Hip knee implant failure lawsuit filings are growing rapidly across the United States. Patients who received defective hip or knee replacement devices face serious health risks. These include metallosis, bone loss, chronic pain, and the need for revision surgery. If your implant failed prematurely, you are not alone. Thousands of patients have filed claims against manufacturers like DePuy, Stryker, Zimmer Biomet, and Exactech. A licensed attorney can help you understand your legal options and potential compensation.
Understanding Hip Knee Implant Failure Lawsuit: Why Patients Are at Risk
Joint replacement patients trust that their devices will last 15 to 20 years. However, design defects and manufacturing failures have caused thousands of implants to fail much sooner. Metal-on-metal hip implants shed cobalt and chromium particles into surrounding tissue. Defective polyethylene liners crack and degrade inside the body. These failures often require painful revision surgery that costs $50,000 or more.
The FDA has issued multiple recalls affecting hundreds of thousands of patients. In 2022, Exactech recalled over 657,000 knee, hip, and ankle components. The packaging lacked a proper oxygen barrier. This caused the polyethylene to oxidize and degrade prematurely. Devices manufactured between 2004 and 2021 are affected. Many patients do not know their implant is part of this recall.
A hip knee implant failure lawsuit typically involves patients who experienced premature device failure. Symptoms include increasing pain, swelling, grinding sensations, and reduced mobility. Some patients develop metallosis, where metal debris accumulates in tissue. Others suffer cobalt poisoning that damages the heart, kidneys, and nervous system. These injuries often appear years after the original surgery.
Active Lawsuits Affecting This Group
Several multidistrict litigations are currently active in federal courts. The largest is MDL-3044 involving Exactech polyethylene devices. This case has 1,838 pending actions as of May 2026. Exactech filed for bankruptcy in October 2024, which temporarily paused litigation. A revised Chapter 11 plan was approved in September 2025. A litigation trust now pursues claims against TPG Capital, the private equity owner.
Patients considering a hip knee implant failure lawsuit should know which MDLs apply to their device. The following table shows active federal cases:
| MDL Number | Manufacturer | Device | Pending Cases | Injury Type |
|---|---|---|---|---|
| MDL-3044 | Exactech | Optetrak, Truliant, Connexion GXL | 1,838 | Polyethylene degradation, early failure |
| MDL-2197 | DePuy (J&J) | ASR XL Hip System | 119 | Metallosis, cobalt poisoning |
| MDL-2768 | Stryker | LFIT V40 Femoral Head | 55 | Taper lock failure, corrosion |
| MDL-2441 | Stryker | Rejuvenate / ABG II | 16 | Corrosion, metal release |
| MDL-2859 | Zimmer Biomet | M/L Taper, Versys | 2 | Fretting corrosion, loosening |
Previous hip knee implant failure lawsuit settlements have been substantial. DePuy paid $4 billion to resolve ASR claims. Stryker paid over $1 billion for Rejuvenate and ABG II cases. DePuy’s Pinnacle litigation resulted in a $1 billion global settlement. These figures demonstrate that manufacturers face significant liability for defective devices.
Eligibility and Evidence Requirements
You may qualify for a hip knee implant failure lawsuit if your device failed prematurely. Key eligibility factors include having a recalled or defective implant model. You must show that the device caused injury or required revision surgery. The implant must be from a manufacturer currently facing litigation. A diagnosis of metallosis, loosening, or component fracture strengthens your claim.
Medical records are the foundation of your case. Gather your original surgical records showing the device model and lot number. Obtain imaging studies such as X-rays, CT scans, or MRIs showing device failure. Blood tests revealing elevated cobalt or chromium levels are critical evidence. Pathology reports from revision surgery documenting tissue damage also help. Keep records of all related medical expenses and lost wages.
Special considerations apply to joint replacement patients. Many are older adults on fixed incomes who cannot easily afford revision surgery. Some patients received implants through the VA health system. Others have Medicare or Medicaid coverage that creates subrogation issues. Your attorney should understand how government benefits interact with a hip knee implant failure lawsuit recovery. Patients with multiple joint replacements may have claims for each affected device.
