement surgery and have received a NexGen knee implant and had to undergo revision surgery due to problems including: loosening of the implant, pain, infection, or difficulty walking, you may have important legal rights. There is currently a limited NexGen knee recall for a specific tibial component. According to some patients and critics, there have been problems related to the Zimmer NexGen replacement.

In September 2010, Zimmer, Inc. announced a recall of a specific tibial component of its NexGen knee implant. This Zimmer NexGen recall applies only to a specific component. Some research has revealed a higher-than-acceptable failure rate with the Zimmer knee, and some doctors have expressed the view that there should be a general recall of the Zimmer NexGen knee. It is estimated that since 2003, the NexGen knee replacement has been implanted in more than 150,000 patients. This potential recall would only affect a relatively small number of patients who had knee surgery since 2003 and in whom the recalled tibial plate was used. Some patients have already reported experiencing knee implant problems, including: serious or ongoing pain, infection, swelling, and loosening or dislocation of the implant.

Common Risks Associated With Knee Replacement Surgery

Knee replacement is usually successful in most people who have it. When problems do occur, most are treatable. Possible problems include:

• Infection – Areas in the wound or around the new joint may get infected. It may happen while you’re still in the hospital or after you go home. It may even occur years later. Minor infections in the wound are usually treated with drugs. Deep infections may need a second operation to treat the infection or replace the joint.
• Blood Clots – If your blood moves too slowly, it may begin to form lumps of blood parts called clots. If pain and swelling develop in your legs after hip or knee surgery, blood clots may be the cause. The doctor may suggest drugs to make your blood thin or special stockings, exercises, or boots to help your blood move faster. If swelling, redness, or pain occurs in your leg after you leave the hospital, contact your doctor right away.
• Loosening – The new joint may loosen, causing pain. If the loosening is bad, you may need another operation. New ways to attach the joint to the bone should help.
• Dislocation – Sometimes after hip or other joint replacement, the ball of the prosthesis can come out of its socket. In most cases, the hip can be corrected without surgery. A brace may be worn for a while if a dislocation occurs.
• Wear – Some wear can be found in all joint replacements. Too much wear may help cause loosening. The doctor may need to operate again if the prosthesis comes loose. Sometimes the plastic can wear thin, and the doctor may just replace the plastic rather than the whole joint.
• Nerve and Blood Vessel Injury – Nerves near the replaced joint may be damaged during surgery, but this does not happen often. Over time, the damage often improves and may disappear. Blood vessels may also be injured.

If you experienced complications after receiving a NexGen implant, speaking with a Denver defective medical device attorney can help you understand your legal rights and potential compensation options.

GranuFlo® & NaturaLyte® Dialysis Product Lawsuits

Use of the dialysis products, GranuFlo® and NaturaLyte®, has been linked to an up to six-fold increase in the risk of cardiopulmonary arrest and sudden cardiac death. The manufacturer, Fresenius Medical Care (FMC), was aware of the injuries and dangers associated with their dialysis products but failed to warn patients and doctors until 2012. The result has placed more than half of all dialysis patients in the United States at risk and set the stage for imminent GranuFlo lawsuits.

Learn how:

• FMC officials decided to hide, mislead, and obscure information about patient safety hazards in order to maintain their market share, putting profits ahead of patients’ safety!
• The company’s slow response placed more dialysis patients at risk, even though evidence was crystal clear: high pre-dialysis serum bicarbonate levels created a risk of cardiac arrest and death.
• Despite patient safety issues and potential GranuFlo lawsuits, Fresenius Medical Care continues to aggressively market the products and routinely bundles GranuFlo and/or NaturaLyte with other FMC products for pricing discounts.
• You, and your loved ones may have suffered-or are currently still at risk! It is estimated that 3,300 dialysis clinics, servicing approximately 260,000 dialysis patients, are currently using these potentially harmful formulations.

