Cartiva Lawsuit Explained: Recall, MDL 3172, Hydrogel

Last updated: October 2026

The Cartiva lawsuit is a group of product liability cases claiming that the Cartiva Synthetic Cartilage Implant, a hydrogel plug used to treat big toe arthritis, fails far more often than patients were told. After Stryker issued a recall notice in October 2024, the federal cases were combined in February 2026 into MDL No. 3172 in Arkansas. As of October 2026, the case is at an early stage and no settlement has been announced. Because the Cartiva lawsuit is still early, this guide also explains key legal terms, how to follow the case yourself and what it means if you still have the implant.

Here is a plain-language look at the device, the recall, the MDL and the central failure theory behind the claims.

What the Cartiva implant is

Cartiva is a small cylinder made of polyvinyl alcohol and saline, according to the FDA’s summary of safety and effectiveness. Surgeons press-fit it into the head of the first metatarsal, the bone at the base of the big toe. It was meant to cushion an arthritic joint while keeping it moving.

The FDA approved Cartiva on July 1, 2016. The approval was based on a trial called MOTION, which compared 152 Cartiva patients with 50 patients who had a fusion. At two years:

• About 79.8% of Cartiva patients and 78.7% of fusion patients met the study’s success measure.
• About 11.2% of Cartiva patients had another surgery, compared with 12% in the fusion group.
• Removal of the implant was the most common second procedure, at 9.2% of Cartiva patients.

Those results made Cartiva an appealing option for people who wanted to avoid fusing the joint.

The Cartiva recall

On October 31, 2024, Stryker, which owns Cartiva through Wright Medical, sent surgeons an urgent field safety notice. It said newly published data and post-market reports showed higher-than-expected rates of:

• Revision surgery and implant removal
• Subsidence, meaning the implant sinks into the bone
• Displacement, meaning it moves out of place
• Pain and nerve damage
• Fragmentation, meaning the implant breaks apart

The FDA’s recall database entry shows:

• Classification: Class 2
• Products: all sizes (6, 8, 10 and 12 mm)
• Distribution covered: July 2016 through October 2024
• Cause: device design
• Status: open

Surgeons were told to quarantine and return remaining implants and to keep watching patients for pain, stiffness, swelling and trouble walking. The recall did not tell patients without problems to have the implant removed.

MDL 3172: how the federal cases were combined

Some Cartiva lawsuits were filed before the recall. After it, more followed. On February 5, 2026, the Judicial Panel on Multidistrict Litigation created MDL No. 3172, titled In re: Cartiva Synthetic Cartilage Implant Products Liability Litigation.

• Court: U.S. District Court for the Eastern District of Arkansas
• Judge: Chief Judge Kristine G. Baker
• Defendants: Cartiva, Inc. and its corporate successor, Wright Medical Group N.V.
• Why Arkansas: the panel said key evidence and witnesses are likely near Memphis, Tennessee, where Wright Medical was based
• Case count: 21 pending cases as of the JPML’s September 1, 2026 report

Cartiva opposed combining the cases, but the panel found the claims shared common questions about design, testing, marketing and the recall.

An MDL is not a class action

In an MDL, each person keeps an individual case. One judge handles shared pretrial work such as document exchange and rulings on scientific evidence. Each claim is still judged on its own medical facts.

The hydrogel failure theory

At the heart of the Cartiva lawsuit is a claim about the material and design of the implant itself. According to the plaintiffs, a soft hydrogel plug held in place by a press fit does not stand up well to the forces of walking over time.

What plaintiffs allege

Based on the complaints described by the panel, plaintiffs say the implant:

• Sinks into the metatarsal bone
• Shifts or migrates out of position
• Breaks down or fragments
• Leads to bone loss, swelling, pain and loss of mobility
• Ends up requiring more surgery, often a fusion

How the legal claims are framed

The complaints generally raise three kinds of claims:

• Design defect: the product was unreasonably dangerous as designed.
• Negligence and failure to warn: the company did not use reasonable care in testing or warning about failure rates.
• Breach of warranty: the implant did not perform as promised.

A key question will be what the company knew, and when, about failure rates that the recall notice says were higher than in the approval study.