Step-by-Step: How to Check If You Qualify
Step 1: Identify your implant. Contact your orthopedic surgeon’s office and request your operative report. This document lists the exact manufacturer, model, and lot number. You can also request this information from the hospital where your surgery was performed. Check the FDA safety communications page for recall notices matching your device.
Step 2: Document your symptoms. Write down when pain, swelling, or mobility problems began. Note any clicking, grinding, or instability in the joint. Request blood work to check cobalt and chromium levels. Levels above 7 micrograms per liter indicate potential metal toxicity. Ask your doctor if imaging shows loosening, bone loss, or tissue damage around the implant.
Step 3: Consult a qualified attorney experienced in hip knee implant failure lawsuit cases. Most offer free case evaluations with no upfront costs. Bring your operative report, medical records, and symptom timeline. The attorney will determine which MDL or state court action applies to your situation. Do not delay. Statutes of limitations range from one to six years depending on your state. The clock typically starts when you discover the injury is linked to the device.
Financial Considerations and Timeline
Most attorneys handling a hip knee implant failure lawsuit work on contingency. You pay nothing upfront. The attorney receives a percentage of your recovery, typically 33% to 40%. If you receive no compensation, you owe nothing. This arrangement makes legal action accessible regardless of your financial situation. Ask about case expenses and whether you must repay costs if the case is unsuccessful.

Settlement timelines vary significantly by case. Individual cases resolved through MDL settlements have historically paid within 12 to 24 months of agreement. However, the Exactech bankruptcy has complicated the timeline for those claims. Prior hip implant settlements have ranged from $50,000 to over $500,000 per plaintiff. Cases involving revision surgery, cobalt poisoning, or permanent disability typically recover more. A bellwether trial verdict can accelerate settlement negotiations for all pending cases.
Your potential compensation in a hip knee implant failure lawsuit may cover medical expenses including revision surgery costs. It may also include future medical care, lost income, pain and suffering, and reduced quality of life. Patients who suffered systemic injuries like heart damage or kidney failure may qualify for higher amounts. Every case is different. Consult a licensed attorney to evaluate your specific circumstances and potential recovery.
Finding the Right Attorney
Look for an attorney with specific experience in medical device litigation. Ask how many hip knee implant failure lawsuit cases they have handled. Inquire about their track record with the manufacturer involved in your case. Experienced firms often have relationships with medical experts who can evaluate your implant failure. They understand the technical evidence needed to prove defective design or manufacturing.
Verify the attorney’s credentials through your state bar association. Check whether they are admitted to practice in the court handling your MDL. Ask about their communication practices. You deserve regular updates on your case status. A good attorney will explain the process clearly and set realistic expectations about timeline and potential outcomes.
Consider attorneys who handle cases nationwide for hip knee implant failure lawsuit claims. MDL cases are consolidated in specific federal courts regardless of where you live. Your attorney does not need to be in the same state as the court. However, they should be familiar with local filing requirements in your state for statute of limitations purposes. The Judicial Panel on Multidistrict Litigation website lists all active MDLs and their assigned courts.
Frequently Asked Questions
How do I know if my implant is part of a recall or active hip knee implant failure lawsuit?
Contact your surgeon’s office for your operative report listing the device model and lot number. Then check the FDA medical device recall database for matching recalls. An experienced attorney can also identify whether your device is part of active litigation. Many law firms offer free device identification services as part of their initial case review.
What if my surgery was many years ago — can I still file a hip knee implant failure lawsuit?
Possibly yes. Most states apply a “discovery rule” for medical device cases. The statute of limitations begins when you discover, or reasonably should have discovered, that your injury is linked to the device. This is often the date you received a recall notice, were diagnosed with metallosis, or were told you need revision surgery. However, some states impose an absolute deadline called a statute of repose. Consult an attorney immediately to protect your rights.
Does filing a hip knee implant failure lawsuit affect my current medical care or insurance?
No. Filing a lawsuit does not interfere with your ongoing medical treatment. Your doctors will continue providing care as needed. Your health insurance remains unaffected. However, your insurer may have a subrogation interest in any recovery you receive. This means they could seek reimbursement for medical costs they paid. Your attorney will address this as part of your settlement negotiations to maximize your net recovery.