Study Findings and Reported Deaths

On March 29, 2012, the U.S. Food and Drug Administration (FDA) issued a Class 1 recall of GranuFlo and NaturaLyte, dialysis products manufactured by Fresenius Medical Care. The use of either product can result in high bicarbonate levels that can cause metabolic alkalosis, a significant risk associated with low blood pressure, hypokalemia, hypoxemia, hypercapnia, and cardiac arrhythmia, which may culminate in cardiopulmonary arrest and death.

Class 1 recalls are the most serious type of recall and involve situations in which there is a reasonable probability that use of these products will cause adverse health consequences or death.

Research Behind Serious Recall

Medical research links GranuFlo® and NaturaLyte® to high bicarbonate levels that can cause a variety of health problems, including:

The GranuFlo® and NaturaLyte® recall states that the company failed to disclose vital information to the FDA and health-care providers about the possible risk of high bicarbonate levels when administering these products.

Cardiac death is recognized as the number one cause of death for dialysis patients, accounting for 59% of those deaths. By 2010, the medical community had concluded that these cardiovascular-related deaths were not due primarily to atherosclerotic (plaques and arterial stiffening) disease, but rather uremic cardiomyopathy, characterized by left ventricular hypertrophy (LVH), LV dysfunction, and LV dilatation. This conclusion caused many in the medical community, including FMC, to research the issue, possibly a little too late to prevent GranuFlo® and NaturaLyte® related injuries.

Risks and Side-Effects

There are currently more than 5,700 dialysis centers serving approximately 400,000 dialysis patients in the United States. FMC, the largest dialysis services and products company in the U.S. and the world, not only owns thousands of dialysis clinics, but it also manufactures nearly all the medical products used in dialysis care.

GranuFlo is an acid concentrate powder product that allows dialysis clinics to mix their own acid concentrate solutions, which helps lower shipping costs and storage space associated with traditional 55-gallon drums. Its formulations are the only marketed products to contain the “dry” powder form of acetic acid, sodium diacetate. Because GranuFlo uses sodium diacetate, it doubles the acetate concentration in dialysate compared to formulations made with acetic acid. FMC also sells traditional, pre-mixed, liquid acid concentrate formulations under the brand name NaturaLyte.

Company Sat On Crucial Information

In response to the high rate of cardiac arrests that occurred in Fresenius Medical Care clinics in 2010, the company submitted an internal memo to its own dialysis clinics on November 4, 2011.

After the FDA received an anonymous copy of the November 4th internal memo, company executives were forced to issue an urgent public product warning and recall to its customers, stating that GranuFlo and NaturaLyte were associated with elevated bicarbonate levels and an increased risk of cardiopulmonary arrest and sudden cardiac death.

Studies Show 941 Deaths

FMC conducted a case-control study evaluating risk factors among hemodialysis patients who suffered cardiopulmonary arrest in FMC facilities, compared with other dialysis patients within the same facilities, between January 1 and December 31, 2010. This study identified 941 patients across 667 FMC facilities who experienced cardiopulmonary (CP) arrests within those facilities. Looking at the data for these 941 patients, the study found that the patients’ risk of cardiopulmonary arrest was up to six times higher if they had an elevated pre-dialysis bicarbonate level.

According to the memo, FMC was aware that there was a significantly increased risk of cardiac arrest and death during hemodialysis treatments associated with their GranuFlo and NaturaLyte dialysis concentrate products that contain sodium diacetate. The memo recommends action for patients with elevated pre-dialysis bicarbonate levels. However, FMC provided this memo only to its doctors and dialysis facilities, not to non-FMC physicians and clinics that were using the products, despite the fact that over 100,000 dialysis patients were receiving products at non-FMC facilities.

FMC only decided to share its knowledge with the thousands of non-FMC physicians and clinics on March 29, 2012, after a copy of the November 4, 2011, internal memo was leaked to the FDA. Even then, FMC did not share all of its information. What was provided was a scientifically ambiguous, two-page memo that lacked the details and the urgency of the FMC internal memo. A key point: the March 29 memo did not mention patient blood levels or the most at-risk population of all, “acute” dialysis patients, and only included one of ten medical references that the FMC internal memo did.