What the defense may argue

Cartiva went through the FDA’s premarket approval process. Defendants in cases involving these devices often argue that federal law blocks many state-law claims. How the court handles that issue could shape the case. For more on how that compares with past device litigation, see what past device cases predict for Cartiva.

Cartiva lawsuit timeline

Putting the key dates in order shows how quickly the case has moved since the recall:

• July 1, 2016: FDA approves the Cartiva implant
• October 31, 2024: Stryker sends its urgent field safety notice to surgeons
• December 4, 2024: FDA posts the recall as Class 2
• February 5, 2026: federal cases combined into MDL No. 3172
• February to June 2026: more cases transferred into the MDL
• August 26, 2026: initial organizational meeting set by the court

If you had your implant placed or removed during this period, these dates can help you and a law firm see where your own timeline fits. They may also matter for filing deadlines, since some states look at when a person learned a device could be the cause.

What happens next in the Cartiva lawsuit

The court’s MDL 3172 page lists transfer orders through June 2026 and a first organizational meeting set for August 26, 2026. Typical next steps in an MDL include:

• Appointing lead attorneys for the plaintiffs
• Setting a schedule for document exchange and depositions
• Creating rules for filing new cases directly in the MDL
• Choosing bellwether cases for early trials

None of these steps promises a settlement. They set the pace for the years ahead.

Key Terms in the Cartiva Lawsuit

News about the Cartiva lawsuit is full of legal shorthand. This plain-language glossary can help you follow court updates and talk with a law firm.

Terms about the device

• Premarket approval (PMA): the FDA’s strictest review path for high-risk devices. Cartiva was approved through this process in 2016.
• Field safety notice: a letter a company sends to doctors and hospitals about a safety issue. Stryker’s October 2024 notice started the recall.
• Class 2 recall: the FDA’s middle risk level for a recall. It covers products that may cause temporary or reversible health problems, or where the chance of serious harm is remote.

Terms about the court process

• Multidistrict litigation (MDL): a way to send similar federal cases to one judge for pretrial work. Each case stays separate.
• Transferee judge: the judge who handles the MDL. In the Cartiva lawsuit, that is Chief Judge Kristine G. Baker.
• Conditional transfer order (CTO): an order that sends newly filed related cases into the MDL. The court’s MDL page lists six of these, from February 6 through June 24, 2026.
• Plaintiff fact sheet: a detailed questionnaire many MDLs require each plaintiff to complete.
• Discovery: the stage where both sides exchange documents and take sworn testimony.
• Rulings on scientific evidence: decisions on whether testimony about science and medicine meets the federal standard, often called Rule 702 rulings.
• Bellwether trial: an early test trial of a selected case that can help both sides judge how others might go.

Terms about deadlines

• Statute of limitations: the deadline to file a lawsuit. It varies by state and claim type.
• Discovery rule: a rule in some states that starts the clock when a person learned, or should have learned, of an injury and its possible cause.
• Statute of repose: a firm cutoff in some states that can apply no matter when the injury was found.

How to Follow the Cartiva Lawsuit Yourself

You do not have to rely on ads or social media for updates. Several free or low-cost public sources show what is actually happening.

Where to look

• The court’s page: the Eastern District of Arkansas MDL 3172 page posts the transfer order, conditional transfer orders and key scheduling letters.
• The Judicial Panel on Multidistrict Litigation: the JPML publishes regular reports that list how many cases are pending in each MDL.
• PACER: the federal court records system lets anyone search dockets. It charges small per-page fees, though many users pay little or nothing each quarter.
• The FDA recall database: the recall entry shows the classification, products covered and current status.

What to watch for next

Court filings in the coming months may include orders naming lead lawyers for the plaintiffs, case management orders that set schedules, and rules for filing new cases directly in the MDL. Each of these shapes the pace of the Cartiva lawsuit.

Be careful with claims you see online

Some ads talk about “payouts” or “settlement amounts” before any settlement exists. As of October 2026, no Cartiva settlement had been announced. Treat any dollar figure you see with caution, and check the court’s own page when in doubt.

