Knee replacements are artificial implants used to replace part or all of a damaged knee joint. Made by various manufacturers, knee replacements can restore mobility and relieve pain. Despite their efficacy for some patients, however, knee replacements have been associated with some serious, possibly deadly complications.
The dangerous medical device lawyers at the Amaro Law Firm are ready to explain your legal options and help you get on the path to recovery and justice if you or someone you love has suffered a serious complication related to a knee replacement. Dedicated to providing unparalleled representation, we can effectively advocate your rights while positioning your case for the best possible outcome.
Defective knee implants have been associated with serious complications and painful revision surgery. Injured patients can recover and hold negligent manufacturers accountable by filing a defective knee implant claim.
Also referred to as knee implants, knee replacements are most commonly used in patients between 50 and 80 years old who have suffered serious knee damage due to trauma or conditions like (but not limited to):
Osteoarthritis or rheumatoid arthritis
Osteonecrosis (bone death).
While knee implant components can be made of metal, ceramic and/or plastics, generally, these devices are comprised of a:
Femoral component, which attaches to the thighbone and connects with the patellar component
Patellar component, which mimics the kneecap and lies between the other two components
Tibial component, which attaches to the shinbone and connects with the patellar component.
Knee implants can be secured via bone cement, which is generally used for less active or older patients, or cementless techniques, which is usually reserved for younger patients with strong bone structure surrounding the knee joint. When properly implanted, knee replacements typically last for about 15 years.
Companies that make knee replacements include (but may not be limited to):
DePuy Synthes, with model lines including the Attune, the LCS Complete, the Sigma and the S-ROM Noiles
Smith & Nephew, with model lines including the Genesis II, the Journey II and the Legion
Stryker, with model lines including the Avon Patello-Femoral, the Duracon TS, the Scorpio, the Triathalon and the Triathlon Tritanium
Zimmer-Biomet, with model lines including Gender Solutions, the Zimmer NexGen, the Zimmer Persona, the Oxford and the Vanguard Individualized Design.
Serious Knee Replacement Problems & Complications
Knee implants have been linked to a number of serious complications, including (but not necessarily limited to):
Implant loosening & dislocation – Improper implantation, as well as fretting of the device components, can cause knee implants to loosen, increasing the risk of device dislocation and failure.
Metallosis – This occurs when metal-on-metal (MoM) components of knee implants rub against each other and release metal particles into the body. The accumulation of these particles causes this form of metal poisoning, which can be fatal without treatment.
Serious infection – This condition, which can contribute to implant loosening, can also be deadly without treatment. Patients with rheumatoid arthritis or diabetes tend to have the highest risk of infection.
Risky, painful revision surgery is usually required to treat serious knee replacement complications. According to a March 2011 study,1 rates of revision surgery for knee replacements are about:
6 percent after 5 years
12 percent after 10 years.
Knee Replacement Recalls
Device-related flaws have led to the recall of more than 700 different knee implant components and devices over the past decade. According to the latest data,2 these knee implant recalls have included (and may not be limited to):
299 recalls from Zimmer-Biomet
277 recalls from DePuy
118 recalls from Stryker
11 recalls from Smith & Nephew.
While most of these were Class II recalls (meaning that the component or device was associated with serious risks), DePuy was associated with four Class I recalls, indicating a component or device is linked to fatal risks and complications.
Thousands who have suffered knee replacement complications have already taken action to hold the manufacturers liable. Their claims generally allege that:
Knee replacements caused serious injuries.
The makers of knee implants were negligent in testing the safety of their devices, as well as in warning the public about the serious device-related risks and dangers.
While multidistrict litigation has been set up for some claims – like those associated with Zimmer NexGen Implants (MDL No. 2272),3 others are pending independently in state courts.
Whether it is best for newly filed claims to join the ongoing MDL or proceed independently will depend on the details of the claim, as well as a plaintiff’s needs and objectives.
