Arthrex iBalance Injury Lawsuits

investigating knee replacement complications

In February, 2016, the U.S. Food and Drug Administration (FDA) announced a recall for the Arthrex iBalance knee replacement device due to issues with a defective tibial tray causing loosening and implant failure. The FDA said almost 2,400 Arthrex iBalance units were affected by recall which may have been implanted in patients across the U.S.

Following the knee replacement recall, Arthrex stated that the devices “reported to have a smooth texture to the outer surface of the metal, which differed from a previous that had a textured outer surface.” In short, the device is defective and incompatible with other knee replacement components. The result is a number of patients with a defective device implanted in their knee, which is likely to fail and cause serious complications.

Patients may need revision surgery if their implant Arthrex iBalance knee replacement fails or loosens. The most common sign of failure is knee pain or knee instability, often the result of poor bonding between the metal implant and the knee.

Failing Arthrex Device Lawsuits

The Arthrex iBalance Tibial Tray is part of the Arthrex iBalance Total Knee Arthroplasty System. It was created for the purpose of treating multi-compartmental knee cartilage degeneration caused by osteoarthritis or post-traumatic arthrosis. Arthrex marketed the iBalance as an alternative to other total knee replacements, and it is meant to reduce the need for later surgeries to have metal plates and screws removed.

However, patients are finding out that because there are issues with Arthrex knee replacement devices, the potential complications make it necessary to have a revision surgery.

So although the Arthrex iBalance implant was originally intended to reduce the need for further operations, patients must undergo additional surgeries in the end. Knee replacement patients who require additional surgeries face an increased risk of post-op infection, tissue damage, nerve damage, bone loss and other complications.

Patients also face time away from work and lost wages, as well as a painful recovery and rehab period. Compensation for medical costs and other damages can be recovered by filing a claim against a negligent manufacturer of a defective medical device.

Arthrex iBalance Device Failure

  •  Chronic Pain—some level of pain is normal after an implant operation, but if the pain continues or worsens, and you notice a constant throbbing, you could be suffering from a defective device.
  • Inflammation—knee ligaments and surrounding tissue may become inflamed when a defective knee device causes friction. This results in a build-up of fluid, swelling and further immobility.
  • Instability—if you stand or walk and notice an unstable knee soon after a knee device has been implanted, you may be experiencing a defective product.
  • Implant Loosening & Fracture—patients have reported that they can feel when knee implant components are loose or detached.
  • Warmth felt in Knee—abnormal sensations following surgery are common, but if you feel warmth or heat in your knee months later, this may be a sign of a failed knee implant.
  • Bone Fracture—device failure can lead to structural damage like a bone fracture if a defective knee system puts too much pressure on the knee.
  • Failure to Bond—implants may detach from the bone when defects are present.
  • Mobility Issues—if you notice a decreased range of knee motion in the weeks or months following a knee replacement, the device may not be functioning as intended.
  • Revision Surgery—when a defective device is implanted and begins to cause problems, it will require a revision surgery to remove and replace the faulty components.
  • Other Serious Complications—Defective knee replacement systems can lead to complications like blood clots, bone loss, tissue damage, nerve damage, infections, and metallosis.

Questions about Defective Medical Devices
How is a Medical Device Defined as Defective?

Ohio Definition of Defective

Under Ohio law, a medical device is  defective if it is unreasonably dangerous for its intended use. A legal cause of action can be based on several types of medical device product defects. Most jurisdictions a version of one or more of these cause of actions. 

(1)  Manufacturing/ Construction Defect of the medical device:

(2) Defective design and/or formulation of the medical device:

(3) Failure to warn or inadequate warning or instruction associated with the medical device:

(4) Misrepresentation on the Safety or Efficacy of the Medical Device:

(5) Fraud Related to the Safety or Efficacy of the Medical Device

(6) Negligent Distribution or Testing of the Medical Device

How do you prove design defect in a medical device lawsuit?

Defective design medical device cases arise not because a mistake was made during the manufacturing process, but rather the original design of the product is unreasonably dangerous. A “risk-benefit analysis” is used to determine whether safer/less expensive alternative designs were available to the manufacturer (e.g. the metal on metal design, the porosity and stiffness of transvaginal mesh )

For these claims, the FDA Review process is critical on whether a pre-emption defense exists.  For devices that went through the PMA (pre-market approval process), rather than the 510K process, the case must be evaluated very carefully for any parallel claims under state and federal regulations (e.g., failure to warn or failure to disclose adverse events) that can advance the case forward.  Without a careful legal analysis, the case may be subject to dismissal even where the medical device design proves to be defective. 

Risks:  The following factors are considered under Ohio law when determining the risks associated with the design of a medical device:  (1) the magnitude of the risk of injury; (2) ordinary consumer awareness of the risk for injury; (3) the likelihood of causing injury; (4) the violation of a private or public standard; and (5) the consumer’s expectation of the performance of the product and level of danger. Ohio Revised Code 2307.5 (B) Product Defective in Design or Formulation. These factors are considered in most other jurisdictions. 

