Medical Device Lawyer investigates defective medical products & Zimmer Kinectiv Hip Injury Cases
Nationwide Success

Zimmer Hip Implant Attorney

investigating zimmer kinectiv hip complications

Zimmer-Biomet has been manufacturing and distributing hip replacement systems for many years, benefiting thousands of recipients. However, thousands of other patients have allegedly suffered injuries due to Zimmer products, and face painful revision surgery, infection, toxic reactions and permanent nerve damage.

Total hip replacement systems usually consists of four separate components, including a femoral stem, femoral head, liner and an acetabular shell. Each component has the potential to fail, and cause injury.

In 2003, Zimmer received FDA approval to market the M/L Taper Hip Prosthesis, and later in 2007, Zimmer received approval to market the Taper Hip Prosthesis with Kinectiv Technology, without a great deal of pre-market testing.

Now lawsuits and plaintiffs and their Zimmer Kinectiv hip recall lawyer allege the M/L Taper and Kinectiv hip products contained design and manufacturing defects.

Plaintiffs and medical device experts claim the taper of the stems and the femoral head cause fretting and corrosion, resulting in infection and metallosis. Recipients of these Zimmer hip implants may request tests from their doctors to check cobalt and chromium levels in the blood.

Joe Lyon is an experienced Ohio product liability attorney and Zimmer Kinectiv Hip Recall Lawyer investigating Zimmer Biomet recalls and hip replacement injuries for plaintiffs nationwide.

The Lyon Firm works with medical device experts to determine the root cause of injury and to build the strongest legal claim possible against medical device companies like Wright Medical, Zimmer Biomet, Smith and Nephew, Depuy and Stryker.

Zimmer Kinectiv M/L Stem Recall

After being on the market for less than one month, in June 2015 the FDA announced a Class 1 recall for the Zimmer M/L Taper with Kinectiv Technology. The Kinectiv technology was meant to allow a surgeon to adjust the length of the affected leg, relieve nerve issues, and allow a better range of motion and stability. However, the recall announcement stated that Zimmer found a higher-than-expected amount of manufacturing “residue” on the hip implant products.

Common complications of implant corrosion and metal debris discharge into the bloodstream were noted. Metallosis and revision surgery are major risk factors with hip implants, and may lead to permanent injury.

Metal Toxicity & Hip Replacement Injury

  • Infection of the joint
  • Sepsis—blood infection
  • Changes in hearing or vision
  • Tissue necrosis—death of tissue surrounding the joint
  • Nerve damage
  • Damage to the thyroid gland
  • Kidney disease or renal failure

Zimmer Kinectiv Hip Recall Lawyer

Due to manufacturing negligence, and putting profit before safety, medical device recalls have been more common now than ever. But instead of placing products in pre-market trials and requiring more clinical research, medical device companies bypass consumer safety, and put thousands of patients at risk.

Zimmer’s kinectiv M/L stem hip recall is just one of many device recalls.

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 Cincinnati product liability lawyer

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.



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.



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.
