Zimmer Biomet Holdings, the result of the June 2015 merger of Zimmer Holdings and Biomet, Inc., is a leading manufacturer of hip replacement products. Patients have experienced early failures with many Zimmer Biomet’s hip replacement devices, frequently requiring a major operation to correct the problem.

Zimmer Biomet Hip Replacement Injuries
Several Zimmer Biomet hip replacement device are known to cause serious injuries in patients or prematurely fail, requiring surgical replacement:
Zimmer Durom Cup Injuries
Many patients implanted with the Zimmer Durom Cup, a metal hip implant, have experienced negative side effects, including pain, metallosis when large amounts of metal wear particles enter the tissue surrounding the hip and the bloodstream, and premature loosening of the Zimmer Durom Acetabular Cup.
Over 12,000 patients in the United States were implanted with the Durom Cup when it was sold between 2006 and 2010. Patients implanted with Zimmer Durom Cup are at risk for early implant failure resulting from metal wear and loosening, and various sources estimate that at least 24% of patients who were implanted with the Durom Cup will be forced to undergo revision surgery due to implant failure.
A prominent joint registry (which tracks the performance of hip replacements) recently published results showing the Durom cup had a hazard ration of 3.15 – meaning the Durom Acetabular cup was more than three times as likely to fail as other better designed hip replacement products. Although Zimmer issued a hazard alert about the Durom cup in New Zealand in 2012, Zimmer has not recalled the Durom in the United States.
Biomet M2a Magnum and M2a-38 Hip Replacement Injuries
First released in 1996, the Biomet M2a Magnum and M2a-38 line of hip implants have a metal stem, a metal ball and a metal cup. Biomet claimed that these so-called metal-on-metal hip replacements would reduce wear, allowing patients to more readily resume an active lifestyle. Unfortunately, Biomet M2a hip replacements produce toxic cobalt metal debris that causes pain, tissue damage, metallosis, and adverse tissue reactions called pseudotumors. The consequences of the metal debris are that patients often need early revision surgery to remove and replace the Biomet hip implant.
In a study published in 2012, doctors studied 108 patients with Biomet’s M2a Magnum hip replacements and discovered that 39% of the patients developed pseudotumors in their hips about 3.6 years after implantation. The doctors also found that patients with elevated levels of toxic cobalt debris in their blood had a four times increased risk of developing a pseudotumor. Many of the patients with this adverse reaction to metal debris needed surgery to revise their hip replacements. The study also noted that pseudotumors can become painful and symptomatic up to 15 years after the implant operation, so patients with Biomet metal hip replacements should be closely monitored.
More recently, in February 2015, the Australian Department of Health required Biomet to issue a Hazard Alert warning patients that Biomet’s metal-on-metal M2a hip replacements had a higher than expected rate of failure, and that Biomet had agreed to stop selling these devices. The Australian National Joint Registry published its 2015 annual report citing the Biomet M2a cup and ball on a Biomet Taperloc stem as having a 13.3% failure rate at 10 years. Other total hip replacements typically have only a 5.5% failure rate after 10 years. This data indicates that Biomet M2a Magnum and M2a-38 hip replacements are much more dangerous than other hip replacements.
Zimmer M/L Taper with Kinectiv Technology Injuries
The Zimmer M/L Taper with Kinectiv technology, a femoral stem with an exchangeable neck, permits surgeons to choose between multiple femoral stems and necks to customize the hip implant for the patient. However, because the metal neck must be inserted into the metal stem as well as the metal femoral head, there are two metal to metal interfaces. As a result, the Zimmer M/L Taper stem and neck combination is more prone to movement (rocking or turning) and has a tendency to corrode and crack at these interfaces, causing metallosis, production of metal ions, or potentially a catastrophic fracture.
Since the Zimmer M/L Taper with Kinectiv technology was first approved in 2007, multiple Adverse Event Reports have been filed with the FDA alleging that Zimmer M/L Taper hip implants have corroded and caused pain, infection, and metallosis in patients. Recently, a prominent international joint registry listed the Zimmer M/L Taper Kinectiv fermoral stem as have a higher than expected failure rate, but noted that Zimmer continues to sell the device.
Symptoms of Zimmer Biomet Hip Implant Injuries
If you have a Zimmer Biomet hip replacement and suffer the following injuries and symptoms, you may have a claim for compensation:
- Need a second surgery to replace your Zimmer Biomet hip implant;
- Suffer from groin pain, hip pain, infection, or inflammation;
- Have clicking, popping, grinding or squeaking noises coming from your hip replacement;
- Suffer a partial or complete dislocation of your hip replacement;
- Have metallosis or high levels of cobalt and chromium metals in your blood;
- Your hip replacement becomes loose;
- You have a pseudotumor.
Zimmer Biomet Hip Replacement Recalls
In addition to reports of corrosion, pain, infection, and metallosis, many Zimmer M/L Taper with Kinectiv technology hip replacements have been recalled. In June 2015, the FDA issued a class I recall for the Zimmer M/L Taper with Kinectiv Technology. These femoral stems and necks of the Zimmer M/L Taper with Kinectiv Technology were coated with high quantities of manufacturing residue that can cause allergic reaction, infections, pain, and even death. Sixty-four lots were recalled.
Zimmer Biomet Hip Replacement Settlement
Zimmer Biomet has settled with numerous Durom Cup patients for a total of over $400 million.
In January 2014, Biomet agreed to pay approximately $56 million to settle many of the M2a Magnum cases against it. The settlement paid up to $200,000 for each Biomet M2a hip replacement that was removed.
There Is Still Time to Obtain Compensation for a Defective Zimmer Biomet Hip Replacement
Patients implanted with defective Zimmer Biomet hip implants still have time to seek compensation for their injuries. The time to seek compensation is limited by the law, so do not delay in seeking advice.

Zimmer Biomet Hip Replacement Lawsuit & Settlement Updates
- $9.2 Million Zimmer Durom Hip Replacement Verdict – On July 24, 2015, a jury in Los Angeles awarded Gary Kline $9.2 million for injuries sustained due to a defective Zimmer hip replacement device with a Zimmer Durom Cup. After less than four hours of deliberation, the unanimous jury found Zimmer negligent in its design of the metal-on-metal Durom Cup. This was the first of 25 Durom Cup cases to be tried in Los Angeles County Superior Court.
- Defense Victory in Zimmer Durom Hip Replacement Suit – On August 7, 2015, a jury in Illinois cleared Zimmer of producing and selling a defective Durom Cup hip implant. Plaintiff Harold R. Mullin alleged failure to warn, design and manufacturing defects, and failure to test a coating on the implant, but the jury unanimously rejected each claim. This is the second Zimmer victory in St. Clair County, Illinois, after the company won another Durom Cup trial there in December 2014.