BenefitsThe following factors are considered under Ohio law when determining the benefits associated with a medical device: (1) the utility of the product; (2) availability of an alternative design; (3) the magnitude of risks associated with an alternative design. Ohio Revised Code 2307.5 (c) These factors are considered in most other jurisdictions. 

Defenses for Defective Design(1) a pharmaceutical drug or medical device is not defective by design if it contains an adequate warning of an unavoidably unsafe aspect of the pharmaceutical or medical device; (2) the dangerous aspect is inherent to the product, recognizable, and cannot be eliminated without compromising the product’s usefulness; (3) a lack of a feasible alternative design. 2307.75 (d)(e)(f).

What is a manufacturing defect in a medical device lawsuit?

A manufacturing defect claim arises where the medical device is released from the factory in a manner that deviates from the intended design or specifications. 

Most manufacturing defect cases are based on a products deviation from the intended specification, formula, performance standards, or design model. In such cases, it may be easy to determine the product did not comply with the intended design. In defective medical device cases, the manufacturing defect is often related to performance standards (e.g., the metal does not meet the strength specification or has microscopic fractures–these defects require an examination by a qualified metallurgist who can examine the medical device).

As a result of the deviation, the product enters the market in an unreasonably dangerous condition and the consumer is exposed to or purchases a product that is defective. Any personal injuries or economic loss that arise from the the defect are compensable under Ohio product liability law.

The product may be recalled as a specific lot is identified as being non-compliant and defective. A product may be defective in manufacture or construction, materials and assembly, and a manufacturer or distributor may be subject to strict liability, even though it exercised all possible care.  Ohio Revised Code 2307.74.


What is a failure to warn claim in a medical device lawsuit?

All medical device products come with  warnings and instructions for use that are provided to the physician. If the company does not provide the physician with all the relevant safety data so that the physician adequately understand the risks and benefits of the product, then the medical device is defective. 

The physician must be in a position to pass the appropriate safety data onto the patient, so the patient can make an informed decision on whether they wish to have the medical device implanted.  Patient informed consent is critical because many devices are designed to be permanent.  

Litigation arises where there is evidence the medical device manufacturer failed to timely update a warning in light of new data or simply ignored the risk and failed to conduct sufficient research to identify and then disclose the risk.

In determining whether a medical device is defective due to inadequate warning or instruction, evidence must be presented to prove:

  • The medical device manufacturer knew, or in the exercise of reasonable care, should have known about a risk
  • A reasonable medical device manufacturer would have provided a warning of the risk
  • The medical device manufacturer failed to provide the warning
  • The patient was injured due to a lack of warning. The same elements apply whether the claim is based on a warning present during the marketing or post-sale warnings.

Defenses to Failure to Warn Claims(1) the risk was open and obvious or a matter of common knowledge; and (2) in cases of a pharmaceutical drug or medical device, the warning was provided to the prescribing physician (“Learned Intermediary Doctrine”).

What government agency regulates the recall of a medical device?

Design and manufacturing defects result in medical device product recalls each year in the United States, initiated by federal safety agencies.

  • The Food and Drug Administration (FDA)
  • The Consumer Product Safety Commission (CPSC)

The foregoing listed government agencies may initiate recalls of dangerous products but do not provide remedies or compensation for damages where an individual is injured due to the defective product. Only litigation can utilized to compensate patients injured by a defective medical device.

Your Right to Safety

Watch our Video About the Process

Defective products on the market present safety and health hazards for adults and children. Cheap and defective products may pose fire and burn risks; electrocution, strangulation and choking risks; and severe health risks. The manufacturers of consumer products have a duty to foresee potential injury and properly design and test products before they are released.

Companies must also properly warn consumers of any risks associated with their products. Any failure to protect consumers that results in accidents and injury can lead to lawsuits filed by plaintiffs and their product liability lawyer.

IN RE: DEPUY ASR

METAL ON METAL HIP IMPLANTS

Nationwide Consolidation in U.S. District Court, Northern District of Ohio. The Depuy ASR Hip design was plagued with problems related to premature loosening and metallosis, caused by chromium and cobalt entering the blood stream. The resulting injuries were a result of the metal-on-metal friction inherent with the design of the product. Depuy recalled the ASR and entered into a global settlement valued at $2.5 Billion to cover an estimated 8,000 patients. The Lyon Firm represented several clients in the original settlement and continues to be active in this litigation. The settlement funds provided compensation for the revision surgeries, including compensating for medical costs, lost wages, and pain and suffering.

IN RE: BIOMET MSA MAGNUM

METAL ON METAL HIP IMPLANTS

Nationwide Consolidation in U.S District Court, Northern District of Indiana. Similar to the Depuy ASR, the Biomet metal-on-metal hip design allegedly contributed to premature hip failures and metallosis due to the metal friction. Biomet entered into a global settlement valued at $56 million to cover a few thousand claims. The Lyon Firm represented several plaintiffs in the original settlement and continues to be active in this litigation.
