Fast Facts:

  • Stryker has paid more than $2 billion to settle Rejuvenated and AGB II hip replacement lawsuits.
  • There are currently more than 4,000 lawsuits filed over Stryker’s LFIT V40 femoral heads.
  • Hundreds more LFIT V40 lawsuits are expected to be filed before the first trial in 2019.

More than 3,400 people sued Stryker after problems with its Rejuvenate and AGB II hip led the company to pull the implants off the market. The company settled lawsuits over the devices in 2014. Less than two years later, the company recalled 42,000 other implants, triggering a new wave of lawsuits against the company.

Status of Stryker Hip Lawsuits and Settlements

Stryker has paid nearly $2 billion to settle thousands of lawsuits over its Rejuvenate and AGB II hip implants. The deadline to file a lawsuit under the settlement was March 2017. Stryker expected all settlement payments to be delivered by the end of 2017. As of November 2017, more than 1,800 lawsuits were still pending in a Minnesota federal court.

Meanwhile, lawsuits over the company’s LFIT V40 femoral head hip components are still being filed. Those cases are still in the early stages and hundreds more lawsuits over the devices could be filed before the first trial expected in late 2019.

As of November 2017, at least 83 lawsuits over the LFIT V40 had been combined in New Jersey state courts as a multicounty litigation (MCL). Another 131 lawsuits from across the U.S. had been combined in a Minnesota federal court as a multidistrict litigation (MDL). MDLs and MCLs allow several similar lawsuits to be consolidated to pool resources, reduce duplication and move cases more quickly through the courts.

Why People Sued Over Stryker Hip Replacements

People who sued Stryker over faulty hip implants claimed their devices caused severe pain and other complications that required additional surgery to repair.

Reasons Why People Sued Over Stryker Hip Implants

  • Branko Obradovic filed a lawsuit after he required revision surgery less than two years after receiving a Stryker hip replacement. He told the Palm Beach Post that he couldn’t sit for long periods of time and getting out of a car was an ordeal. “I’m very angry about the whole thing,” Obradovic said in 2013. “They should know what they are putting in someone’s body.”
  • Dianne Pingel of Boca Raton, Florida, filed the first lawsuit in the U.S. over Stryker’s Rejuvenate implants. She received two faulty hip implants in 2011, but by early 2013, she had undergone three revision surgeries to correct problems.
  • Tracy Sponer of North Little Rock, Arkansas, had her Stryker Rejuvenate hip implanted on Sept. 6, 2011. A year later, she was forced to have revision surgery after the hip failed. In her lawsuit, Sponer claimed the failure and revision surgery caused her ongoing mental and physical pain.
  • Mern Direnzo had the Accolade TMZF and LFIT Anatomic V40 Femoral Head implanted in October 2009. Blood tests showed high levels of metal ions in her blood and urine. She underwent a revision surgery to remove the device.
“[Stryker] failed to adequately design and manufacture the device to insure that it would not fret, corrode, erode, deteriorate and induce severe metal toxicity in patients,”

Accusations Against Stryker in Hip Implant Lawsuits

Stryker Hip Replacement Class Action Lawsuits

There are currently no class-action lawsuits over Stryker hip implants. The lawsuits over the LFIT V40 implants are primarily in either the multicounty litigation in New Jersey or the multidistrict litigation in Massachusetts.

MCLs and MDLs provide some of the same benefits as class-action lawsuits such as allowing people to pool their resources in court. But there are significant differences.

Differences Between Class Action Lawsuits and MDLs

Class Action Lawsuits Multidistrict Litigation (MDL)
A single lawsuit filed by an individual or small group on behalf of a large group of people Made up of several (even thousands) of individual lawsuits originally filed in multiple courts around the U.S.
Lawsuit undergoes “class certification” in which a court rules whether the case can be a class action A federal panel determines whether lawsuits can be combined in a single multidistrict litigation
Filed in either state or federal court Can only be filed federal courts (Some states allow MCLs or similar consolidation in state courts)
People taking part must have suffered the same injuries Injuries may be similar but do not have to be exactly the same
Can be filed for damages so small they would not be worth pursuing in individual lawsuits Individual awards or settlements can be quite large, hundreds of thousands of dollars in some cases
All parties receive a proportionate share of any award or settlement Awards and settlements can be tailored to each individual’s particular injuries

Stryker Sent Out Safety Warnings Over Defective Hip Implants

In July 2012, Stryker issued an Urgent Field Safety Notice about problems with its Rejuvenate and AGB II hip implants. The company warned that “fretting and/or corrosion” could lead to “metallosis, necrosis, and/or pain” for people implanted with the devices.

The company immediately withdrew both products from the market.

Stryker issued another notice for certain LFIT V40 Femoral Heads in August 2016, citing taper lock failure. The notice listed “potential hazards” that could occur with the recalled devices. These included “excessive metallic debris,” which has been associated with metallosis in other hip implants.

Potential Hazards of Recalled LFIT V40 Femoral Heads

  • Disassociation of femoral head from hip stem
  • Fractured hip stem trunnion
  • Excessive metallic debris
  • Insufficient ROM
  • Insufficient soft tissue tension
  • Noise
  • Loss of implant: bone fixation strength
  • Excessive wear debris (polymeric)
  • Implant construct with a shortened neck length

In another notice seven months later, the company repeated that doctors did not need to change their follow-up procedures, but suggested they be alert for possible symptoms that could mean serious complications resulting from LFIT V40 implants.

“Complaints of new or continued pain, stiffness, instability or swelling in the hip, groin, buttock or thigh warrant further investigation.”

Stryker advised doctors to consider lab tests for patients already implanted with the recalled devices if they showed symptoms of possible complications.
