Joint replacement surgery is one of the most common and successful orthopedic procedures performed in the United States, with over 1 million hip and knee replacements conducted annually. For most patients, artificial joints restore mobility and dramatically improve quality of life. But when an artificial joint is defective — due to flawed design, manufacturing errors, or inadequate testing — the results can be painful, debilitating, and require additional surgery to correct.
Defective artificial joints have been the subject of some of the largest product liability lawsuits and recalls in medical device history. Major manufacturers including DePuy (a Johnson & Johnson subsidiary), Stryker, Zimmer Biomet, Smith & Nephew, and Wright Medical have all faced significant litigation over defective joint implants. For New Mexico patients who have experienced problems with an artificial joint, understanding your legal rights is essential.
Common Defects in Artificial Joints
Metal-on-Metal (MoM) Hip Implants
Metal-on-metal hip implants were marketed as more durable alternatives to traditional metal-on-polyethylene designs. However, many MoM implants have been found to release microscopic metal particles (cobalt and chromium) into surrounding tissue, causing a condition known as metallosis. Symptoms include:
- Chronic pain and swelling
- Tissue death (necrosis) around the implant
- Bone loss (osteolysis)
- Pseudotumors — masses of inflamed tissue
- Elevated blood metal levels causing systemic toxicity
- Premature implant failure requiring revision surgery
Premature Loosening and Failure
Some artificial joints fail prematurely — well before their expected lifespan — due to design flaws, inadequate fixation mechanisms, or materials that wear faster than anticipated. When an implant loosens, it causes pain, instability, and bone damage, typically requiring revision surgery.
Component Fracture
Defective materials or manufacturing processes can cause implant components to fracture under normal use. A fractured implant component can cause sudden pain, loss of mobility, and internal tissue damage.
Corrosion at the Taper Junction
Modular hip implants — which consist of separate components joined at a taper junction — can experience corrosion and fretting at the junction point. This releases metal debris and can cause the components to loosen or dissociate.
Major Artificial Joint Recalls
- DePuy ASR Hip System (2010) — Recalled after data showed failure rates of approximately 12-13% within five years, far exceeding acceptable rates. Over 93,000 devices were recalled worldwide.
- Stryker Rejuvenate and ABG II (2012) — Recalled due to corrosion and fretting at the modular neck-stem junction, causing metallosis and tissue damage.
- Zimmer NexGen Knee (ongoing litigation) — Lawsuits alleging premature loosening and failure of the tibial component.
- Wright Medical Conserve Hip (litigation) — Metal-on-metal design linked to high failure rates and metallosis.
Legal Theories in Defective Joint Cases
New Mexico product liability law allows patients to pursue claims under multiple theories:
Strict Liability
Manufacturers are strictly liable for injuries caused by defective products under New Mexico’s adoption of the Restatement (Second) of Torts § 402A. This applies to design defects, manufacturing defects, and failure to warn.
Negligence
Manufacturers who failed to exercise reasonable care in designing, testing, or monitoring their implants can be held liable for negligence.
Failure to Warn
If the manufacturer knew or should have known about defect risks and failed to warn surgeons and patients, they may be liable for failure to warn.
Who Can Be Held Liable?
- The implant manufacturer
- Component suppliers
- The surgeon — if they were negligent in selecting or implanting the device (a medical malpractice claim)
- The hospital — if institutional negligence contributed to the harm
Statute of Limitations
New Mexico’s statute of limitations for personal injury claims is three years from the date the injury was discovered or should have been discovered (N.M. Stat. § 37-1-8). The discovery rule is critical in defective joint cases, as problems may not manifest until years after implantation.
Compensation Available
Patients harmed by defective artificial joints may recover:
- Medical expenses for revision surgery, rehabilitation, and ongoing care
- Lost wages and diminished earning capacity
- Pain and suffering
- Emotional distress
- Loss of enjoyment of life
- Punitive damages for egregious manufacturer conduct
Frequently Asked Questions
How do I know if my artificial joint is defective?
Warning signs include persistent or worsening pain, swelling, clicking or grinding sounds, reduced mobility, and instability. If you experience these symptoms, consult your orthopedic surgeon. You can also check the FDA’s medical device recall database and consult a product liability attorney.
What if my implant was recalled?
A recall strengthens your product liability claim. Follow your doctor’s recommendations regarding monitoring or revision surgery, and contact an attorney to discuss your legal options.
Can I sue even if my implant hasn’t failed yet?
Generally, product liability claims require proof of actual injury. However, if you have elevated blood metal levels or other documented health effects from a defective implant, you may have a claim even before the implant mechanically fails.
How long do defective joint cases take?
Individual cases typically take one to three years. Cases consolidated in multidistrict litigation may follow a different timeline based on bellwether trials and settlement negotiations.