Watch out for pressure and scams

• Be wary of anyone who calls, texts or emails you out of the blue about the Cartiva lawsuit.
• Do not pay anyone up front to “sign you up” for a settlement. Joining a case does not work that way.
• Never share your Social Security number or bank details with someone you have not checked out.
• You can confirm that a lawyer is licensed by searching your state bar’s public lookup tool.

If something feels rushed or too good to be true, slow down. A legitimate firm will give you time to read and ask questions.

What the Cartiva Lawsuit Means If You Still Have the Implant

Many people with a Cartiva implant feel fine. Others are not sure whether their aches are normal. The Cartiva lawsuit does not change your medical choices, but it is a good reason to stay alert.

Keep up with checkups

Stryker’s notice asked surgeons to keep monitoring patients. It did not tell patients without problems to have the implant removed. Talk with your surgeon about how often you should be seen and whether new X-rays make sense.

Know the warning signs

Returning pain, swelling, stiffness, numbness or trouble walking are all worth reporting. If imaging shows the implant has sunk or moved, ask for a copy of the report.

Report problems

Patients can report device problems to the FDA through MedWatch, online or by mail, according to the FDA’s reporting page. Keep a copy of anything you send.

Save your paperwork now

Even if you have no symptoms, keep your operative report, implant record and any recall letter in a safe place. If problems appear later, these records help your doctor and any firm reviewing a possible Cartiva lawsuit claim.

Think about timing

In some states, the filing clock may start once you knew, or should have known, that the implant might be causing harm. If you have symptoms, it can help to ask a firm about your dates sooner rather than later.

If you help a parent or partner

Many Cartiva patients rely on a spouse, adult child or friend to help with appointments and paperwork. If that is you, ask the patient to sign a records release so you can request documents on their behalf.

Keep notes of what you see day to day, such as limping, missed activities or extra help at home. Those details can fill in gaps that medical records leave out.

Build Your Own Cartiva Lawsuit Timeline

Dates are at the center of almost every device case. A simple personal timeline helps your doctor follow your care and helps a firm check deadlines. It also lets you see how your story lines up with the public Cartiva lawsuit timeline.

Dates to write down

1. The date your Cartiva implant was placed, and in which foot
2. The first time you noticed new or returning pain, swelling or stiffness
3. The date you received a recall letter or first heard about the recall
4. Each visit where you reported a problem to a doctor
5. The first X-ray or scan that showed the implant had sunk, moved or broken
6. The date of any revision, removal or fusion surgery
7. The date you first wondered whether the implant itself caused your problems

Why each date matters

The surgery date helps confirm whether your implant falls inside the recall period of July 2016 through October 2024. Symptom and imaging dates show how the problem developed over time.

The last date on the list can matter a great deal. In states that follow a discovery rule, the filing clock may start around the time a person learned of a possible link. That is why it is better to write down the truth, even if it feels unclear, than to guess.

Keep it simple and honest

Use your calendar, patient portal and pharmacy records to fill in gaps. If you are unsure of an exact day, note the month and year and say it is an estimate. A clear, honest timeline is one of the most useful things you can bring to a Cartiva lawsuit review.

Questions to Ask Before Joining the Cartiva Lawsuit

If a participating law firm offers to help, these questions can help you understand how your case would be handled.

About where your case goes

• Will my case be filed in the federal MDL or in a state court, and why?
• If it goes into the MDL, will it be filed directly there or transferred from another court?
• Which state’s deadlines apply to me?

About your role

• Will I need to fill out a plaintiff fact sheet, and will you help me?
• Could I be asked to give a deposition or go to trial?
• Do you need the removed implant, if I had a revision?

About fees and updates

• How are your fees and case costs handled, and can I see that in writing?
• In many MDLs, courts set aside a share of fees for lawyers who do shared work. How would that affect my case?
• How often will you update me, and who should I call with questions?

A steady approach

The Cartiva lawsuit will likely take time, and its outcome is not known. Asking clear questions, keeping good records and staying in touch with your doctor can help you make choices that fit your needs.

For many patients, the most useful step right now is simply understanding where things stand. A participating law firm may review your records and explain whether joining the Cartiva lawsuit makes sense for your situation.
