Defective Knee Implants Attorney

investigating knee replacement failure cases

Following an unusually high rate of medical device failure, a few outcomes are likely to result: recipients are likely to suffer injuries related to a specific instrument, device recalls are likely to be issued by the Food and Drug Administration (FDA), victims and experienced product liability attorneys may file claims against a manufacturer, and knee implants lawsuits are likely to be settled or successfully tried in court if there is strong evidence to warrant the legal action in the first place.

This is exactly what the timeline of events looks like for many knee replacement systems made by Braun, Zimmer, Arthrex and Exactech. For patients implanted with the defective device, it may be time to contact a  knee implant defect lawyer. Thousands of knee implant patients have suffered debilitating injuries like infection, metallosis, joint pain and deformity, surrounding tissue damage, and resulting revision surgery.

Injured plaintiffs and your lawyer argue that defective knee implants, approved by the FDA, and part of the new generation of knee implants designed to last longer than the previously touted 15-year life span, present unnecessary health risks to consumers.

Moreover, doctors and patients were not aware of the hazards before deciding to accept defective knee implants rather than another alternative on the market. The FDA has received over a thousand reports of knee implants failing, and many were serious enough to require revision surgery.

Joe Lyon is a highly-rated Ohio Product Liability Attorney representing plaintiffs nationwide in a wide variety of defective medical device and civil litigation claims. 

Defective Knee Implants 

Since millions of patients are implanted with knee replacements, the situation is such that now scores of injured Ohio consumers have filed knee implant defect lawsuits, alleging Arthrex and Exactech are responsible for their pain and suffering, past and future medical expenses, and punitive damages for releasing, selling and distributing a dangerous product to the American public. Knee replacement failures may lead to a lawsuit and serious complications that can include:

  • Chronic pain
  • Bone Loss or fracture
  • Infection
  • Inflammation
  • Decreased range of motion
  • Tissue Damage
  • Metallosis
  • Revision Surgery

Knee Implants Settlements

Premature knee device failures and complications from Arthrex and Exactech replacement systems are far from uncommon. Implanting surgeons in Ohio are shocked to find a lack of cement bonding to the underside of the tibial tray, infection and and loss of tissue.

Injured plaintiffs in Ohio and around the country may contact an attorney to review a medical device defect case, and determine what compensation may be sought.

Questions about Defective Medical Device Litigation

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.

Our Victories

The Lyon Firm aggressively, professionally, and passionately advocates for injured individuals and families against companies due to a defective product or recalled product to obtain just compensation under the law. 

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.
